ABS Indicator Inoperative (Except North America)

ABS Indicator Inoperative (Except North America)

Circuit Description

Battery voltage is supplied to the antilock brake system (ABS) warning lamp with the ignition switch in the ON or START positions. The warning lamp can be activated only by the ABS control module internally supplying ground to terminal 44 or by the shorting bar in the ABS module connector when it is disconnected from the module.

This procedure inspects for a problem in the wiring, a faulty ground, a voltage supply problem, a burned out indicator lamp, or a contact problem in a connector.

Conditions for Setting the DTC

* A fuse has blown.
* The indicator lamp has burned out.
* There is a corroded or broken connector terminal.
* There is a faulty ground connection.
* There is a broken wire in a wiring harness.
* The electronic brake control module (EBCM) is faulty.

Test Description

The numbers below refer to the step numbers on the diagnostic table.
2. This test verifies an inoperative lamp condition.
3. This test checks for voltage on the lamp circuit.
4. This begins a series of tests of the circuit from the indicator lamp to the EBCM and ground.
19. This begins a series of tests of the voltage supply circuits that power the indicator lamp.
