B1353

DTC B1353 - PAB Resistance Too Low (R < 0.4 ohm)




CIRCUIT DESCRIPTION
The PAB squib circuit consists of the SRSCM and PAB. If it causes the airbag to deploy when the airbag deployment conditions are satisfied.
The above DTCs are recorded when PAB resistance too high or low is detected in the PAB squib circuit.

INSPECTION PROCEDURE




1. Preparation.
1. Disconnect negative (-) terminal cable from the battery, and wait at least 30 seconds.
2. Remove the DAB module.
3. Disconnect connectors of PAB left and right side airbag, belt pretensioner and satellite sensor.
4. Disconnect connector of SRSCM.

CAUTION: Store the DAB with the front surface facing upward.

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.

NOTE: Before check the resistance, you have to insert shorting bar insert plastic attached diagnosis checker into SRSCM connector.




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

1.6 ohm < R < 2.8 ohm

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

OK: Go to step "3".

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 Scan Tool.
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 Scan Tool, check DTC.

NOTE: 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.
