COMBINATION METER ASSEMBLY
CHASSIS ELECTRICAL54A-33
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 vehicle 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 MPI system diagnosis code.
Q: Is MPI system diagnosis code P0500 set?
YES :
Refer to P.13A-186 <4G1> or P.13B-166
<4G6>.
NO : Go to Step 3.

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).

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?
