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.

Where is the anti theft system fuse located on 2001 Chevy cavalier


There is no fuse for the anti-theft system ! It receives it's voltage from the BCM . Do you know what a BCM is ? It is a Body control module .
The Passlock?"¢ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock?"¢ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock?"¢ System are as follows:
?€¢
The ignition lock cylinder and key


?€¢
The ignition lock cylinder case, including the Passlock?"¢ sensor


?€¢
The ignition switch


?€¢
The body control module (BCM)


?€¢
The security indicator on the instrument cluster


?€¢
The powertrain control module (PCM)


The body control module (BCM) contains the logic of the Theft Deterrent System. The BCM provides the battery positive voltage to operate the Passlock?"¢ sensor. The BCM also measures the voltage of the security sensor signal circuit. The voltage measured will indicate whether the Passlock?"¢ sensor has been activated and whether the resistance value from the sensor is a valid value or the tamper value. If voltage measured is in the valid range, the BCM compares this voltage, voltage code, to a previously learned voltage code. If the voltage codes match, the BCM sends a class 2 message containing a password to the powertrain control module (PCM). If the voltage codes do not match, or the voltage is in the tamper range, or there is a circuit fault, the BCM will not send the correct password to the PCM, and the vehicle will not start.
The body control system consists of a BCM and it's associated controls. Battery positive voltage is provided to the BCM from CLSTR fuse in the Fuse Block-left I/P. The module ground is wired to ground G201. The BCM is wired to the Class 2 serial data communication bus as well as discreet input and output terminals to control the functions of the vehicles body !
Now then Karen what problem is your vehicle having , no start an SECURITY light flashing or on solid ?
Now then

2002 chevy cavalier wont shift out of park unless I pull the bcm fuse


The shifter release solenoid is activated by the brake light switch. Check to see if the brake lights are working when you press the brake pedal. If not, that may be the reason why the shifter won't come out of park. You may need to replace or adjust the brake light switch. (It's located at the top of the brake pedal arm).

My factory cd player in my 2001 chevy cavalier wont read cd's so i put a factory cd player from another chevy cavalier and now the screen says locked


Most radios and cd players in cars require a code to get them operating again after they have been disconnected from the battery for an extended time. Hopefully a dealer could help you locate the code for that model.

Hello JJ, the problem areas to check would be:

1. headlight and panel dimmer switch.
2. interior door lamp control module
3. keyless entry module
4. door lock control module
5. door jam switches.
6. wiring problems.

Most of the time, it is the door switch on the drivers side, that is the problem.
I hope this information is helpful.
