B1362

B1362 DBPT RESISTANCE TOO LOW OR SHORT (R <= 1.8OHM)

CIRCUIT DESCRIPTION

Circuit Description:

Wiring Diagram:

The BPT squib circuit consists of the SRSCM and BPT. It causes the airbag to deploy when the airbag deployment conditions are satisfied. The above DTCs are recorded when the BPT circuit is open or the BPT resistance too high or low is detected in the BPT squib circuit.

INSPECTION PROCEDURE

1. Preparation
1. Disconnect the negative (-) terminal cable from the battery and wait at least 30 seconds.
2. Remove the DAB module.
3. Disconnect the connectors of the PAB, left and right side airbags, belt pretensioners and SIS.




4. Disconnect the SRSCM connector.

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




2. Check the BPT resistance.

[PREPARATION]
Release the airbag activation prevention mechanism on the SRSCM side of the airbag squib side. Connect the dummy (0957A-38200) and dummy adapter (0957A-38300) to the BPT connector of the SRSCM connector side.

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.

[CHECK]
Measure the resistance between the BPT high (+) and the BPT low (-).

1.8 Ohms <= R <= 2.5 Ohms

[NG]-> Repair or replace the harness between the SRSCM and the BPT.

[OK]->

3. Check the BPT squib.

[PREPARATION]
1. Turn the ignition switch to LOCK.
2. Disconnect the negative (-) terminal cable from the battery, and wait for 30 seconds.
3. Connect the BPT connector.




4. Connect the negative (-) terminal cable to the battery, and wait for 30 seconds.

[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 30 seconds.
4. Turn the ignition switch to ON, and wait for 30 seconds.
5. Using Hi-Scan Pro, check the DTC. There is no DTC.

[HINT]
Codes other than these may be output at this time, but they are not relevant to this procedure.

[NG]-> Replace the BPT.

[OK]->
From the results of the above inspection, the malfunctioning pan can now be considered normal.
