Self-Diagnosis Mode of Combination MeterINFOID:0000000001704497
SELF-DIAGNOSIS MODE FUNCTION
• Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachom-
eter and fuel gauge).
• Self-diagnosis can check for odo/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) seg-
ment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warn-
ing lamp.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.

COMBINATION METERS
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” will indicate “0000.0”,
but the actual trip mileage will be retained. (The same applies for “trip B”.)
2. Turn ignition switch OFF.
3. While pushing the odo/trip meter switch (1), turn the ignition
switch ON.
4. Confirm that the trip meter displays “0000.0”.
5. Push the odo/trip meter switch at least 3 times. (Within 7 sec-
onds after the ignition switch is turned ON.)
6. All the segments on the odo/trip meter, and simultaneously the low-fuel warning lamp indicator illumi-
nates. At this time, the unified meter control unit is turned to self-diagnosis mode.
• M/T MODELS (1)
• A/T AND CVT MODELS (2)
NOTE:
• Check combination meter power supply and ground circuit when self-diagnosis mode of combination
meter does not start. Replace combination meter if normal. Refer to IP-11, "
Removal and Installation" .
• If any of the segments is not displayed, replace combination meter. Refer to IP-11, "
Removal and Instal-
lation" .
7. Each meter activates while pressing odo/trip meter switch. (At this time, the low-fuel warning lamp turns
off, low water temperature indicator lamp and high water temperature warning lamp turn on.)
NOTE:
If any of the meter and gages are not activated, replace combination meter. Refer to IP-11, "
Removal and
Installation" .

CONSULT-III Function (METER/M&A)INFOID:0000000001704498
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
SELF-DIAGNOSTIC RESULTS
Display Item List
NOTE:
“TIME” indicates the following.
• 0: Indicates that a malfunction is detected at present.
• 1-63: Indicates that a malfunction was dectected in the past. (Displays number of ignition switch OFF → ON
cycles after malfunction is detected. Self-diagnostic result is erased when “63” is exceded.)
DATA MONITOR
Display Item List
METER diagnosis mode Description
SELF-DIAG RESULTS Displays combination meter self-diagnosis results.
DATA MONITOR Displays combination meter input/output data in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
CONSULT-III display Malfunction Reference page
CAN COMM CIRC [U1000]Malfunction is detected in CAN communication lines.
CAUTION:
Even when there is no malfunction on CAN communication system, mal-
function may be misinterpreted when battery has low voltage (when main-
taining 7 - 8 V for about 2 seconds) or 10A fuse [No. 14, located in the fuse
block (J/B)] is removed.DI-19
VEHICLE SPEED CIRC [B2205]Malfunction is detected when an erroneous speed signal is input.
CAUTION:
Even when there is no malfunction on speed signal system, malfunctions
may be misinterpreted when battery has low voltage (when maintaining 7
- 8 V for about 2 seconds).DI-16
