B1352

Detecting Condition:

CIRCUIT DESCRIPTION
The PAB squib circuit consists of the SRSCM and PAB. The squib is what causes the airbag to deploy when airbag deployment conditions are satisfied.

The above DTC's are recorded when PAB resistance too high or low is detected in the PAB squib circuit.

INSPECTION PROCEDURE

1. Preparation (See step "1" of DTC B1111/B1112 - Battery voltage too high/low "Inspection Procedure").
2. Check PAB resistance.

PREPARATION
Release airbag activation prevention mechanism on SRSCM side of airbag squib side.

Connect the dummy connector (0957A-38200)to PAB connector of the SRSCM connector side.




CHECK: Measure the resistance between PAB high (+) and PAB low (-).

1.7 Ohm < R < 2.3 Ohms

NG: Go to step "4".

OK: Repair or replace the harness between SRSCM and PAB.

3. Check PAB squib.

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




CHECK:
1. Turn ignition switch to ON, and wait at least 30 seconds.
2. Clear malfunction code stored in memory with Hi-scan.
3. Turn ignition switch to LOCK, and wait at least 30 seconds.
4. Turn ignition switch to ON, and wait at least 30 seconds.
5. Using Hi-scan, check DTC.

DTC is not output.

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

NG: Replace PAB.

OK: From the results of the above inspection, the malfunctioning part can now be considered normal.
