DTC B1361 DRIVER BELT PRETENSIONER RESISTANCE TOO HIGHDTC B1362 DRIVER BELT PRETENSIONER RESISTANCE TOO LOW
DTC B1367 PASSENGER BELT PRETENSIONER RESISTANCE TOO HIGH
DTC B1368 PASSENGER BELT PRETENSIONER RESISTANCE TOO LOW
DESCRIPTION
The BPT squib circuit consists of the SRSCM and BPT. It causes the SRS to deploy when the SRS deployment conditions are satisfied. The above DTC is recorded when the BPT resistance too high or low is detected in the BPT squib circuit.
Detecting Condition:
SPECIFICATIONS BPT: 1.8 Ohm ≤ R ≤ 2.5 Ohm
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 BPT resistance.
CHECK BPT 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 BPT 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.
2. Connect the dummy (0957A-38200) and dummy adapter (0957A-1C000) to BPT connector of the SRSCM connector side.
Connect to the 2.0 Ohm connector on dummy load.
3. Measure the resistance between the BPT high (+) and low (-).
Resistance : 1 .8 Ohm ≤ R ≤ 2.5 Ohm
YES - Check the BPT squib.
NO - Replace the harness between the SRSCM and BPT.
CHECK BPT SQUIB
1. Preparation
1. Turn the ignition switch LOCK
2. Connect the BPT 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 BPT.
