HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER

The vehicle speed signal and the memory signals from the meter memory circuit are processed by the
combination meter and the mileage is displayed.

Depressing the odo/trip meter switch toggles the mode in the following order.

The odo/trip meter display mode toggling and trip display resetting can be identified by the amount of time
that elapses from pressing the odo/trip meter switch to releasing it.

When resetting with trip A displayed, only trip A display is reset (The same way for “trip B”).

CONSULT-II Function (METER A/C AMP)BKS001SO
CONSULT-II performs the following functions communicating with the unified meter and A/C amp.
CONSULT-II BASIC OPERATION
Refer to GI-34, "CONSULT-II Start Procedure"
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
SELF-DIAGNOSTIC RESULTS
Display Item List
“TIME” indicates the condition of the self-diagnostic results judged by each signal input.

Normal: In case of operating properly at the present in spite of having malfunction in the past, then “TIME”
indicates “1-63”.

Malfunction: Soon after detecting malfunctions by self-diagnoses or current malfunction, “0” is indicated.
After returning to normal condition, every time when ignition switch is turned to “OFF” from “ON”, time will be
added like “1”→“2”→“3”···“63”, and when the key operation is performed 64 times, the result of the self-diag-
noses will be erased. And if any malfunction is detected again, “0” will be indicated.
