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 

Fig. 31: Checking Short To Battery Line 

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?
