Diagnosis DescriptionINFOID:0000000003838726
SELF-DIAGNOSIS MODE
 Information display LCD segment 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 trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” is reset to “0000.0”.
(The same way for “trip B”.)
2. Turn ignition switch OFF.
3. While pressing the trip reset switch (1), turn ignition switch ON
again.
4. Make sure that the trip meter displays “0000.0”.
5. Press the trip reset switch at least 3 times. (Within 7 seconds
after the ignition switch is turned ON.)
6. The unified meter control unit is turned to self-diagnosis mode.
 The segment dots of the information display LCD (1) blink
alternately.
 Water temperature gauge and fuel gauge return to zero, simul-
taneously.
NOTE:
 Check combination meter power supply and ground circuit when the self-diagnosis mode of the combi-
nation meter does not start. Replace combination meter if abnormal.
 If any of the segments are not displayed, replace combination meter.

IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
