SRS problem, need assistance.
Error as read via STAR:
"9103 - The resistance value in the ignition circuit containing component R12/3 (driver airbag ignition squib) is too high"
Having difficult figuring out how to fix this problem. R12/3 is the drivers air bag connection. However research shows that soldering the wire harness to the steering column module fixes this issue (lousy SCM connector). Removed the steering, verified the connector is seated properly. Removed the SCM and also verified the connector is seated properly. Rescanned and reset, problem still exists.
Dealer says there is no repair harness for the CL.
Has anyone soldered these wires before? My friend's CL has the same error code. Very common, but uncertain how to fix.

If all wiring is good... (you can check for continuity with ohmmeter- do not use test light and do not test the airbag as you might deploy it). Btw there is a service bulletin for this problem and there is no repair harness but there are updated connectors from the dealer (under the seat- you will have to remOve or tilt the seat).
If problem is still present...
It is possible that your airbag ignition (pyro) is going bad/ has separated inside. This is non- fixable.
Also it is possible that your airbag g- sensor in the center console is going bad.
Srs problems are a b1tch to troubleshoot.
