Diagnostic procedure for SRS code 2-3-2? 850 1995

posted by  someone claiming to be Malcolm Moore on  Mon Feb 5 13:40 CST 2001 [RELATED]

I have this unclearable DTC in my car and was wondering what the diagnostic procedure was to determine whether or not this part needed to be replaced. This is the left seat-belt tensioner, and the code I'm getting means that there is an open circuit or the capacitance is too low, according to the Volvo Pocket Data Book.

My question is, where should one check for resistance? At what resistance will this code trigger? What other parameters would trigger the DTC? Do mechanics even check for an open circuit or do they replace the part first and ask questions later?

Thanks for any and all help.

-Malcolm

    Volvo has a special tool to plug in in place of the seat belt pretensioner. The tool is conected and you try to clear the code. If the code clears, the seatbelt is replaced. If not, the wiring between the seat belt and SRS crash sensor has to be inspected. You really need the Volvo SRS manual and the tool. By the way, the tool is cheap, and can be used to diagnose seat belt pretensioners and both air bags. NEVER us an ohm meter to test the air bag or seat belt leads with the bags/belts conected. The meter can deploy the bags/belts. I strongly urge getting the VOLVO manual or a trained tech to look at this system.
