Mitsubishi L200. Manual - part 749

MITSUBISHI MULTI COMMUNICATION SYSTEM (MMCS)

CHASSIS ELECTRICAL

54A-363

Inspection Procedure 5: The screen is not normal in the navigation mode. (The own vehicle mark is 
dislocated.) <Except vehicle for RUSSIA>

CAUTION

Before replacing the multivision display, ensure 
that the power supply circuit, the earth 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 vehi-
cle speed sensor or the multivision display.

PROBABLE CAUSES

• Malfunctions of GPS antenna

• Malfunctions of multivision display

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

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

P.54A-305

.)

•  Perform "Network/Connect Line Check" in the 

MMCS service mode to check that the communi-
cation and wire connection 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 "GPS signal 
cannot be received" (Refer to 

P.54A-370

.), 

and then go to Step 6.

STEP 3. Check the speedometer.
Check whether the speedometer works normally. 
(Refer to 

P.54A-87

.)

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Diagnose the combination meter. (Refer to 
Combination meter 

− Troubleshooting 

P.54A-46

.)

STEP 4. Connector check: C-127 joint connector, 
C-170 multivision display connector

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Repair the defective connector.

STEP 5. Check the harness wire between D-127 
joint connector terminal No.17 and C-170 
multivision display connector terminal No.13.

• Check the communication lines for open circuit 

and short circuit.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the wiring harness.

STEP 6. Check of the troubles
Drive the vehicle for some time with the GPS signals 
being received, and check if the own vehicle mark is 
dislocated.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Replace the multivision display.

Inspection Procedure 5: The screen is not normal in the navigation mode. (The own vehicle mark is 
dislocated.) <Vehicles for RUSSIA>

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM
If the own vehicle mark is dislocated, there is a fail-
ure in the wiring harness between the vehicles speed 
sensor and the multivision display, the GPS antenna, 
the respective connector(s), the vehicles speed sen-
sor or the multivision display.
NOTE: If the vehicle speed signal has a problem, the 
speedometer of combination meter will be affected. 
Confirm if the speedometer of combination meter 
works normally at the abnormal state to customers.

PROBABLE CAUSES

• Malfunctions of GPS antenna

• Malfunctions of vehicles speed sensor

• Malfunctions of multivision display

• Damaged wiring harness and connectors
