Self-Diagnostic Function: Notes

The gauge control module has a self-diagnostic function which consists of the following checks:

• The indicator drive circuit check.
• The beeper drive circuit check.
• The ambient meter color variation check.
• The switch input test.
• The multi-information display (MID) check.
• The gauges drive circuit check (tachometer).
• The communication line check of the B-CAN (body-controller area network) communication line and the F-CAN (fast-controller area network) communication line between the gauges.
  NOTE: Indicators are also controlled via the communication lines.
