    B1941 41 RH primary crash sensor feed/return circuit open GO to DTC B1941.
    DTC B1941: RH PRIMARY CRASH SENSOR FEED/RETURN CIRCUIT OPEN- LAMP FAULT CODE 41


    The air bag diagnostic monitor periodically pulls the voltage at Pin C276-16, Circuit 617 (PK/O) low to verify the connection to Pin C277-24, Circuit 624 (Y/W). If the voltage at Pin C277-24, Circuit 624 (Y/W) does not pull low as a result of this test, the air bag diagnostic monitor will store in memory DTC B1941 and flash lamp fault code 41 on the AIR BAG indicator. If the connection between Pins C276-16, Circuit 617 (PK/O) and C277-24, Circuit 624 (Y/W) is later serviced, DTC B1941 will be stored in memory.
    Possible Causes
    Failure to get low voltage at Pin C277-24, Circuit 624 (Y/W) during the test can be caused by:
    • an open circuit in the wiring harness in either Circuit 617 (PK/O) or Circuit 624 (Y/W).
    • an open circuit inside RH primary crash sensor across Circuit 617 (PK/O) or Circuit 624 (Y/W).
    • a short to battery or ignition voltage in any of the Circuits 617 (PK/O), 619 (PK/W), 624 (Y/W), 625 (Y/LG).

This past week I did a heater core on my 2001 cavalier. Since the whole dash had to come out, obviously I had to take the airbags out. Upon putting it back together before installing bothe airbags I turned the ignition to make sure I didn't have any problem so I would not have to take it back...

Airbag code "51" 94 Merc Gr Marquis [ 1 Answers ]

I know nothing about airbags. I understand this code may be caused by a bad internal fuse causing a loss of short to ground. Where is this fuse? Is it possible for this loss of grounding to come from somewhere else? If so How do you troubleshoot this?
