Hi Guys,
Tonight I received a PSM Faulty Workshop msg on my 2004 CTT. I picked the car up today after having it shipped to me seeing I relocated approx 12 weeks ago. The car has sat and started, resulting in a flat battery. The shipping company jumped the car when they moved it and they had to jump start it again today before I picked it up. Luckily I drove it 90mins to home and seems like the battery is back to normal. After driving to get some fuel tonight, the PSM Fault Workshop code came up on the screen.

Could this have anything to do with the battery going flat? I appreciate your thoughts and where I could begin to look at fixing this issue.

Thanks

 

OP - Yes it can. Many folks get PSM or drive system faults with a sub-par battery. Mine got the drive system fault and some other spurious error. Fully charge or replace battery (if battery tests out wonky). That would be my first step.

 

Battery changed and all seems back to normal. Thanks
