Low Traction Indicator Inoperative

Low Traction Indicator Inoperative

Circuit Description
The instrument panel cluster (IPC) turns the LOW TRAC 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 DTC, the EBCM sends the IPC the command to turn the LOW TRAC 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 System for further diagnosis. Diagnostic Aids

Test Description





The numbers below refer to the step numbers on the diagnostic table.
2. This step verifies that the scan tool can turn ON and OFF all the indicator lamps in the instrument cluster.
4. This step verifies that the circuits going to the instrument cluster or the cluster is at fault.
