STEP 1. Using scan tool MB991824, diagnose the CAN bus
line.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to "ON" position.
(3) Diagnose the CAN bus line.
Q: Is the check result satisfactory?
YES : Go to Step 2.
NO : Repair the CAN bus lines. (Refer to GROUP 54C,
Diagnosis-Can Bus Diagnostic Chart
completion, go to Step 3.
STEP 2. Using scan tool MB991958, read MFI diagnostic
trouble code.
Check if an MFI system DTC is set.
Q: Is the DTC set?
YES : Diagnose the MFI system by referring to GROUP
13A, MFI Diagnosis
− Diagnostic Trouble Code Chart
or GROUP 13B, MFI Diagnosis
−
. On
completion, go to Step 3.
NO : Go to Step 3.
Step 3. Retest the system.
Check to see that the engine coolant temperature gauge oper-
ates normally.
Q: Is the check result satisfactory?
YES : The procedure is complete. (If no malfunctions are
found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points-How to
Cope with Intermittent Malfunction
).
NO : Replace combination meter and then go to step 1.

COMBINATION METER TERMINAL CHECK
M1543026700010
Measure the voltage between terminals using a volt-
meter.
NOTE: The combination meter connector is fixed on the instrument panel directly, so you can not take mea-
surement by backprobing.
CAUTION
Never take a measurement at terminals 14 and
15. If you do this, the CAN bus lines will be
impaired.

1. Adjust the pressure of tires to the specified level (Refer to
GROUP 31, On-vehicle Service
CAUTION
Do not accelerate or decelerate suddenly during servicing
work.
2. Set the vehicle onto a speedometer tester and use wheel
chocks to hold the rear wheels.
3. To prevent the front wheel from moving from side to side,
attach tension bars to the tie-down hook, and secure both
