4. Disconnect the connectors of the PAB, SAB, CAB, BPT, BUPT, FIS and SIS.
5. Disconnect the SRSCM connector.

2. CHECK SHORT TO GROUND
1. Measure resistance between the terminal 4 of PAB harness connector and chassis ground.(PAB stage #1)




2. Measure resistance between the terminal 1 of PAB harness connector and chassis ground.(PAB stage #2)

specification(resistance) : infinite

Is the measured resistance within specification?

YES: Check the PAB Module.

NO: Repair or replace the wiring harness between the PAB and the SRSCM.
