Step 7. Check the wiring harness between
combination meter connector C-02 (terminal 39)
and ignition switch (IG1).

NOTE:

Also check junction block connector C-202 and
C-205 for loose, corroded, or damaged terminals, or
terminals pushed back in the connector. If junction
block connector C-202 and C-205 is damaged, repair
or replace the connector.

Q: Is the wiring harness between combination meter

connector C-02 (terminal 39) and ignition switch
(IG1) in good condition?

YES :

Retest the system.

NO :

Repair the wiring harness.

Step 8. Resistance measurement at combination
meter connector C-02 in order to the earth circuit
to the combination meter.

(1) Disconnect combination meter connector C-02,

and measure at the wiring harness side.

(2) Measure the resistance between terminal 1 and

earth.

OK: 2 ohms or less

(3) Measure the resistance between terminal 21 and

earth.

OK: 2 ohms or less

Q: Is the check result normal?

YES :

Go to Step 10.

NO :

Go to Step 9.

Step 9. Check the wiring harness between
combination meter connector C-02 (terminals 1
and 21) and earth.

Q: Are the wiring harness between combination meter

connector C-02 (terminals 1 and 21) and earth in
good condition?

YES :

Retest the system.

NO :

Repair the wiring harness.

Step 10. Retest the system.

Q: Is the check result satisfactory?

YES :

Intermittent Malfunction (Refer to GROUP
