Hey everyone, I am new to this forum but I have been reading into a problem I am having with my 2001 Saab 9-3 Se convertible where my tcs button doesnt do anything. I know this year has a TCS but also at startup no light is tested. Is there some way to engage or disengage it? Or is the convertible wired not to go off? I found no fuses so I could not wire around it.
Thanks

Sounds like a burnt out bulb to me.

My car doesn't have TCS, so I don't have any test procedures, but I'm sure someone will chime in.

I'd pull the TCS button/switch out first and make sure you have the factory wires/plug going into it. I've seen cases in the past where people buy a used switch/button and put the switch in place for (1) to make folks think the option is there or (2) to use the switch for something else. For instance I have an extra fog light switch in my car that I use to activate/deactive power to my sub.

I have TCS on my '02. The default is that the TSC is always 'on' unless you manualy turn it off with the switch.

So if you have TSC (as suggested above, perhaps you only have the switch?), you should notice the car use the brakes and then the throttle to prevent wheel spin.

If you push the switch to disengage the TSC, you should get wheel spin and your dash light is burnt out.

On my car you can't turn off TCS unless you're going <35mph

I have done it below and above 35 as the manual stated and the ight isnt out because i drive aound with it after i push it but nothing changes so i think im going to have to pull the switch.

the tcs on my car will only turn off below around 35 but b/c of a problem with my e brake cable it locks up and sets off the abs and tcs but i dont mind that just dont like the warning lights that light up like a chirstmas tree

what years have tcs i have a 99 9-3 and have never seen a tcs light

i hear they started putting the button to turn the tcs on and off starting in the 2001's but idk if they had any sort of tcs in the older ones that were just automatic....like some of the 9000's did and also really screwed those cars up at the same time

My TCS recently failed to work after I had the dealer change the tire and wheel size. It had been at 15" and my spedo was running faster than I was going (was that way from the day I bought the car). After the dealer reset the wheel size the TCS was totally inoperable - no TCS, no warning light, nothing. Brought it back in and they ended up basically reprogrammed the SID since nothing else worked.

That might not be your problem, but something to verify.

I find it difficult to understand what wheel size has to do with it? The outer diameter of the tire would determine the rotations, not the wheel.

So if you properly size your tires to your wheels there should be no issue....right?

Is the dealer feeding you a line????

The wheel and tire size were both wrong thereby giving the SID the wrong circumference of tire and thus the spedo error. However, the dealer reset the sizes and it still didn't work so the mechanic basically reprogrammed the SID from square one telling it that the car had ABS, TCS, auto trans, etc. after that it worked. The mechanic was stumped as to why it didn't just work after the tire size change. He spent three hours tracking it down and even called Saabusa's tech line. They were no help so he reprogrammed it. And since I had just had the SID replaced (bad pixels) at the time they changed the tire size, there was no charge.
