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 OCCUPANT CLASSIFICATION SENSOR (OCS)  in this SERVICE INFORMATION.

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 " 7 OC (PODS) Reset" procedure.

   NO 

   • Replace OC module.

The following procedures are to be followed to erase the PODS ECU diagnostic codes and for PODS ECU initialization.

1. Turn on Hi-Scan Pro and select the Azera model.
2. Select SRS-AIRBAG.
