Refer to PREPARATION OF INSPECTION.

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 2 of BPT harness connector and chassis ground. 

Specification (voltage): Approximately 0 V 

Fig. 39: Checking Short To Battery Line 

4. Is the measured voltage within specification? 

YES  



Check the BPT Module.  

NO  



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

3. CHECK THE BPT MODULE 

1. Replace the Belt Pretensioner (BPT) with a new one. 



Refer to SEAT BELT PRETENSIONER .  

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 Belt Pretensioner (BPT)? 

YES
