For the last month my ABS light has been coming on. I got the following codes: 2-1-1(TCM Fault), 2-1-2(Short to voltage in #2, Shift Solenoid circuit), 2-1-3(No left rear wheel signal on moving off), 2-1-4 ? 1-4-1(Pedal signal faulty - Shorted to ground) 1-4-2(Stop lamp switch faulty)1-4-3-1(Kickdown switch faulty)I recently saw that someone had a similar problem but I have no idea what a TCM is or the best way to begin addressing these issues without going to the Volvo dealership

 

Archie i would say you have too many codes showing up for an actual problem with each circut. It sounds to me that you ABS module has gone bad. The contacts need to be repaired or you can buy a repaired module off Ebay that has already be repaired. See the DIY section in the front. That my guess.

 

TCM = Transmission Control Module

Should be one of the silver boxes under the cover of the big black plastic box under the hood over by the washer fluid reservoir.
