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 EBTCM sets a
Diagnostic Trouble Code (DTC) the EBTCM 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
421906
- 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
Troubleshooting Procedures in Wiring System for
further diagnosis.
2. Checks if the scan tool can turn on and off all the
indicator lamps in the instrument cluster.
4. Checks if the circuits going to the instrument
Cluster or the cluster is at fault.
