Inspection Procedure

Refer to the DESCRIPTION in this TROUBLESHOOTING part. (PREPARATION OF INSPECTION  )

1. Measure resistance between the terminal 4 of OC module harness connector and the terminal 36 of SRSCM harness connector (B).
2. Measure resistance between the terminal 5 of OC module harness connector and the terminal 37 of SRSCM harness connector (B).

   specification (resistance): below 1 Ω

3. Is the measured resistance within specification?

   YES 

   • Check short to ground.

   NO 

   • Repair the open circuit on wiring harness between the OC module and the SRSCM.

1. Measure resistance between the terminal 4 of OC module harness connector and chassis ground.

   Specification (resistance): infinite

2. Is the measured resistance within specification?

   YES 

   • Go to next stop.

   NO 

   • Repair or replace the wiring harness between the OC module and the SRSCM.

1. Connect the battery negative cable to the battery.
2. Turn the ignition switch to ON.
3. Measure voltage between the terminal 4 of OC module harness connector and chassis ground.

   specification (voltage): Approximately 0 V

4. Is the measured voltage within specification?

   YES 

   • Check the OC module.

   NO 

   • Repair the short to battery line on the wiring harness between the OC module and the SRSCM.

1. Replace the OC module with a new one.
   • Refer to OCS.
2. Turn the ignition switch to LOCK.
3. Connect the OC module connector.
4. Connect the SRSCM connector.
5. Connect the battery negative cable to the battery.
6. Connect Hi-Scan (Pro) to the data link connector.
7. Turn the ignition switch to ON and check the vehicle again.

   Does Hi-Scan (Pro) indicate any DTC related to OC module?

   YES 

   • Go to next step.

   NO 

   • Replace OC module.
