Pinpoint Test - Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS)

Pinpoint Test A: The Air Bag Warning Indicator is Illuminated Continuously 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

During normal operation, the instrument cluster (IC) module will illuminate the air bag indicator continuously for 6 seconds after the ignition switch is placed to the RUN or ON position. If the supplemental restraint system (SRS) is fault free, the air bag warning indicator will turn off and remain off. If a fault is detected in the SRS, the air bag warning indicator will illuminate and remain illuminated for the rest of the key cycle. The restraints control module (RCM) will communicate to the IC module via the high-speed controller area network (HS-CAN). The IC module will illuminate the air bag indicator based on messaging from the RCM or if there is no communication between the RCM and IC module.

This pinpoint test is intended to diagnose the following:

PINPOINT TEST A: THE AIR BAG WARNING INDICATOR IS ILLUMINATED CONTINUOUSLY 

WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the safety canopy and cause serious personal injury or death.
WARNING: Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: SRS components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS. 
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. A1 CHECK FOR CONTINUOUS AND ON-DEMAND DTCs 
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Self Test - RCM - Retrieve and Record On-Demand and Continuous Memory DTCs
    • Were any continuous memory or on-demand DTCs retrieved? 
    1. YES  : If on-demand or continuous memory DTCs were retrieved, go to the DTC Charts  for diagnostic direction.

      Do not clear any DTCs until all DTCs have been resolved.

    2. NO  : If the RCM does  communicate with the scan tool, REFER to INSTRUMENT CLUSTER (IC), MESSAGE CENTER & WARNING CHIMES article to diagnose the IC module concern.

      If the RCM does not  communicate with the scan tool, REFER to MODULE COMMUNICATIONS NETWORK article to diagnose the no communication concern.

      Do not clear any DTCs until all DTCs have been resolved.

Pinpoint Test B: DTC B1342 - ECU (OCSM) is Faulted 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

The occupant classification sensor (OCS) system is used to classify the front passenger seat occupant in the event of a deployable impact. Refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) .

The occupant classification system module (OCSM) monitors internal circuity, hardware and the 4 OCS weight sensor bolts and external circuitry for faults. If the OCSM detects a fault with the internal circuitry, internal hardware, sensor(s) or external circuitry, it will store DTC B1342 in memory and send a message to the restraints control module (RCM). A short to ground on any one of the sensor reference voltage circuits or an open on 3 or more of the sensor reference voltage circuits may set this DTC. The RCM will store DTC B2290 in memory and send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

Fault PIDsa Description Fault Trigger Condition
1342_27_OD and 1342_27_CM Memory Fault When the OCSM senses a internal hardware failure, a fault will be indicated.
1342_28_OD and 1342_28_CM Microcontroller Internal Fault When the OCSM senses a internal failure, a fault will be indicated.
1342_29_OD and 1342_29_CM Satellite ASIC Fault When the OCSM senses a internal hardware failure, a fault will be indicated.
1342_30_OD and 1342_30_CM Power Supply Internal Fault When the OCSM senses a failure with the internal power supply, a fault will be indicated.

a Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B1342. Fault PIDs that end in CM indicate continuous memory status and are associated with continuous DTC B1342.

This pinpoint test is intended to diagnose the following:

Pinpoint Test C: DTC B1868 - Lamp Air Bag Warning Indicator Circuit Failure 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

During normal operation, the air bag warning indicator will illuminate continuously for approximately 6 seconds and then go out after the ignition switch is placed in the ON position and no air bag fault exists. Control of the air bag warning indicator is a function of the instrument cluster (IC) module based on information it receives from the restraints control module (RCM) over the high-speed controller area network (HS-CAN). The default mode for the air bag warning indicator is on. The RCM sends a message to the IC module to turn the indicator off if no air bag fault exists. If the RCM detects a problem with the supplemental restraints system (SRS) it will send a message to the IC module to turn the air bag warning indicator on.

If the IC module detects a problem with the air bag warning indicator, it will send a fault message to the RCM and the RCM will store DTC B1868 in memory.

This pinpoint test is intended to diagnose the following:

Pinpoint Test G: DTC B2292 - Restraint System - Seatbelt Pretensioner Fault 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

The restraints control module (RCM) continuously monitors the safety belt retractor pretensioner circuits for an acceptable resistance range, unacceptable voltage and shorts to ground. The RCM will set on-demand and store DTC B2292 in memory if any of these conditions are detected to be outside of their respectful range. If the RCM detects a fault, it will send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.

As the RCM continuously monitors safety belt retractor pretensioner circuits for resistance, it expects a normal resistance between 1.4 and 3.5 ohms.

If a loop resistance is between 0.9 and 1.4 or between 3.5 and 5 ohms, there exists a strong potential for an intermittent fault, a DTC may or may not set. The RCM will also set an on-demand DTC if the loop resistance is less than 0.9 ohm or greater than 5 ohms.

Fault PIDsa Description Fault Trigger Condition
2292_24_OD and 2292_24_CM Pretensioner Circuit Short to Ground, Front Passenger Side When the RCM senses a short to ground on either of the passenger pretensioner circuits, a fault will be indicated.
2292_25_OD and 2292_25_CM Pretensioner Circuit Short to Battery, Front Passenger Side When the RCM senses a short to voltage on either of the passenger pretensioner circuits, a fault will be indicated.
2292_26_OD and 2292_26_CM Pretensioner Circuit Open, Front Passenger Side When the RCM measures resistance greater than 5 ohms between the passenger pretensioner circuits, a fault will be indicated.
2292_27_OD and 2292_27_CM Pretensioner Circuit Resistance Low, Front Passenger Side When the RCM measures resistance less than 0.9 ohm between the passenger pretensioner circuits, a fault will be indicated.
2292_28_OD and 2292_28_CM Pretensioner Circuit Short to Ground, Front Driver Side When the RCM senses a short to ground on either of the driver pretensioner circuits, a fault will be indicated.
2292_29_OD and 2292_29_CM Pretensioner Circuit Short to Battery, Front Driver Side When the RCM senses a short to voltage on either of the driver pretensioner circuits, a fault will be indicated.
2292_30_OD and 2292_30_CM Pretensioner Circuit Open, Front Driver Side When the RCM measures resistance greater than 5 ohms between the driver pretensioner circuits, a fault will be indicated.
2292_31_OD and 2292_31_CM Pretensioner Circuit Resistance Low, Front Driver Side When the RCM measures resistance less than 0.9 ohm between the driver pretensioner circuits, a fault will be indicated.

a Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B2292. Fault PIDs that end in CM indicate continuous memory status and are associated with continuous DTC B2292.

NOTE: When monitoring fault and/or resistance PIDs with the scan tool, it may take up to 2 seconds for the scan tool display to update.

Pinpoint Test H: DTC B2293 - Restraint System - Air Bag Fault 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

The restraints control module (RCM) continuously monitors all front air bag module circuits (loop) for an acceptable resistance range, unacceptable voltage and shorts to ground. The RCM will set on-demand and store DTC B2293 in memory if any of these conditions are detected to be outside of their respectful range. If the RCM detects a fault, it will send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

As the RCM continuously monitors all front air bag module circuits for resistance, it expects a normal resistance for the driver air bag module loop 1 and 2, between 1.7 and 4.4 ohms.

The normal expected resistance for the passenger air bag module loop 1 and 2 is between 1.4 and 3.5 ohms.

If a loop resistance for the driver air bag loop 1 or 2 is between 0.9 and 1.7 or between 4.4 and 5 ohms, there exists a strong potential for an intermittent fault, a DTC may or may not set. The RCM will also set an on-demand DTC if the loop resistance is less than 0.9 ohm or greater than 5 ohms.

If a loop resistance for the passenger air bag loop 1 & 2 is between 0.9 and 1.4 or between 3.5 and 5 ohms, there exists a strong potential for an intermittent fault, a DTC may or may not set. The RCM will also set an on-demand DTC if the loop resistance is less than 0.9 ohm or greater than 5 ohms.

Pinpoint Test I: DTC B2294 - Restraint System - Curtain Fault 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

The restraints control module (RCM) continuously monitors the driver and passenger safety canopy module circuits (loop) for an acceptable resistance range, unacceptable voltage and shorts to ground. The RCM will set on-demand and store DTC B2294 in memory if any of these conditions are detected to be outside of their respectful range. If the RCM detects a fault, it will send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

As the RCM continuously monitors safety canopy module circuits for resistance, it expects a normal resistance between 1.4 and 3.5 ohms.

If a loop resistance is between 0.9 and 1.4 or between 3.5 and 5 ohms, there exists a strong potential for an intermittent fault, a DTC may or may not set. The RCM will also set an on-demand DTC if the loop resistance is less than 0.9 ohm or greater than 5 ohms.

Pinpoint Test J: DTC B2295 - Restraint System - Side Air Bag Fault 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

A seat side air bag module provides protection of the thorax area (between the neck and abdomen) of the body, working in conjunction with the head protection provided by a safety canopy module. Refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) .

The restraints control module (RCM) continuously monitors the driver and passenger side air bag module circuits (loop) for an acceptable resistance range, unacceptable voltage and shorts to ground. The RCM will set on-demand and store DTC B2295 in memory if any of these conditions are detected to be outside of their respectful range. If the RCM detects a fault, it will send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

As the RCM continuously monitors side air bag module circuits for resistance, it expects a normal resistance between 1.4 and 3.5 ohms.

If a loop resistance is between 0.9 and 1.4 or between 3.5 and 5 ohms, there exists a strong potential for an intermittent fault, a DTC may or may not set. The RCM will also set an on-demand DTC if the loop resistance is less than 0.9 ohm or greater than 5 ohms.

Fault PIDsa Description Fault Trigger Condition

2295_27_OD and 2295_27_CM Side Air Bag Circuit Short to Battery, Front Passenger Side When the RCM senses a short to voltage on either of the passenger side air bag module circuits, a fault will be indicated.
2295_28_OD and 2295_28_CM Side Air Bag Circuit Resistance Low, Front Driver Side When the RCM measures less than 0.9 ohm between the driver side air bag module circuits, a fault will be indicated.
2295_29_OD and 2295_29_CM Side Air Bag Circuit Open, Front Driver Side When the RCM measures greater than 5 ohms between the driver side air bag module circuits, a fault will be indicated.
2295_30_OD and 2295_30_CM Side Air Bag Circuit Short to Ground, Front Driver Side When the RCM senses a short to ground on either on the driver side air bag module circuits, a fault will be indicated.
2295_31_OD and 2295_31_CM Side Air Bag Circuit Short to Battery, Front Driver Side When the RCM senses a short to voltage on either on the driver side air bag module circuits, a fault will be indicated.

a Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B2295. Fault PIDs that end in CM indicate continuous memory status and are associated with continuous DTC B2295.

Pinpoint Test L: DTC B2432 - Drivers Seat Belt Buckle Switch Circuit Open 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

The restraints control module (RCM) checks the safety belt buckle switch circuits for faults. If the RCM detects an open circuit fault, it will store DTC B2432 in memory and send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

This pinpoint test is intended to diagnose the following:

PINPOINT TEST L: DTC B2432 - DRIVERS SEAT BELT BUCKLE SWITCH CIRCUIT OPEN 

WARNING: Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the safety canopy and cause serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
WARNING: Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which increases the risk of serious personal injury or death.
NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Supplemental restraint system (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS. 
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test Z: DTC B1013 - Occupant Classification Calibration Fault 

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information.

Normal Operation 

The occupant classification sensor (OCS) system is used to classify the front passenger seat occupant in the event of a deployable impact. Refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) .

The occupant classification system module (OCSM) monitors the OCS weight sensor bolts for a correct calibration/weight and ID from each sensor. If the OCSM detects an incorrect weight or ID from any of the 4 seat weight sensors, a seat track that is mis-aligned/bent, wire harness connected to the incorrect OCS weight sensor bolt, an unsuccessful system reset or if an OCS system component has been installed new, it will store DTC B1013 in memory and send a message to the restraints control module (RCM) which stores DTC B2290 in memory. The RCM will then send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

This pinpoint test is intended to diagnose the following:

PINPOINT TEST Z: DTC B1013 - OCCUPANT CLASSIFICATION CALIBRATION FAULT 

NOTE: Do not install any new OCS system components until directed to do so during the pinpoint test. 
NOTE: The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: If a new OCS system component has been installed, the OCSM will store DTC B1013, causing the air bag warning indicator to illuminate during the prove out. This DTC will clear after a successful system reset.
