SRS code 2-1-2 850 1995

posted by  someone claiming to be Russ Bowman on  Tue Aug 19 10:17 CST 2003 [RELATED]

I got the fault code and replaced the airbag (my only option where I live (island Southeast Alaska) and tried to rest the light with no luck. I found there are other things to be checked, however neither me or my mechanic have any experience with this. Any suggestions?
Thanks
Russ Bowman

    SRS code 2-1-2 850 1995

    Here's what the book says:


    FAULT CODE 2-1-2, 2-2-2, 2-3-2, Or 2-4-2
    Conditions For Fault Code
    If OBD unit measures a resistance higher than is normal (1.8-
    2.5 ohms) for air bag igniter(s) and seat belt tensioners, a fault
    code will be set.

    Fault Symptom
    None, except illumination of SRS warning light.

    Fault Source
    There is an open circuit in SRS harness, connector or air bag module
    or seat belt tensioner.
    Corrective Action

    1) Turn ignition off. Disconnect battery negative cable.
    Disconnect connector to suspect air bag module or seat belt tensioner.
    Connect SRS Special Test Resistor (998 8695). See Fig. 8. Clear
    fault codes and try to retrieve fault codes. See SELF-DIAGNOSTIC
    SYSTEM. If fault code does not display within 15 seconds, replace
    suspect air bag module or belt tensioner. See REMOVAL & INSTALLATION.
    If fault code does display, go to next step.

    2) Carefully measure resistance between suspect
    module/tensioner connector and corresponding terminal in crash sensor
    connector. See WIRING DIAGRAMS. Resistance should be zero ohms. If
    resistance is infinity, there is an open circuit in wiring harness. Inspect
    wiring and connectors between crash sensor and suspect
    module/tensioner and replace as necessary.

    If fault code 2-1-2 is
    displayed, also check contact reel for short (Contact reel behind airbag module). Ensure steering wheel
    module is disconnected. Clear fault codes and perform SYSTEM OPERATION

    CHECK to verify repair and recheck for fault codes.

    Basically its saying you have an open circuit in either the steering wheel airbag module wiring or the driver's side seatbelt tensioner wiring (B-pillar). Inspect the wiring around the seat and see if you can find any broken or disconnected wires and reconnect them. Has the car been wrecked before? Does the driver's seatbelt harness work smoothly in and out? The seatbelt SRS tensioner is in the B-pillar on each side, the reel action should work smoothly. But it sounds like your problem is a wiring problem not necessarily a SRS Airbag or Tensioner. Hard to really analyse without looking at it. Good luck ........ Mike
