STEP 4. Check the wiring harness between combination 
meter connector C-03 (terminal 20) and multivision display 
connector C-10 (terminal 13).

• Check the communication lines for open circuit and short 

circuit.

NOTE: Also check intermediate connector C-17 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-17 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between combination meter 

connector C-03 (terminal 20) and multivision display 
connector C-10 (terminal 13) in good condition?
YES : Go to Step 5.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. 

STEP 5. Substitute a known good multivision display, and 
check the trouble symptom.
Check that no menus are active during driving.
Q: Is the check result normal?

YES : Replace the multivision display.
NO :  Replace the combination meter.

Inspection Procedure 5: The screen is not normal in the navigation mode. (The displayed position of 
the vehicle mark deviates.)

CAUTION

Before replacing the multivision display, ensure that the power supply circuit, the ground circuit, and 
the communication circuit are normal. (Check that the voltage is 10 V or more.)

.

COMMENTS ON TROUBLE SYMPTOM

There is a failure in the wiring harness between the 
combination meter and the multivision display, the 
GPS antenna, the respective connector(s), the com-
bination meter or the multivision display.

.

PROBABLE CAUSES

• Malfunctions of GPS antenna

• Malfunctions of combination meter

• Malfunctions of multivision display

• Damaged harness wires and connectors

STEP 1. Confirmation in MMCS service mode
Check the items below in the MMCS service mode. (Refer to 

P.54A-443

.)

•  Perform "Network/Connect Line Check" in the MMCS ser-

vice mode to check that the communication and wire con-
nection with the GPS are in good condition.

•  Perform "Vehicle Signal Check", and then check the status 

of the vehicle speed signal. 

•  Perform "Sensor Check", and then check the status of the 

vehicle speed sensor and the gyro sensor.

Q: Is the check result normal?

YES (OK for all) : Go to Step 6.
NO <GPS is not OK> : Go to Step 2.
NO <The vehicle speed sensor is not OK, or vehicle 
speed pulse does not increase after starting from a 
standstill> : Go to Step 3.
NO <Gyro sensor is not OK> : Go to Step 6.

STEP 2. GPS reception check
(1) Start the multivision display.
(2) Press the [INFO] button.
(3) Select [Vehicle Position].
(4) Check if the GPS signals are received.
Q: Is the check result normal?

YES : Go to Step 6.
NO :  Perform Inspection procedure 7 "GPS signal cannot 

be received."(Refer to 

P.54A-538

.) Then, go to Step 

6.

STEP 3. Check the speedometer.
Check whether the speedometer works normally.
Q: Does the speedometer work normally?

YES : Go to Step 4.
NO :  Diagnose the combination meter (Refer to 

Combination meter 

− Diagnosis 

P.54A-69

).

STEP 4. Check combination meter connector C-03 and 
multivision display connector C-10 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.
Q: Is combination meter connector C-03 or multivision 

display connector C-10 in good condition?
YES : Go to Step 5.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

.
