CIRCUIT DESCRIPTION

DTC Detection Condition:

The squib circuit consists of the SRSCM, clock spring, DAB, PAB, FSAB, RSAB, CAB, BPT, FIS and SIS. It causes the SRS to deploy when the SRS deployment conditions are satisfied. The above DTCs are recorded when a short to ground is detected in the SAB squib circuit.

NOTE:
- DAB: Driver Airbag
- PAB: Passenger Airbag
- FSAB: Front Side Airbag, Side Airbags Located in Driver and Passenger Seat
- RSAB: Rear Side Airbag, Side Airbags Located in rear seats
- CAB: Curtain Airbag
- BPT: Belt Pretensioner
- SIS: Side Impact Sensor
- FIS: Front Impact Sensor
- BS: Belt Buckle Switch
- SRSCM: Supplemental Restraints System Control Module

INSPECTION PROCEDURE

1. Preparation
1. Disconnect negative (-) terminal cable from the battery, and wait at least 30 seconds.
2. Disconnect the connector of the FSAB and RSAB module.
3. Disconnect the connector of the SRSCM.




2. Check FSAB (or RSAB) squib circuit

CHECK: On the FSAB (or RSAB) connector (harness side), measure the resistance between FSAB (or RSAB) high and body ground

Resistance: Infinity

NG: Repair or replace the harness or the connector between the SRSCM and the FSAB (or RSAB).

OK: Go to step "3".

3. Check FSAB (or RSAB) squib.

PREPARATION
1. Turn ignition switch to LOCK.
2. Disconnect negative (-) terminal cable from the battery, and wait at least 30 seconds.
3. Connect the SRSCM connector and the FSAB (or RSAB) connector.




4. Connect the negative (-) terminal cable from the battery, and wait at least 30 seconds.

CHECK:
1. Turn the ignition switch to ON, and wait at least 30 seconds.
2. Clear the malfunction code stored in memory with the Hi-Scan Pro.
3. Turn the ignition switch to LOCK, and wait at least 30 seconds.
4. Turn the ignition switch to ON, and wait at least 30 seconds.
5. Using the Hi-Scan Pro, check for DTCs.
There is no DTC.

HINT: Codes other than these may be output at this time, but they are not relevant to this procedure.

NG: Replace the FSAB (or RSAB) module.

OK: Check the SRSCM.
The Inspection Procedure for RSAB is the same as FSAB.
