INSPECTION PROCEDURE

1. CHECK CIRCUIT
1. Turn the ignition switch to LOCK.
2. Disconnect the negative (-) terminal from the battery and wait for at least 3 minutes.
3. Remove the DAB module and disconnect the DAB connector.
4. Disconnect the connectors of the PAB, SAB, CAB, BPT, BUPT, FIS and SIS.
5. Disconnect the SRSCM connector.
6. Measure resistance between airbag module wiring harness and the other wiring harness (ex. DAB vs PAB, DAB vs SAB, DAB vs CAB, DAB vs BPT, DAB vs BUPT etc.)

specification(resistance) : infinite

Is the measured resistance within specification?

YES - Replace SRSCM, then go to "CLEAR THE DTC AND CHECK THE VEHICLE AGAIN".

NO - Repair or replace the wiring harness, then go to "CLEAR THE DTC AND CHECK THE VEHICLE AGAIN".

2. 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 Hi-Scan (Pro) to the data link connector.
6. Turn the ignition switch to ON.
7. Clear the DTC stored in the SRSCM memory with the Hi-Scan (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 Hi-Scan (Pro).

Does the above DTC(s) go off?

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

NO - 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).
