TCS code & other issue
Hello folks,
I decided to be nice and let the wife drive halfway back when we were bringing the car back from the shop after a clutch replacement. As I followed her, I noticed the tail lights and rear side markers were flickering a bit as the car went over bumps. Possibly related, about halfway home the car threw the service abs, service traction control and threw TCS C1236. Possibly related?
The car has sat outside in the Pacific Northwest rain all winter. So a bit of corrosion could be a factor?
Any thoughts on where to start troubleshooting would be great! Thanks all

If my car sat out in that moisture that long I know the grounds under the hood for sure would need cleaned, and probably other places too. I have t clean those about 3 times a year because my fog-lights always stop working
So yeah, I would say check grounds for corrosion like you mentioned.

Since you didn't get a service active handling message it looks like your car is a 2000 or earlier car without active handling. That code indicates you have a low system voltage applied across the EBCM. First thing to check is the electronic ground connection at G108 over by the battery and G104 ground location. A poor ground will cause a reduction in voltage across a circuit. Also check the alternator to be sure it is producing sufficient voltage. If you had lights flickering that could be an indication of an alternator problem. On the other hand, since there are so many ground points lights flickering caused by a bad ground wouldn't necessarily indicate a bad ground was causing the EBCM problem.

I'll go out and scrub up my grounds. The alternator has been putting out a very steady 13.5-14v through the past couple drives (been watching it).
Thanks folks.
