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)

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.

HEADLAMP
SERVICE SPECIFICATIONSM1542000300332
TROUBLESHOOTING M1542000701281
Features the headlamp automatic shutdown function
to avoid battery drain when the headlamps are left
on. The main features are as follows:
•Extinguishes automatically in three minutes if the
ignition switch is turned off with the lighting switch
on.
•Extinguishes in one second if the driver's door is
opened within that 3-minute period.
•If the headlamps are turned on with the ignition
switch off, the headlamps and tail lamps will
extinguish in three minutes after the driver's door
is opened or closed.
The headlamps are controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.
•Not using SWS monitor: GROUP 54B, SWS
Troubleshooting P.54B-38.
•Using SWS monitor: GROUP 54C, SWS

HEADLAMP AIMING
M1542000900538
PRE-AIMING INSTRUCTIONS
1. Inspect for badly rusted or faulty headlamp
assemblies.
2. These conditions must be corrected before a
satisfactory adjustment can be made.
3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not full, place a weight in luggage
room of the vehicle to simulate weight of a full
tank (0.8 kg per litre).
5. There should be no other load in the vehicle other
than driver or substituted weight of approximately
75 kg placed in driver's position.
6. Thoroughly clean the headlamp lenses.7. Place the vehicle on a level floor, perpendicular to
a flat screen 10 m away from the bulb
centre-marks on the headlamp lens.
8. Rock vehicle sideways to allow vehicle to assume
its normal position.
9. Bounce the front suspension through three (3)
oscillations by applying the body weight to hood
or bumper.
10.Four lines of adhesive tape (or equivalent
markings) are required on screen or wall:
(1) Position a vertical tape or mark so that it is
aligned with the vehicle centre line.
(2) Measure the distance from the centre-marks
on the headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or
mark on the screen is for reference of vertical
adjustment. Item Standard value Limit
