B1B76-RIGHT SIDE SATELLITE ACCELERATION SENSOR 2 INTERNAL





For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    The Occupant Restraint Controller (ORC) continuously communicates with the Right Side Impact Sensor 2 over the sensor signal circuit. The sensor communication and on board diagnostics are powered by the ORC signal.

  • Set Condition:

    This code will set, if the ORC and the Right Side Impact Sensor 2 do not establish and maintain valid data communications.


Possible Causes
  
(R18) SIGNAL CIRCUIT SHORTED TO BATTERY
  
(R18) SIGNAL CIRCUIT SHORTED TO GROUND
  
(R18, R20) RIGHT SIDE IMPACT SENSOR 2 CIRCUITS SHORTED TOGETHER
  
(R20) RIGHT SIDE IMPACT SENSOR 2 GROUND CIRCUIT OPEN
  
(R18) RIGHT SIDE IMPACT SENSOR 2 SIGNAL CIRCUIT OPEN
  
ORC, RIGHT SIDE IMPACT SENSOR 2
  



Diagnostic Test
