Traction Control

**steven strickland** · 09-29-2007, 07:07 PM

I want to know if there is any way to by pass the traction control on a 98Z. Any help would be appreciated.

Thanks
Steve

That thread is good but doesn't completely answer the question.
If you don't have a TCS Switch than you don't have Traction Control.
All car's with TCS will have a single cable on the Throttle Body routed to the TCS Unit behind the Battery. If you have 2 cables on the Throttle Body then you Do Not have Traction Control.

How about checking RPO codes?

NW7 : TRACTION CONTROL - ELECTRONIC
NW9 : TRACTION CONTROL - ELECTRONIC

He asked how to BYPASS it.. I would imagine that would mean he knows he has it... SLP makes a module to reverse it so its off automatically instead of on.. I'm planning on getting it one of these days.. REALLY annoying hitting that button everytime I get in the car....

From the thread I posted above:
"Are you sure your car doesn't have traction control? Some of these cars were built without the switch-my car was.I bought my 02 new and the window sticker said traction control-but there was no switch installed in the dash-just a block off plate.I already had a service manual from my 98 that I traded in so I knew what to look for mechanically to verify the system was there.Look underneath at the back axle-if there is a wire going to both back wheels instead of just going into the middle of the rear axle-you have traction control and all you need is the switch to turn it on and off.If you have traction control but no switch-it will be on all the time-you can't turn it off and it comes on automatically when you start the car.Anyway they ordered a switch and installed it-service guy said it happened from time to time,I said no harm no foul. The ABS module looks different also-but the easiest way to tell is looking at the back axle."

I thought that answered the question "I want to know if there is any way to by pass the traction control on a 98Z.". I read the answer to be yes, a switch can be installed.

The SLP traction control logic module is here, a little over half way through the page: http://tbyrne.com/ls1/ls1transgears.html . I agree it's probably the better solution, I can see where having to hit a button every time could get annoying.

I had the SLP reversal...it's a very good buy.

I agree with most of this, although, all 98-02 Camaros and Firebirds have 4 channel ABS, which means a speed sensor on each end of the axle. 93-97 Camaros and Firebirds have 3 Channel ABS, which means 1 sensor for the whole rear. Having one or two wires running to the rear doesn't tell you wether you have ABS or not which was available in 3 channel and 4 channel systems.

Will that affect the ABS?

**bills98ta** · 10-01-2007, 05:10 PM

No, The ABS will work, but the gas pedal won't kick up any more, until you plug it back in...

**bills98ta** · 10-01-2007, 05:16 PM

It really sucks at the track, when you restart the car, & forget to shut it off... Won't spin in the water box !!!

98's also had 3 channel ABS.

Not mine, and 98 is when they switched over to 4 channel, which is why I have 2 speed sonsors on the rear axle.

**vetteemt** · 10-02-2007, 08:27 AM

My 98 SS has 4 channel also.

**0rion** · 10-02-2007, 01:04 PM

I would assume all traction control cars would have 4 channel rears but my 98 without traction control is a 3 channel.

**rossi1369** · 10-02-2007, 04:42 PM

All I did to bypass my TCS is unplug the fuse under the hood (not the fuse inside the car, since that is linked to other accessories)....havent had any problem.

Hmm, there must have been very few leftover rears from 97. My buds 98 has no traction control and he has a 4 channel rear.

You must not have 4 channel ABS

**0rion** · 10-02-2007, 07:08 PM

I'm gonna look and see if I can find some build numbers. I was under the impression a large number of 98's had the 3 channel rears but I've never seen any build numbers, just people on the boards buying and selling the rears out of their cars.

I am new on the site and have a 99 T/A and I have pulled the fuse under the hood before and my stupid TCS light shines in my face. If I unplug the motor will the light still come on?

Thanks!
