B1353

DTC B1352 PASSENGER AIRBAG RESISTANCE TOO HIGH (1ST STAGE)

DTC B1353 PASSENGER AIRBAG RESISTANCE TOO LOW (1ST STAGE)

DESCRIPTION
The PAB squib circuit consists of the SRSCM and PAB. It causes the SRS to deploy when the SRS deployment conditions are satisfied. The above DTC is recorded when the PAB resistance too high or low is detected in the PAB squib circuit.

Detecting Condition:

SPECIFICATIONS
PAB : 1.7 ohms ≤ R ≤ 2.3 ohms

INSPECTION OF CONNECTOR AND TERMINAL
1. Check all the connectors related to the DTC for contact condition visually.
2. Check the connector and the terminal.
1. Check the connector for connection securely.
2. Check the terminal for contact condition, deterioration, erosion and elasticity.

CAUTION: Do not deform the connector for revising contact.

3. Are confirmed trouble on the connector and the terminal?

YES - After repairing the trouble part, check whether DTC occurs or not.

NO - Check the PAB resistance.

CHECK PAB RESISTANCE
1. Preparation
1. Disconnect the negative (-) terminal cable from the battery and wait 30 seconds.
2. Remove the DAB module.
3. Disconnect the connector of the PAB, SAB, CAB, SIS, FIS and BPT.




4. Disconnect the SRSCM connector.




2. Check PAB resistance.

CAUTION: Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified tester.

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

1. Release the airbag activation prevention mechanism on SRSCM side of airbag squib side.
Connect the dummy (0957A-38200) and dummy adapter (0957A-2E100) to PAB connector of the SRSCM connector side.
Connect to the 2.0 ohms connector on dummy load.




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

Resistance: 1.7 ohms ≤ R ≤ 2.3 ohms

YES - Check the PAB squib.

NO - Replace the harness between the SRSCM and PAB.

CHECK PAB SQUIB
1. Preparation
1. Turn the ignition switch"LOCK".
2. Connect the PAB connector.
3. Connect the SRSCM connector.
4. Connect the negative (-) terminal cable from the battery, and wait for 30 seconds.

2. Check
1. Turn the ignition switch to "ON", and wait for at least 30 seconds.
2. Clear the malfunction code stored in the memory with the HI-Scan Pro.
3. Turn the ignition switch to "LOCK", and wait for at 30 seconds.
4. Turn the ignition switch to "ON", and wait for at 30 seconds.




5. Using Hi-Scan Pro, check the DTC.

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

6. There is no DTC.

YES - From the result of the above inspection, the malfunctioning part can now be considered normal.

NO - Replace the PAB.
