DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

STEP 1. Measure at combination meter connector D-03 in
order to check the battery circuit of power supply system
to the combination meter.
(1) Disconnect combination meter connector D-03, and

measure at the wiring harness side.

(2) Measure the voltage between terminal 67 and ground.

• The voltage should equal approximately 12 volts (bat-

tery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 4.
NO : Go to Step 2.

STEP 2. Check combination meter connector D-03 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is combination meter connector D-03 in good

condition?
YES : Go to Step 3.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Check to see that all meters operate.

STEP 3. Check the wiring harness between combination
meter connector D-03 (terminal 67) and the battery.

NOTE: Also check intermediate connector D-28, junction block
connector D-217 and D-221. If intermediate connector D-28,
junction block connector D-217 and D-221 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 D-03 (terminal 67) and the battery in good
condition?
YES : There is no action to be taken.
NO : Repair the wiring harness. Check to see that all

meters operate.

STEP 4. Measure at combination meter connector D-03 in
order to check the ignition switch (IG1) circuit of power
supply system to the combination meter.
(1) Disconnect combination meter connector D-03, and

measure at the wiring harness side.

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

(3) Measure the voltage between terminal 62 and ground.

• The voltage should equal approximately 12 volts (bat-

tery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 7.
NO : Go to Step 5.

STEP 5. Check combination meter connector D-03 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is combination meter connector D-03 in good

condition?
YES : Go to Step 6.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection
