Pinpoint Test A : B00C2:11 And B00C2:12
- A1 RETRIEVE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- REFER to: SAFETY BELT AND SUPPLEMENTAL RESTRAINT SYSTEM (SRS) HEALTH AND SAFETY PRECAUTIONS .
- Ignition ON.
- Using a diagnostic scan tool, perform OCSM self-test.
WARNING: Before beginning any service procedure in this service information, refer to Safety Warnings in SERVICE INFORMATION General Information. Failure to follow this instruction may result in serious personal injury.Was DTC B00C2:11 or B00C2:12 retrieved on-dem and during self-test?
- A2 CHECK THE BELT TENSION SENSOR (BTS) WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.NOTE: This pinpoint test step attempts to change the fault reported by the OCSM by inducing a different fault condition. If the fault reported changes, this indicates the OCSM is functioning correctly and is not the source of the fault.
- Ignition OFF.
- Disconnect Passenger Safety Belt Buckle C3238.
- Using a diagnostic scan tool, perform OCSM self-test.
- DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the Belt Tension Sensor (BTS) disconnected, an open circuit fault is normally retrieved. Because the Belt Tension Sensor (BTS) shares a connector with the passenger safety belt buckle switch, a passenger safety belt buckle switch circuit fault will also be present in the RCM.

- A5 CONFIRM THE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) FAULT WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.NOTE: Make sure all OCS system components, restraint system sensor electrical connectors and the RCM electrical connectors are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.
- Ignition OFF.
- Prior to reconnecting any previously disconnected SRS component:
- inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
- inspect wire harness for any damage, pinched, cut or pierced wires.
- repair any concerns found.
Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.
- Connect OCSM C3159 (if previously disconnected).
- Connect Passenger Safety Belt Buckle C3238.
- If previously directed to disconnect Passenger Seat Side Airbag (Inline) C3007B, depower the SRS.
REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .
- Connect Passenger Seat Side Airbag (Inline) C3007B(if previously disconnected).
- Tighten to 1 Nm (9 lb-in).
- If previously directed to depower the SRS, repower the SRS. Do not prove out the SRS at this time.
REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .
- Ignition ON.
- Using a diagnostic scan tool, perform OCSM self-test.
Was the original DTC retrieved on-dem and during self-test?
- Yes:
CHECK OASIS
for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new OCS sensor.

REFER to: Occupant Classification System (OCS) Sensor - Vehicles Built From: 11-June-2012 .
GO to A7
- No: In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test. GO to A6
- A6 CHECK FOR AN INTERMITTENT FAULT WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
- Ignition OFF.
- Disconnect Passenger Safety Belt Buckle C3238.
- inspect connector(s) (including any inline connectors) for loose or spread terminals and loose or frayed wire connections at terminals.
- inspect wire harness for any damage, pinched, cut or pierced wires.
- repair any concerns found.
Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.
- Connect Passenger Safety Belt Buckle C3238.
- Ignition ON.
- Using a diagnostic scan tool, perform OCSM self-test to retrieve Diagnostic Trouble Codes (DTCs).
Was DTC B00C2:11 or B00C2:12 retrieved on-dem and during self-test?
- Yes: The fault condition is now present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-dem and during the self-test. For DTC B00C2:11, GO to A2 For DTC B00C2:12, GO to A4
- No: CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. ACTIVATE other system in the same wire harness. Do not install any new SRS components at this time. Only install SRS components when directed to do so in the pinpoint test. REPAIR any intermittent concerns found. GO to A7
- A7 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS) WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
- Ignition OFF.
- If previously directed to disconnect Passenger Seat Side Airbag (Inline) C3007B, depower the SRS.
