DTC B1363 DRIVER BELT PRETENSIONER RESISTANCE CIRCUIT SHORT TO GROUND
DTC B1369 PASSENGER BELT PRETENSIONER RESISTANCE CIRCUIT SHORT TO GROUND

DESCRIPTION
The BPT squib circuit consists of the SRSCM and DBPT. It causes the SRS to deploy when the SRS deployment conditions are satisfied. The above DTC is recorded when a short to ground is detected in the BPT squib circuit.

Detecting Condition:

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 squib circuit.

CHECK BPT SQUIB CIRCUIT
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 squib circuit
For the connector (on the SRSCM side) between the SRSCM and BPT, measure the resistance between the BPT high (+) and body ground.

Resistance : Infinity






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.
