STEP 3. Check combination meter connector D-03 and
vehicle speed sensor connector C-08 for loose, corroded
or damaged terminals, or terminals pushed back in the
connector.

Q: Are combination meter connector D-03 and vehicle

speed sensor connector C-08 in good condition?
YES : Go to Step 4.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. The speedometer should work normally.

STEP 4. Check the wiring harness between combination
meter connector D-03 (terminal 65) and vehicle speed
sensor connector C-08 (terminal 3).

NOTE: Also check intermediate connector E-111, E-114 and
joint connector (4) D-116. If intermediate connector E-111,
E-114 or joint connector (4) D-116 are damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection

.

Q: Is the wiring harness between combination meter

connector D-03 (terminal 65) and vehicle speed sensor
connector C-08 (terminal 3) in good condition?
YES : Go to Step 5.
NO : Repair the wiring harness. The speedometer should

work normally.

STEP 5. Check the speedometer by operating the
auto-cruise control system.
Q: Does auto-cruise control work normally?

YES : Replace the combination meter. The speedometer

should work normally.

NO : Replace the PCM. The speedometer should work

normally.

.

CIRCUIT OPERATION

• The tachometer power is supplied from the igni-

tion switch (IG) circuit.

• The tachometer detects the ignition signal control

via the PCM.

.

TECHNICAL DESCRIPTION (COMMENT)
The ignition signal may not be sent from the engine,
or there may be a malfunction in the power supply or
ground circuit.

.

TROUBLESHOOTING HINTS

• Malfunction of the combination meter (printed cir-

cuit board or speedometer and tachometer)

• The wiring harness or connectors may have

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

• Malfunction of the PCM

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

STEP 1. Check the tachometer by observing the other
meters.

Check to see that the speedometer, fuel gauge and water ther-
mometer operate normally.
Q: Do all other meters operate?

YES <other meters all operate> : Go to Step 2.
NO <one of the meters do not operate > : Refer to

INSPECTION PROCEDURE 5
