DIAGNOSIS
Required Special Tools:
• MB991223: Harness Set
• MB991958: Scan Tool (MUT-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: MUT-III USB Cable
• MB991911: MUT-III Main Harness B (Vehicles without
CAN communication system)
STEP 1. Using scan tool MB991958, read the MFI system
diagnostic trouble code.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to "LOCK" (OFF) position before connect-
ing or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the MFI system diagnostic trouble code.
Q: Is MFI system diagnosis code output?
YES : Refer to GROUP 13A, MFI diagnosis
NO : Go to Step 2.
STEP 2. Check the speedometer operation.

STEP 3. Check the combination meter (tachometer) ground
circuit at combination meter connector C-05.
(1) Disconnect combination meter connector C-05.
(2) Measure the resistance between terminal 13 and ground.
• The measured value should be 2 ohms or less.
Q: Does the measured resistance value correspond with
this range?
YES : Go to Step 6.
NO : Go to Step 4.

STEP 4. Check combination meter connector C-05 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is combination meter connector C-05 in good
condition?
YES : Go to Step 5.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. The tachometer
should work normally.
STEP 5. Check the harness wires between combination
meter connector C-05 (terminal No.14) and ground.
Q: Are the harness wires between combination meter
connector C-05 (terminal No.14) and ground in good
condition?
YES : There is no action to be taken.

STEP 6. Check the ignition signal input circuit at
combination meter connector C-04.
(1) Disconnect combination meter connector C-04.
(2) Start the engine and run at idle.
(3) Measure the voltage between terminal 24 and ground by
back probing.
The measured value should be approximately 10 volts.
Q: Does the measured voltage correspond with this range?
YES : Repair or replace the combination meter
(printed-circuit board or speedometer and
tachometer).
NO : Go to Step 7.
STEP 7. Check combination meter connector C-04 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is combination meter connector C-04 in good
condition?
YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. The tachometer
should work normally.
STEP 8. Check the harness wires between combination
meter connector C-04 (terminal No.24) and ignition switch
(IG1).
