TSB Revision

CHASSIS ELECTRICAL

54A-65

TROUBLESHOOTING HINTS

• Malfunction of the combination meter (printed-cir-

cuit board or speedometer and tachometer)

• Damaged wiring harness or connectors

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

.

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 

P.00E-2

. Check to see that all meters operate.
