B1361

DTC B1361 DBPT RESISTANCE TOO HIGH (R ≥ 4.7 OHMS)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The BPTs squib circuits consist of the SRSCM and the BPTs. The SRSCM causes the airbag to deploy when the airbag deployment conditions are satisfied. The above DTCs are recorded when either BPT resistance is too high or low.

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 the connectors of the PAB, left and right side airbag,belt pretensioner and satellite sensor.
4. Disconnect the connector of the SRSCM.

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

DTC Detecting Condition:

2. Check the BPTs resistance.

[PREPARATION]
Release the shorting bar on the SRSCM side of the airbag squib side. Connect the dummy (0957A-38200) and dummy adapter (0957A-1C000) to the BPT connector of the SRSCM connector side.

NOTE: Before checking the resistance, you have to insert the shorting bar into the SRSCM connector.

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

1.8 ohms ≤ R ≤ 3.1 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 of 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 the Hi-Scan Pro, check for DTCs.
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 part can now be considered normal.
