Low Tire Pressure Indicator Inoperative

Circuit Description
The Instrument Panel Cluster (IPC) turns the LOW TIRE Indicator ON for approximately 3 seconds when the ignition switch is turned to the RUN position during the IPC bulb check. If the EBCM sets a Diagnostic Trouble Code (DTC) the EBCM sends a class 2 message to the IPC to command the LOW TIRE Indicator on.

Diagnostic Aids
^ Perform a thorough inspection of the wiring and the connectors. Failure to carefully and fully inspect the wiring and the connectors may result in misdiagnosis, causing part replacement with a 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 Testing for Intermittent and Poor Connections.
