Could be an abs wheel speed sensor. bcm is correct. Gauges --- not sure,you need to fix one thing at a time. Scan bcm and repair codes first (traction control/abs sensor) what ever applies.

Where to find the traction control switch on a 2001 chevy cavalier


Doesn't have one ! The electronic brake control module turns it on an off when there is a problem ! Your light on ? DTC'S - diagnostic trouble codes stored .
Traction Off
The IPC illuminates the traction off indicator when the following occurs:
• The electronic brake control module (EBCM) inhibits the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The traction control system is disabled when the following occurs:
- For Chevrolet only, the shift lever is in FIRST (1) or SECOND (2) gear. The EBCM receives a class 2 message from the powertrain control module (PCM) indicating the gear position.
- For Pontiac and Oldsmobile only, the body control module (BCM) detects that the traction control switch is pressed (signal circuit is low). The EBCM receives a class 2 message from the BCM indicating the switch status.
- The BCM detects that the park brake is engaged (signal circuit is low) and that the engine is on. The EBCM receives a class 2 message from the BCM indicating the park brake status.
- The PCM detects certain malfunctions and is unable to perform torque reduction requests from the EBCM. The EBCM receives a class 2 message from the PCM indicating that traction control cannot be performed.
• The EBCM detects a malfunction in the traction control system. The IPC receives class 2 messages from the EBCM requesting illumination of both the service vehicle soon and traction off indicators.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.

How do i reset my traction control


Is your trac light lit ? If so it has a problem an till it is fixed , you can't reset it. Need to have it checked for DTC'S - diagnostic trouble codes .
If the ABS control module detects a malfunction, it will disable TCS and will command the BCM to turn the TRAC LED Off. The driver can also disable TCS, if desired, by depressing the TRAC switch. When the driver depresses the TRAC switch, the ABS control module will disable TCS and will command the BCM to turn the TRAC LED Off.
DTC C0276 TCM Traction Control Not Allowed
DTC C0275 or C0276
The TCM sends a serial data message to the electronic brake control module (EBCM) indicating that torque reduction is temporarily not allowed.
DTC C0550
DTC C0896
The electronic brake control module (EBCM) is required to operate within a specified range of voltage to function properly. During antilock brake system (ABS) and traction control system (TCS) operation, there are current requirements that will cause the voltage to drop. Because of this, voltage is monitored out of ABS/TCS control to indicate a good charging system condition, and also during ABS/TCS control when voltage may drop significantly. The EBCM also monitors for high voltage conditions which could damage the EBCM.

Traction Control System Indicator
TRAC OFF The instrument panel cluster (IPC) illuminates the TRAC OFF indicator when the following occurs:
?€¢
The electronic brake control module (EBCM) inhibits the traction control system due to a malfunction in the traction control system. The IPC receives a serial data message from the EBCM requesting illumination.


?€¢
The body control module (BCM) detects that the traction control switch has been pressed (signal circuit is low). The BCM sends a serial data message to the EBCM in order to disable traction control. The IPC receives a serial data message from the BCM requesting illumination. The BCM sends a serial data message to the radio in order to activate an audible warning.
you need to have the ( EBCM ) electronic brake control module checked fro codes !

Usually it's just a blown fuse that needs replacing or loose connection to the control unit (TGA MAN 26.410 fuse No. 19 is the one that relays current to the ZBR) worsed case scenario your control unit has crashed.

Mazdaspeed 3 08 Traction control light on


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Anti-lock brake system. TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module. TPMS Tire Pressure Monitor System
