ABS INDICATOR LAMP INOPERATIVE
Circuit Description
Battery voltage is supplied to the 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 20 or by the
shorting bar in the ABS module connector when it is dis-
connected from the module.
Diagnosis
This procedure checks 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.
Cause(s)
S A fuse has blown.
S The indicator lamp has burned out.S There is a corroded or broken connector terminal.
S There is a faulty ground connection.
S There is a broken wire in a wiring harness.
S The EBCM is faulty.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This test checks for any DTCs that may cause the
ABS indicator lamp to be inoperative.
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.

nal A13.
Is the repair complete?–System OK–
14Check the wiring harnesses and the connectors in
circuit LT GRN/BLK from the I/P cluster terminal A13
to terminal 20 of the EBCM connector.
Does the ohmmeter show the specified value?Go to Step 15Go to Step 16
15Repair the open or high resistance found.
Is the repair complete?–System OK–
16Check for continuity between terminal 19 of the ABS
connector and ground G106.
