Starting Combination Meter Self-Diagnosis Mode

NOTE:

Check combination meter power supply and ground circuits if self-diagnosis mode does not start. Refer to Diagnosis Procedure . Replace combination meter if power supply and ground circuits are found to be normal and self-diagnosis mode does not start. Refer to COMBINATION METER : Removal & Installation .
Combination meter self-diagnosis mode will function with the ignition switch in ON. Combination meter self-diagnosis mode will exit upon turning the ignition switch to OFF.

How to Initiate Self-Diagnosis Mode

Turn ignition switch OFF.
While pressing the trip reset switch , turn ignition switch ON.

Keep the trip reset switch for 1 seconds or more.
Press the trip reset switch at least 3 times. (Within 7 seconds after the ignition switch is turned ON.)
"Work instruction code" is indicated in the top portion of information display and self-diagnosis is started.
The mode switches in the order shown below each time the trip reset switch is pressed.

NOTE: If the trip reset switch is not operated for 20 seconds or more, the self-diagnosis mode is automatically cancelled.
