Enhanced Traction System Warning Light (TRAC OFF)

The Enhanced
Traction System
warning light may
come on for the
following reasons:


If you turn the system off by shifting to SECOND (2)
or FIRST (1), the warning light will come on and stay
on. To turn the system back on, shift to THIRD (3) or
AUTOMATIC OVERDRIVE (
). See “Enhanced
Traction System” in the Index.


If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. Adjust your driving accordingly.


The warning light will come on when you set your
parking brake with the engine running, and it will
stay on if your parking brake doesn’t release fully.
If the transaxle shift lever is in any position other
than FIRST (1) or SECOND (2) and the warning
light stays on after your parking brake is fully
released, it means there’s a problem with the system.


If the traction control system is affected by an
engine-related problem, the system will turn off
and the warning light will come on.

The chime is going off to alert you to the charging system problem, have it tested.

StabiliTrak Indicator Light: If the warning light does not come on then, have it fixed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly.

This light will also flash when the StabiliTrak system is active. If the StabiliTrak system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service.

The traction control part of StabiliTrak can be turned off by pressing and releasing the StabiliTrak button if both systems (traction control and StabiliTrak) were previously on. To disable both traction control and StabiliTrak, press and hold the button for five seconds.

Traction control and StabiliTrak can be turned on by pressing and releasing the StabiliTrak button if not automatically shut off for any other reason.

When the TCS or StabiliTrak system is turned off, the StabiliTrak light and the appropriate TCS off or StabiliTrak off message will be displayed on the DIC to warn the driver. Your vehicle will still have brake-traction control when traction control is off, but will not be able to use the engine speed management system.

If the StabiliTrak and/or Traction Control are not operating properly, I encourage you to take your vehicle in for inspection. A certified technician will be able to offer a more accurate diagnosis.

No.
The brake warning light could be telling you there is a problem with the hydraulic brake system or the parking brake.
The trac off light is saying there is a problem with the brakes or engine and the traction control system is disabled.

You either have a problem with your engine control system, the traction control system, or you are not in the correct gear. See the explaination below. This is from the 2000 Chevrolet Cavalier Owner's Manual.

TRAC-OFF LIGHT

... If you turn the system off by moving the shift lever

to FIRST (1) or SECOND (2), the warning light will

come on and stay on. To turn the system back on,

move the shift lever back to a position other than

FIRST (1) or SECOND (2). The warning light

should go off. (See "Enhanced Traction System"

in the Index for more information.)

The warning light will come on when you set your

parking brake with the engine running, and it will

stay on if your parking brake doesn't release fully.

If the transaxle shift lever is in any position other

than FIRST (1) or SECOND (2) and the warning

light stays on after your parking brake is fully

released, it means there's a problem with the system.

If the traction control system is affected by an

engine-related problem, the system will turn off

and the warning light will come on.

If the Enhanced Traction System warning light comes

on and stays on for an extended period of time when the

transaxle shift lever is in any position other than FIRST
(1) or SECOND (2) your vehicle needs service.

T/C light = Traction Control

Could be something going on with a wheel speed sensor. You'll have to have the ABS/TCS controller scanned for any stored trouble codes to see why the controller is turning on the light. The code(s) might help you to determine what part of the system is faulting. You'll have to take it to a shop that has a high end scan tool.

If the TC light is on, chances are there is a trouble code set and stored in the computer. You need to determine what the code is. If you take the car to a nationally recognized parts store, most will scan the computer for free, so there is no money out of pocket for you.


Actron also makes a ABS code checker called BrakeScan. Don't know how good it is, but it might be good for a DIY person.

EST - Enhanced Traction System

This light should come on briefly as you start the engine.
When the warning light is on, the system will not limit wheel spin.
There should be a button to turn it on or off, for the system to be working the light should be off, if the light is just staying on you need to have it services.
Hope this was very helpful.

hi Deborah.
this is all i could find out from the internet.
ABS and Trac OFF usually indicate a dirty or faulty ABS wheel sensor. You'll have to scan for the codes to see why the check engine light is on.
the abs and trac is the wheel speed sensor, you will probably have to replace the hub.
Have you already checked your owners manual for troubleshooting? If not, page 3-35 has the section about your "Trac Off" message.

"If there's a brakesystem problem that is specifically
related to tractioncontrol, the tractioncontrol
system will turn off and the warning light will come
on. If your brakes begin to overheat, the traction
controlsystem will turn off and the warning light will
come on until your brakes cool down...
If the tractioncontrolsystem warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service."

not sure if this helps you out but its all i could find out.
sorry if its of no help to you.

Sometimes it's a complaint with the ABS braking system. If it comes on and you have no other problems and stays on for while, check your brakes. I have had this issue before and had my brakes replaced. They were worn but for some reason were not squeaking.
