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.

NO :

Repair the wiring harness. The
speedometer should work normally.

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.
