1999 jag xj8 ... where is ABS control module/pump located on car? ABS light on .... traction control/stability control FAIL on ABS not functional via drive test car has traction control on / off switch [email protected]

When the Stabilitrak and Traction Control indicators come on and stay illuminated in your 2008 Saturn Outlook, it typically indicates a problem with the vehicle's stability control system. This system helps maintain control and stability during adverse driving conditions, such as wet or slippery roads. There are several potential causes for these warning lights, and it's essential to address the issue promptly to ensure your vehicle's safety and performance. Here are some common reasons for the warning lights to stay on:

1. Wheel Speed Sensor Issues: The Stabilitrak and Traction Control systems rely on information from wheel speed sensors to determine if a wheel is slipping or losing traction. If one of these sensors is malfunctioning or dirty, it can trigger the warning lights.
2. Faulty ABS Module: The Anti-lock Braking System (ABS) module is closely related to the stability control system. If there is a problem with the ABS module, it can affect the functionality of Stabilitrak and Traction Control.
3. Damaged Wiring: Damage to the wiring that connects the wheel speed sensors to the control module can disrupt the communication and trigger the warning lights.
4. Malfunctioning Control Module: The control module responsible for the stability control system can develop faults or errors over time.
5. Brake System Issues: Problems with the vehicle's braking system, including worn brake pads, can sometimes lead to issues with the Stabilitrak system.
6. Faulty Steering Angle Sensor: The steering angle sensor is part of the stability control system. A malfunction in this sensor can lead to warning lights.
7. Low Fluid Levels: Low brake fluid levels can trigger the warning lights, as the stability control system may interpret it as a potential issue with the braking system.

To diagnose and address the problem, you should take your Saturn Outlook to a qualified mechanic or a dealership. They can perform a diagnostic scan using specialized equipment to pinpoint the exact issue that is causing the warning lights to stay on. Once the problem is identified, they can recommend the necessary repairs or replacements.
It's important not to ignore these warning lights, as the stability control system is designed to enhance vehicle safety and performance, particularly in adverse driving conditions. Addressing the issue promptly will help ensure the continued safe operation of your vehicle.

This vehicle is equipped with the BOSCH 5.3 antilock braking system.
The vehicle is equipped with the following braking systems:
• Antilock Brake System (ABS)
• Dynamic Rear Proportioning (DRP)
• Traction Control System (ETS) (w/NW7)
• Traction Control System (TCS) (w/NW9)
• Vehicle stability enhancement system (VSES) You need to have vehicle checked for DTC'S diagnostic trouble codes , do you know what they are ? The traction control , ABS an stability control are all a function of the electronic brake control system .It also seams the power steering is controlled by the Antilock brake system.The Magnasteer® is controlled through the ABS module and varies the torque by adjusting the current flow through the actuator.
Your best place to start would be to have ABS module scanned for DTC'S . Codes would point you in right diagnostic direction .
The following components are involved in the operation of the above systems:
• Electronic Brake Control Module (EBCM), The EBCM controls the system functions and detects failures.
The EBCM contains the following components:
- System Relay, The system relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves and pump motor.
- Vent Tube, The vent tube, located in the EBCM, is an opening to the internal cavity of the EBCM. It allows ventilation of the EBCM internals.
• Brake Pressure Modulator Valve (BPMV), The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.

You have a problem with the abs an there is a code stored in the EBCM - electronic brake control module . It could be any number of thing's from a wheel speed sensor to a wiring problem or the control module or the modulation pump . As long as the light is on the ABS is deactivated . I would take it a qualified ASE certified repair shop that knows ABS systems

check the body control module under the dash

the stab light comes on if the battery is low because you are cranking the engine your aj26 v8 engine may have a common problem for cars up to that model/year with worn nicosil coated bores ie. low compression check the vin no. at your jag dealer you can get it started by removing the spark plugs and putting a egg cup of engine oil in to each of the cylinders the first thing to do is to check for fault codes using a obd code reader for a clue followed by a compression test

The brake pressure modulator valve is the heart of the abs and traction control systems. A fault in this part would cause the abs and traction control lights to come on as well as the service stability system. If this valve fails, the wheels could possibly lock up. If you were to experience the wheels locking up, you should pump the brakes to regain control over the vehicle.

That means that the EBTCM has detected a problem within the system.The message indicates that a malfunction exists in the stability enhancement feature.

EBTCM (Electronic Brake and Traction Control Module) is an electronic control module that controls and operates the Anti-Lock brake system, Traction Control System and Stability system. If this module detects a problem, it "asks" the cluster to inform you by displaying a warning message.

You should have your car scanned for trouble codes with a scan tool, the Tech2 scan tool is preferred because other scan tools may not communicate with the EBTCM modules.

Hope helps (remember to rate this answer).

abs modules work very hard. by the age of your car it seems that the abs module is packing up. the abs system has sensors on all four wheels that figures out braking, stability and control of the car when cornering. these do brake down over time and is part of the wear and tear side of things. you don't need to buy a new one. they do overhaul these things for much cheaper. your car magazines should advertize the fixing of these things or contact a scrapyard for a secondahand one. check if the abs sensors are not faulty and replace them. do not go to the agents, they will rip you off. good luck

welcome to Jag ownership. I hope you have deep pockets,

The most likely root cause of the problem has been determined, and its step by step fix is also detailed if you have the skills to do that yourself. See the excellent detailed website posting by Dan Jensen on the Jag-lovers.org site forums.jag-lovers.org under avsn.php?1169101j41 . He describes what goes wrong in the $2800 ABS control electronic board, and that simply re-soldering a few heavy wires to the board will fix the trouble. But it requires some mechanical work to get that module out, and then some more work to saw the plastic case apart to get to that circuit board. - Best regards - MHH
