Traction Control

ddddddd

Well to start off this is my first entry on this forum. I have a 1997 z28 Camaro 30th Anni. 4l60e Auto trany. The problem that i have is the traction control. My Camaro is very up to date no problems but at a dead stop it will barely bark the tires. I have been informed that if the traction control is on it dogs your car very badly. This car did not come with a button to switch on/off. If i power break it will burn all day long, but only in Drive. If i power brake in Over/Drive the tranny mount is garenteed to break everytime. The switch is suppost to be above the cd player. If you take the trim off their is wiring for it, so i went to orielys and they called GM and they had ordered the button for me. I got it a week later attached it, Nothing. I checked the fuse it is fine. I even pulled the fuse and it doesnt turn it off. Any Suggestions anyone???????????? Email me please.

Welcome!

If your TC is kicking in you will know it It interrupts fuel delivery for a second or so and then kicks back in. You would notice a stall like that and wouldn't mistake that for a loss of power.

I'm guessing if there was no switch you have no TC.

You may have some other issue with your trans.

Have you tried a poly trans mount?
They are much more durable than the stock rubber ones.

I have never heard of a Z28 with traction control coming with a switch. I have a friend with a 97 and TC and it does NOT have a switch. I don't think GM ever put one in a Z28. I think it only came in the Vette. If they never put one in it, adding a switch will not miraculously make it have one that works.

The reason pressing the brakes will make it burn is because the ABS over-rides the TCS system and disables it.

The only one I can think of to put a switch in it to make it disable the TCS is to put a switch in to activate the brake lights but I can tell you if you do, do not get caught by the police with it.

It doesn't matter what gear you have selected when you start off. It will always start in first. The computer controls the shifting. Putting it in OD will not make it more likely to break the trans mount. I would suggest the Energy Suspensions poly mount for an A4. Do not get a Prothane mount for an A4 or the vibrations will be unbearable.

An ASR equipped car should have a button to turn it off. The button is shown in the owner's manual (Camaros and Firebirds alike). I have never heard of a car having ASR from the factory that had no button. There is also a light on the dash that comes on with the bulb check at startup.
I always tell people "if there is no button, you don't have traction control".
You can also look for RPO code NW9.

I have a 97 30th Anniversary Z28 M6 and my car has ASR. There is in fact a switch above the radio next to the fog lamp switch.



ASR is on by default at startup and pressing the switch turns off ASR as indicated by the light on the instrument cluster.

I'm sorry I'm not positive about the TCS system on LT1 cars, but on LS1 cars, Z28's absolutely had the same switch shown in the above pics. I'm fairly certain it was introduced on some late 1997's as well, as proven above.

If you have traction control, you should get a "low trac" light when it engages (the outline for which is also visible in the above pic), and have a very noticeable reduction / stammering at launch if it is in fact the problem.

You have a couple of options to disable the TCS, pull the fuse and cover up the TCS off idiot light, or buy the logic module from SLP that simply reverses the operation (off by default, on when you turn it on).

I suspect, if you don't notice any of the above... that your car is simply a A4 / 2.73 car with decent 275 tires, and the fact is that cars equipped like that simply won't do a full fledged burnout on stickier street surfaces without torque-braking (and sometimes even with torque braking). If this is the case and you want the car to get off the line better, you're looking at upgrades - gears, stall, power adders, etc.

I wonder if it was a mid year change becuse A, I know of a 97 Camaro Z28 A4 with traction control and it definatley does not have that button, and B, I remember reading an article in a magazine complaining about the Z28 with tarction control not having a way to turn it off and not being able to burn the tires. I'll see if I can ger her to take a picture of her dash. Maybe the M6s got it and the A4s didn't.

The dash button is shown in the owner's manual, ever since they put ASR on the cars. It would not make sense not to have it. Anyone I have ever come across on the internet that had ASR had a button.

Does your car have a large plastic box sitting on top of the driver's side valve cover, with a cable connecting it to the throttle body quadrent? If it has traction control, you will have that box. If you do not have the box, you don't have traction control.

I know it doesn't make sense but it is true. She sent me a picture of hers but it has a CD changer control in front of the blank spot where the parts list shows the switch.

The RPO code is a defining feature- though I have never seen a car equipped with traction control that DIDN'T have the switch-

Another way to tell would be to check your rear axle- traction control had 4-channel ABS, sensors on each rear wheel- the non-equipped cars had 3-channel, and took rear wheel info off the top of the differential, on the ring gear-

i had a 95 z28 rear that had ASR and ABS and it had dual brake lines. not sure f they all did but this one did

Maybe the car has been altered.

[Jeff_in_Atl]

Maybe the car has been altered.

Nope. She bought it brand new and hasn't done anything to it. She is not a motor head.

Maybe it does not really have ASR then.
