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 

P.54C-14

). On 

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 

P.13A-34

 or GROUP 13B, MFI Diagnosis 

− 

Diagnostic Trouble Code Chart 

P.13B-33

. 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 

P.00-6

).

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.

ON-VEHICLE SERVICE

SPEEDOMETER CHECK

M1543000900445

1. Adjust the pressure of tires to the specified level (Refer to 

GROUP 31, On-vehicle Service 

P.31-7

).

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 
ends to anchor plates.

4. To prevent the vehicle from moving, attach a chain or wire to 

the rear retraction hook, and make sure the end of the chain 
or wire is secured.

5. Check if the speedometer indicator range is within the 

standard values.
