Diagnostic Test
WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
- DETERMINE ACTIVE OR STORED DTC NOTE: Ensure the battery is fully charged.NOTE: The scan tool, SRS Airbag Load Tool MRL 8443A, and DVOM are required to perform the following test.
- CHECK FOR SHORTED SQUIB CIRCUITS IN PASSENGER AIRBAG
WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- Disconnect the Passenger Airbag Squib connector.WARNING: Do not place an intact undeployed airbag face down on a hard surface, the airbag will propel into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury.NOTE: Check the connectors - Clean and repair as necessary.
- Connect the SRS Load Tool kit 8443A to the Passenger Airbag Squib connector.WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- With the scan tool, read the active ORC DTC's.
Does the scan tool display: B1B0F-PASSENGER AIRBAG SQUIB 2 CIRCUIT SHORTED TOGETHER?
Yes
- Go to step 3
No
- Replace the Passenger Airbag in accordance with the Service Information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Disconnect the Passenger Airbag Squib connector.
- CHECK (R64) PASSENGER SQUIB 2 LINE 1 CIRCUIT FOR A SHORT TO (R62) PASSENGER SQUIB 2 LINE 2 CIRCUIT
WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- Disconnect the 8443A Load Tool from the Passenger Airbag Squib connector.
- Disconnect the ORC connectors.NOTE: Check connectors - Clean and repair as necessary.
- Connect the 8443-24 Load Tool ORC Adaptor to the ORC C2 connector.
- Measure the resistance between the (R64) Passenger Squib 2 Line 1 circuit and the (R62) Passenger Squib 2 Line 2 circuit at the Passenger Airbag Squib connector.
Is the resistance less than or equal to the range of 1.24 - 1.71 Ohms?
Yes
- Repair the (R64) Passenger Squib 2 Line 1 circuit for a short to the (R62) Passenger Squib 2 Line 2 circuit.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
No
- Go to step 4
- REPLACE THE ORC WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
Repair
- Replace the ORC in accordance with the Service Information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- STORED ORC DTC
- With the scan tool, record and erase all DTCs from all Airbag System Modules.
- If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
- The following additional checks may assist you in identifying a possible intermittent problem.
- Reconnect any disconnected components and harness connector.WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- With the scan tool monitor active codes as you work through the following steps.
- Wiggle the wiring harness and connectors of the related airbag circuit or component.
- If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
- If only stored codes return continue the test until the problem area has been isolated.
- In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.
Are any ACTIVE DTCs present?
Yes
- Select the appropriate diagnostic procedure. Refer to DIAGNOSTIC CODE INDEX .
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
