STEP 2. Measure at combination meter connector C-101 in
order to power supply circuit to combination meter
(battery power supply).
(1) Disconnect combination meter connector C-101, and

measure at the wiring harness side.

(2) Turn the ignition switch to "LOCK" (OFF) position.

(3) Measure the voltage between terminal 1 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 4.
NO : Go to Step 3.

STEP 3. Check the wiring harness between combination
meter connector C-101 (terminal 1) and the fuse No.22.

NOTE: Also check intermediate connector C-29 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-29 is damaged, repair or
replace. Refer to GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between combination meter

connector C-101 (terminal 1) and the fuse No.22 in good
condition?
YES : Retest the system.
NO : Repair the wiring harness. Check that the

combination meter works normally.

STEP 4. Measure the voltage at combination meter
connector C-101 in order to power supply circuit to
combination meter (IG1 power supply).
(1) Disconnect combination meter connector C-101, and

measure at the wiring harness side.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 12 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 6.
NO : Go to Step 5.

STEP 5. Check the wiring harness between combination
meter connector C-101 (terminal 12) and the ignition
switch (IG1)

NOTE: Also check junction block connector C-211 and C-215
for loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If inspecting junction block connector
C-211 or C-215 is damaged, repair or replace. Refer to
GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between combination meter

connector C-101 (terminal 12) and the ignition switch
(IG1) in good condition?
YES : Retest the system.
NO : Repair the wiring harness. Check that the

combination meter works normally.

STEP 6. Measure the resistance at combination meter
connector C-101 in order to the ground circuit to the
combination meter.
(1) Disconnect combination meter connector C-101, and

measure at the wiring harness side.

(2) Measure the resistance value between terminal 3, 5 and

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 8.
NO : Go to Step 7.

STEP 7. Check the wiring harness between combination
meter connector C-101 (terminal 3 and 5) and ground.
Q: Is the wiring harness between combination meter

connector C-101 (terminal 3 and 5) and ground in good
condition?
YES : Procedure is complete. Retest the system.
NO : Repair the wiring harness. Check that the mode witch

and combination meter works normally.

STEP 8. Retest the system.

Q: Is the check result satisfactory?

YES : Go to Step 9
NO : Replace the combination meter.

STEP 9. Using diagnostic tool MB991958, diagnose the
CAN bus line.
(1) Connect diagnostic 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 10.
NO : Repair the CAN bus lines (Refer to GROUP 54C,

Diagnosis-Can Bus Diagnostic Chart

P.54C-15

). On

completion, go to Step 12.

STEP 10. Using diagnostic tool MB991958, read A/T
diagnostic trouble code.
Check if an A/T system or Engine (MPI) system DTC is set.

Q: Is the DTC set?

YES : Refer to GROUP 23A, Automatic Transmission

Diagnosis or GROUP 13A Engine (MPI)

− Diagnostic

Trouble Code Chart

P.23A-34

, or refer to Output

speed sensor system

P.23A-72

. On completion, go to

Step 12.

NO : Go to Step 11.

STEP 11. Check the speedometer
Use diagnostic tool MB991958 to enter simulated vehicle
speed.
(1) Connect diagnostic tool MB991958 to the data link

connector.

(2) Turn the ignition switch to "ON" position.
(3) Select "Interactive Diagnosis" from the start-up screen.
(4) Select "System Select."
(5) Choose "Meter" .
(6) Select "Simulated vehicle Speed Output."

OK: The speedometer shows that simulated vehi-
cle speed.

Q: Is the check result satisfactory?

YES : Go to Step 12.
NO : Replace the combination meter, then go to Step 12.
