TCS light

[Kevin Cooper]

My TCS light is on all the time. Pushing the on/off button has no effect. Initially it would come on after motor start. If I shut off after a few minutes and restarted it would stay out and the TCS would work. Now it is always off. I have a ECL on due to an O2 sensor failure that is about to be replaced. Any thoughts?

Thanks.

O2 replacment will fix the TCS light.

I also have this problem started today but mine would stay off after a few minutes and then followed by a clicking sound coming from behind the driver seat and the tech would drop off quickly like half a second a couple of times and then the TCS light stays on. Both of my O2 are only a few thousand miles old. My is a 93. any thoughts guys?

What is the process to resolder the relay. I saw a lot of people talking about this. Does anyone have picture for this process?

I don't have any pix when I was doing the resolder but here are 2 links. I think one of them has a exploded diagram show you where the relay is.

I did not now exactly which connection(s) needed solder as I was able to wiggle some of them so I resolder-ed all the connections and most of the connections took on(sucked in) more solder to make the connection stronger.
