1. How to reset the ABS Light on a BMW
E36
The ABS light on a BMW E36 is designed to alert the driver to potential problems
with any part of the anti-lock braking system. The ABS computer continuously
monitors a number of sensors throughout the vehicle in order to ensure that the
anti-lock braking system is functioning properly at all times.
When the ABS computer detects a problem with the system, it stores a trouble code
in its internal memory and turns on the ABS light. An automotive scan tool with ABS
capabilities is the only tool that can properly clear the codes from the ABS computer
in order to turn off the ABS light. There is a way to reset it from XCAR360…
Instructions
1. Drive the vehicle onto a flat surface and shift the transmission into “Park” or first
gear (manual transmission). Turn off the engine and apply the parking brake. Turn
the ignition back to the “On” position so the dashboard has power.
2. Locate the vehicle’s diagnostic data port. This port is located underneath the
dashboard, just above the pedal area. It is approximately 2 inches wide, a half-inch
tall and made from black plastic.
3. Connect the scan tool’s data cable to the diagnostic data port. Power on the scan
tool and choose “ABS” from the scan tool’s main menu.
4. Choose “Trouble Codes” from the ABS menu. Select “Clear All Current and Stored
Trouble Codes” from the Trouble Codes menu. Wait a moment while the scan tool
clears the trouble codes.
5. Turn off the scan tool, unplug it from the vehicle and start the engine. Confirm
that the ABS light is no longer on.
2. Tips & Warnings
Automotive scan tools are small, portable computers that are used to perform
diagnostic tasks on modern vehicles. They can be rented or purchased from most
local auto parts stores and tool retailers.
