This is a closeout for this SRS 232 issue. Here is what I found and did to troubleshoot this plaguing problem.

I took the car to Volvo for a complete diagnostic for $150USD where they said the SRS module was bad and for $1500+USD they would replace it. I asked why the 232 code and was told their test equipment was better than the under the hood DTC readout. 232 is the driver's side seat belt retraction device. Please read on......

I bought a used SRS module on eBay for $18USD. Unit was known good but upon batter reconnection SRS light came back on after about 20 seconds and remained on for duration. I went to a local "Pick and Pull" junkyard and got a used driver's side seat belt retraction device for $11USD, installed same but SRS light remained on. So I them took my original SRS module apart for closer inspection and found the old unit in good working order, i.e., circuit board, connectors and all other electronics in good working order. Once apart the SRS module could be resealed with ATV and reused but decided to just use the eBay one and keep the old one as a fishing weight. I was now certain that the issue was with the drivers side seat belt retract wire in the door frame to under the driver's side SRS metal panel. I traced the wires and found a bad orange SRS connector that I repaired. (I traced this wire before any other work but did not see the grounding clip!) Apparently when you disconnect one of the orange connectors there is a grounding clip inside the connector that grounds the plug if not fully connected or when the connectors are separated. I suspect this is a safety feature to prevent stay voltage to ground. After cleaning this plug and ensuring a good connector seat I double checked a good wire connection to the driver's side seat belt retraction device. I reconnected the battery and the SRS light came on for about 2-4 seconds on start up and went out normally.

I hope this helps someone else out there!
