SELF-DIAGNOSIS FUNCTION
 Odo/trip meter, A/T indicator and ICC system disp lay 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 “t rip A” displayed, only “trip A” display is reset.
2. Turn ignition switch OFF.

● Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly relate d to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in spite of the
