Gauges Self-Diagnostic Function (2016 2017): Notes

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

• The indicator drive circuit check.
• The switch input check.
• The beeper drive circuit check.
• The LCD check.
• The gauge drive circuit check (engine coolant temperature gauge, fuel gauge, speedometer, and tachometer).
• The communication line check (of the body controller area network (B-CAN) communication line, the fast controller area network (F-CAN) communication line, and the other communication line between the gauges).

NOTE:  Indicators are also controlled via the communication lines.
