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

6. CHECK THE OC MODULE

(1) Replace the OC module with a new one.

● Refer to OCS section in this SERVICE MANUAL.

(2) Turn the ignition switch to LOCK.

(3) Connect the OC module connector.

(4) Connect the SRSCM connector.

(5) Connect the negative(­) terminal to the battery.

(6) Connect Hi­Scan(Pro) to the data link connector.

(7) Turn the ignition switch to ON and check the vehicle again.

Does Hi­Scan(Pro) indicate any DTC related to OC module?

►

 Go to next step.

►

 Replace OC module.

7. CLEAR THE DTC AND CHECK THE VEHICLE AGAIN

(1) Install the DAB module and connect the DAB connector.

(2) Connect the connectors of the PAB, SAB, CAB, BPT, BUPT, FIS and SIS.

(3) Connect the SRSCM connector.

(4) Connect the negative (­) terminal to the battery.

(5) Connect a Hi­Scan(Pro) to the data link connector.

(6) Turn the ignition switch to ON .

(7) Clear the DTC stored in the SRSCM memory with the Hi­Scan(Pro).

(8) Turn the ignition switch to LOCK and wait for at least 30 seconds.

(9) Turn the ignition switch to ON and wait for at least 30 seconds.

(10) Check the vehicle again with the Hi­Scan(Pro).

Does the above DTC(s) go off?

►

 Problem is intermittent or was repaired and SRSCM memory was not cleared.

►

Replace the SRSCM with a new one, and then check the vehicle again. At this time, if the vehicle normally

operates with a new SRSCM, the fault may be the SRSCM(Replace SRSCM).
