2. CHECK SHORT TO BATTERY LINE

1. Connect the battery negative cable to the battery.

2. Turn the ignition switch to ON.

3. Measure voltage between the terminal 1 of PAB harness connector and chassis ground. (PAB stage

1)

4. Measure voltage between the terminal 3 of PAB harness connector and chassis ground. (PAB stage

2)

Specification (voltage): Approximately 0 V

5. Is the measured voltage within specification?

YES



Check the PAB Module.

NO



Repair the short to battery line circuit on wiring harness between the PAB and the SRSCM.

3. CHECK THE PAB MODULE

1. Replace the Passenger Airbag (PAB) with a new one.



Refer to AIR BAG MODULE (PASSENGER SIDE) .

2. Install the DAB module and connect the DAB connector.

3. Connect the connectors of the PAB, SAB, CAB, BPT, FIS and SIS.

4. Connect the SRSCM connector.

5. Connect the battery negative cable to the battery.

6. Connect a Hi-Scan (Pro) to the data link connector.

7. Turn the ignition switch to ON and check the vehicle again.

Does Hi-Scan (Pro) indicate any DTC related to PAB?

Refer to TERMINAL & CONNECTOR INSPECTION.

INSPECTION PROCEDURE

1. PREPARATION

Refer to PREPARATION OF INSPECTION.

2. CHECK BPT RESISTANCE

1. Connect the Dummy and the Dummy Adapter on BPT harness connector.

2. Measure resistance between the terminal 3 (2) and 4 (1) of SRSCM harness connector (B).

Specification (resistance): 1.6-4.7

CAUTION: Never attempt to measure the circuit resistance of the airbag module

(squib) even if you are using the specified tester.
