COMBINATION METER ASSEMBLY
CHASSIS ELECTRICAL54A-38
TECHNICAL DESCRIPTION (COMMENT)
The engine-ECU and its associated components, the
combination meter assembly, the wiring harness, or
the connector(s) may be defective.
TROUBLESHOOTING HINTS
•Malfunction of the vehicle speed sensor
•Malfunction of the engine-ECU
•Malfunction of the combination meter assembly
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
DIAGNOSIS PROCEDURE
STEP 1. MUT-II/III actuator test
(1) Connect the MUT-II/III to the diagnosis connector.(2) Use the MUT-II/III to enter simulated vehicle
speed.
Q: Does the speedometer show that simulated vehicle
speed?
YES :
Go to Step 6.
NO : Go to Step 2.
STEP 2. Check the output shaft speed sensor.
(MUT-II/III diagnosis code)
(1) Connect MUT-II/III to the diagnosis connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the automatic transmission system
diagnosis code.
Q: Is automatic transmission system diagnosis code
23 set?

COMBINATION METER ASSEMBLY
CHASSIS ELECTRICAL54A-49
DIAGNOSIS PROCEDURE
STEP 1. Check the fuel gauge circuit.
(1) Disconnect D-13 fuel gauge unit connector.
(2) Connect a test lamp (12 V − 3.4 W) via test
harness (MB991219) between the wiring harness
connector terminals 1 and 2.
(3) Turn the ignition switch to the "ON" position.
Q: Does the test lamp illuminate?
YES :
Go to Step 4.
NO : . Go to Step 2.
STEP 2. Connector check: Combination meter
connector C-06, fuel gauge unit connector D-13
Q: Is combination meter connector C-04, fuel gauge
unit connector D-13 in good condition?
YES :
Go to Step 3.
NO : Repair or replace the damaged
component(s).
STEP 3. Check the wiring harness between
combination meter connector C-06 (terminal 51)
and fuel gauge unit connector D-13 (terminal 1).

STEP 4. Voltage measurement at combination
meter connector C-04 to check the battery circuit
of power supply system to the combination
meter.
(1) Measure at combination meter connector C-04
without disconnecting the connector.
(2) Turn the ignition switch to “ON” position.
(3) Measure the voltage between terminal 9 and
earth.
OK: System voltageQ: Is the check result normal?
YES :
Go to Step 7.
NO : Go to Step 5.
STEP 5. Connector check: combination meter
connector C-04
Q: Is combination meter connector C-04 in good
condition?
YES :
Go to Step 6.
NO : Repair or replace the connector. Check to
see that all meters operate.

REAR WINDOW DEFOGGER
GENERAL INFORMATIONM1543000100319
Rear Defogger operation
The defogger relay turns ON if the defogger switch
built-in the A/C-ECU is turned ON when the ignition
switch is in the "ON" position. When the defogger
relay turns ON, power is supplied to the defogger
and the defogger is activated. The defogger comes
with a timer function that causes the defogger switch
to automatically turn OFF in about 11 minutes after
the defogger switch is turned ON.
TROUBLESHOOTINGM1543000701013
The rear window defogger is controlled by the
A/C-ECU. For troubleshooting, refer to GROUP 55-
Troubleshooting P.55-5.
