2. Is the measured resistance within specification?

   YES 

   • Check OC Module.

   NO 

   • Repair or replace 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) .
2. Install the DAB module and connect the DAB connector.
3. Connect the connectors of the PAB, SAB, CAB, BPT, FIS and SIS.
4. Connect the SRSCM connector.
5. Connect the battery negative cable to the battery.
6. Connect the a Hi-Scan (Pro) to the data link connector.
7. Turn the ignition switch to ON and check the vehicle again.
8. Does Hi-Scan (Pro) indicate any DTC related to OC Module?

   YES 

   • Go to next step.

   NO 

   • Replace the OC Module.

Refer to CLEAR THE DTC AND CHECK THE VEHICLE AGAIN .
