No Posted by Ari [Email] ![]() ![]() In Reply to: Is the "off switch" upgrade for early 9000T TCS a cure-all, DS, Sun, 21 Oct 2001 23:05:05 Members do not see ads below this line. - Help Keep This Site Online - Signup |
All the TCS off switch does is turn off the TCS function - namely, turn the TCS off, and you can spin the wheels.
The 'problem' with TCS is that it is essentially a drive-by-wire system. That's true independent of the Off switch. If the TCS system thinks there is a sensor problem, it goes into a reduced power 'limp-home' mode. The TCS off switch has no effect on this, so even with the off switch, a sensor problem can cause the car to drop into limp-home.
The Off switch is an expensive deal for a '92. You need to replace the ECU with one from a '93 or '94, and those aren't cheap.
I wouldn't avoid a '92 just because of TCS. Most of the time the problems are due to dirty connections at the pedal sensor, or a bad vacuum valve, both of which are easy to fix. If you find a TCS equipped car you like, check the records to see if it has been in the shop chasing TCS ills. What, no repair records? Avoid that car, no matter what year it is.
Good luck!
