How to Turn Off the Traction Control Light in a 2001 Jaguar 4 0

An illuminated traction control light in a 2001 Jaguar 4.0 is an indication that the ABS computer detects a problem with the traction control or anti-lock braking system. This could represent a current problem or a previous problem that has yet to be cleared from the ABS computers memory. An illuminated traction control light will remain on until the ABS computers memory is cleared and reset. In order to clear the computers memory and turn off the traction control light, a connection must be established between the ABS computer and an automotive scan tool. Once a connection is established, the memory can be cleared and the light will turn off automatically.

Instructions

1

Rotate the ignition switch to the OFF position in order to turn off the engine.

2

Locate the Jaguars diagnostic communications interface port, or DCIP. The DCIP is mounted just out of side, underneath the dashboard, below the steering wheel. The port has 16 connection pins and is the male end that connects to the female end of the scan tool.

3

Connect the female end of the scan tool to the male DCIP and turn the ignition switch to the ON position, then power on the scan tool.

4

Enter the make, model and year of your vehicle when prompted by the scan tool. Search the menus using the navigation keys on the scan tool and enter the ABS computer menu. Choose the option to read the trouble codes from the ABS computers memory. Write down the trouble codes that display on the screen. These alphanumeric codes have a very high diagnostic value and can explain why the code was triggered, should the light re-illuminate once the codes are cleared.

5

Choose the option to clear the codes from the computers memory. Once the memory is clear, the scan tool will indicate this on the main screen. Disconnect the tool and start the Jaguars engine. Confirm that the traction control light is now off.
