4. In the ABS Telltale test mode you can turn the instrument
panel indicators ON or OFF.
All indicators will turn ON when commanded on.
Does the ABS indicator turn on then OFF?
Replace the electronic brake control module (EBCM). Refer to
"Control Module References: " in Computer/Integrating
Systems.

Is the replacement complete?
1. Disconnect the instrument cluster and connect a test light
across the appropriate power and ground terminals.
2. With the test light OFF, repair the open in power or ground
circuit to cluster

3. With the test light ON, check the connector for poor
connection to cluster.
4. If OK, replace the instrument cluster. Refer to "Control

ABS Active Indicator Inoperative
Circuit Description
The instrument panel cluster (IPC) turns the ABS indicator on during the IPC bulb check for approximately 3 seconds
when the ignition switch is turned to the ON position. If the electronic brake control module (EBCM) sets a diagnostic
trouble code (DTC) the EBCM sends a class 2 message to the body control module (BCM) and the BCM sends a
class 2 message to the IPC to command the ABS indicator on.
Diagnostic Aids
• It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and
fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the
malfunction.
• Thoroughly inspect any circuitry that may be causing the complaint for the following conditions:
– Backed out terminals
– Improper mating
– Broken locks
– Improperly formed or damaged terminals
– Poor terminal-to-wiring connections
– Physical damage to the wiring harness
• The following conditions may cause an intermittent malfunction:
– A poor connection
– Rubbed-through wire insulation
– A broken wire inside the insulation
• If an intermittent malfunction exists refer to "Inducing Intermittent Fault Conditions: " in Wiring Systems.
