Inspection Procedure

1. PREPARATION
Refer to the DESCRIPTION in this TROUBLESHOOTING section.
2. CHECK SIS CIRCUIT
(1) Measure resistance between the terminal 1 of SIS harness connector and the terminal 14(16) of SRSCM harness connector(B).
(2) Measure resistance between the terminal 2 of SIS harness connector and the terminal 13(15) of SRSCM harness connector(B).

Specification (resistance) : below 1 Ohms





(3) Is the measured resistance within specification?
YES
>Check Side Impact Sensor.
NO
> Repair or replace the wiring harness between the SIS and the SRSCM.
3. CHECK THE SIDE IMPACT SENSOR
(1) Replace the Side Impact Sensor(SIS) with a new one.
Refer to "Side Impact Sensor(SIS)" section in this SERVICE MANUAL.
(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 a 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 Side Impact Sensor(SIS)?
YES
> Go to next step.
NO
> Replace SIS.
4. CLEAR THE DTC AND CHECK THE VEHICLE AGAIN
Refer to the DESCRIPTION in this TROUBLESHOOTING section.
