Also check joint connector C-21 <LH drive vehicles> 
or C-101 <RH drive vehicles>, intermediate connec-
tor B-27 and C-124 for loose, corroded, or damaged 
terminals, or terminals pushed back in the connector. 
If joint connector C-21 <LH drive vehicles> or C-101 
<RH drive vehicles>, intermediate connector B-27 or 
C-124 are damaged, repair or replace the connector.

Q: Is the wiring harness between combination meter 

connector C-01 (terminal 12) and vehicle speed 
sensor connector B-04 (terminal 3) in good 
condition?
YES : 

Replace the combination meter. The 

speedometer should work normally.

TECHNICAL DESCRIPTION (COMMENT)

Ignition signal may not be received from the 
engine-ECU, or the combination meter assembly, the 
wiring harness, or the connector(s) may be defective.

TROUBLESHOOTING HINTS

• Malfunction of the combination meter assembly

• Malfunction of the engine-ECU

• The wiring harness or connectors may have 

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

DIAGNOSIS PROCEDURE 

STEP 1. Check the other meters.

Check to see that the speedometer, fuel gauge 
and water thermometer are operating 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
