Instrument Cluster - RHD: Self-Test

The instrument cluster self-test will put the instrument cluster into its diagnostic mode. In this mode the instrument cluster can perform a self-diagnostic test that will confirm that the instrument cluster circuitry, the gauges and the indicators are capable of operating as designed. During the self-test the instrument cluster circuitry will position each of the gauge needles at various calibration points, illuminate each of the segments in the Vacuum-Fluorescent Display (VFD) units, and turn all of the indicators ON and OFF again.

Successful completion of the self-test will confirm that the instrument cluster is operational. However, there may still be a problem with the CAN or LIN data bus, the Powertrain Control Module (PCM) or Engine Control Module (ECM) (depending on engine application), the Totally Integrated Power Module (TIPM), the Controller Antilock Brake (CAB), the Occupant Restraint Controller (ORC), the compass module, the Wireless Ignition Node (WIN), the Steering Wheel Switch Module (SWSM), the Steering Control Module (SCM) or the inputs to one of these electronic control modules. Use a diagnostic scan tool to diagnose these components. Refer to the appropriate diagnostic information.

1. Begin the self-test with the ignition switch in the OFF position.
2. Depress the odometer/trip odometer switch button.
3. While still holding the odometer/trip odometer switch button depressed, turn the ignition switch to the ON position, but do not start the engine.
4. Release the odometer/trip odometer switch button.
5. The instrument cluster will simultaneously begin to illuminate all of the operational segments in the VFD units, and perform a bulb check of each operational bus message-controlled LED indicator. The VFD segments and LED indicators remain illuminated as each gauge needle is swept to several calibration points and back. If a VFD segment or an LED indicator fails to illuminate, or if a gauge needle fails to sweep through the calibration points and back during this test, the instrument cluster must be replaced.
6. The instrument cluster self-test is now completed. The instrument cluster will automatically exit the diagnostic mode and return to normal operation at the completion of the test. The instrument cluster self-test will be aborted if the ignition switch is turned to the OFF position, or if the ignition switch is turned to the START position.
7. Go back to repeat the instrument cluster self-test, if necessary. Refer to  1.
