TCS ,and ABS( on the truck) lights on

Pull the plastic kick plate off on the lower left by the tilt column pedal. Check the pressure switches on the firewall. Pull the electrical connectors off one at a time and look for green corrosion on the connectors. Chances are water got in them and shorted the switches out.

 

MID 136 SID 89 FMI 2
this code is for the steering column sensor it is linked to the abs/traction control system
i believe usually a problem with a coroded wire, mine was a connector under the cab on inside of frame rail
MID 136 SID 4 FMI 14
sid 4 is your front drive axle, right side wheel, abs fault

 

Did you ever get your TCS light to go off , if so what was the fix , having the same issue with my Volvo , pretty much the same issue , spun the drive wheels entering a drive way and TCS light came on , truck is in the show , they are saying it needs a new ECU $4500 , any help would really be helpful.

 

Did you end up fixing the problem?

 

It is not your ecm I got the told the same thing replaced it paid for a new ecm and did the same problem only problem with me the TCS came on just cruising down the highway Nd it came on losing throttle and power it’s been at 6 shops and no one can figure out the problem

 

Hello gentlemen,
In reading your post on the TCS light I have a question / comment.
I just replaced my kingpin bushing and bearings as well as the tie rods and center link assembly. The TCS light never came on unless turned on by button on dash. AFTER the kp and tie rod work the TCS light is now on and I cannot turn it off. Could this some how be tied to a bad ABS sensor? Just thinking outside the box here, seeing how this problem did not show up until after the work. I also changed the inner and outer wheel bearings while in there. Figured to ask y'all. Hope that helps and any input is appreciated too.

Thanks,
Tee
