Checking of CVT PositionBCS001MO
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transaxle body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps do not illuminate
when the selector lever is pushed toward the “R” position side
with the gear position remained in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.
8. Make sure transaxle is locked completely in “P” position.
9. When selector lever is set to manual shift gate, make sure man-
ual mode is displayed on combination meter.
Shift selector lever to “+” and “-” sides, and make sure set shift position changes.

COMBINATION METERS

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”).

SELF-DIAGNOSIS MODE FUNCTION

Odo/trip meter segment and shift indicator segment operation can be checked in self-diagnosis mode.

Meter/gauge can be checked in self-diagnosis mode.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with the “trip A” displayed, the mileage on the “trip A” will indicate
0000.0, but the actual trip mileage will be retained. (Trip same way for “trip B”.)
2. Turn ignition switch OFF.
3. While pushing the odo/trip meter switch, turn ignition switch ON again.
4. Make sure that the trip meter displays “0000.0”.

UNIFIED METER AND A/C AMPPFP:27760
System DescriptionBKS001SK

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter are integrated in the A/C auto
amp.

Unified meter and A/C amp. controls each operation for A/C
auto amp. For information regarding A/C control, refer to AT C -
24, "AIR CONDITIONER CONTROL" .

Unified meter and A/C amp. inputs necessary information for
combination meter from each unit by CAN communication and
so on.

And unified meter and A/C amp. outputs these signals using
communication line (TX, RX) between unified meter and A/C
amp. and combination meter.

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (with display unit) using CAN communication.

Other input signals are also sent to the ECM, TCM, BCM and display unit (with display unit) using CAN
communication.

The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor and data monitor).

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.
