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 Conditions and Poor Connections in Wiring Systems. |
