SELF-DIAGNOSIS FUNCTION
Odo/trip meter, shift position indicator and ICC system display segments operation can be checked in self-
diagnosis mode.
Meters/gauges can be checked in self-diagnosis mode.
OPERATION PROCEDURE
1. Turn ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the self-diagnosis function is activated with the “trip A” displayed, only “trip A” display is reset.
2. Turn ignition switch OFF.
