3. Is the measured resistance within specification? 

YES  



Check open circuit.  

NO  



Replace the Driver Airbag (DAB) module.  

3. CHECK OPEN CIRCUIT 

1. Measure resistance between the terminal 2 of DAB harness connector and the terminal 9 of 

SRSCM harness connector (A).  

2. Measure resistance between the terminal 1 of DAB harness connector and the terminal 10 of 

SRSCM harness connector (A). 

Specification (resistance): below 1 ohms

YES  



Check short circuit.  

NO  



Repair or replace the wiring harness between the DAB and the clockspring or between the 
clockspring and the SRSCM.  

4. CHECK SHORT CIRCUIT 

1. Measure resistance between the terminal 1 and 2 of DAB harness connector. 

Specification (resistance): ohms 

Fig. 69: Checking Short Circuit 

2. Is the measured resistance within specification? 

YES  



Go to next step.  

NO  



Repair or replace the wiring harness between the DAB and the clockspring or between the 
clockspring and the SRSCM.  

5. CLEAR THE DTC AND CHECK THE VEHICLE AGAIN 

Refer to CLEAR THE DTC AND CHECK THE VEHICLE AGAIN. 

DTC B1485 (2ND STAGE) PASSENGER AIRBAG RESISTANCE TOO HIGH; DTC B1486 (2ND 
STAGE) PASSENGER AIRBAG RESISTANCE TOO LOW 

DTC DESCRIPTION 

The Passenger Airbag circuit consists of the SRSCM and the Passenger Airbag (PAB) which has two squib 
circuits. The SRSCM sets above DTC (s) if it detects that the resistance of PAB squib is too high or low.
