YES : Go to Step 16.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the position light (LH) illuminates

normally.

STEP 16. Check the wiring harness between position light
(LH) connector A-18 (terminal 2) and front-ECU connector
A-07X (terminal 8).
Q: Is the wiring harness between position light (LH)

connector A-18 (terminal 2) and front-ECU connector

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the position light (LH) illuminates normally.

STEP 17. Check the position light bulb (RH).
(1) Remove the position light bulb (RH).
(2) Verify that the position light bulb (RH) is not damaged or

burned out.

STEP 18. Check position light (RH) connector A-36 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is position light (RH) connector A-36 in good condition?

YES : Go to Step 19.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the position light (RH) illuminates

normally.

STEP 19. Check the ground circuit to the position light
(RH). Test at position light (RH) connector A-36.
(1) Disconnect position light (RH) connector A-36 and measure

the resistance available at the wiring harness side of the
connector.

(2) Measure the resistance value between terminal 1 and

ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 21.
NO : Go to Step 20.

STEP 20. Check the wiring harness between position light
(RH) connector A-36 (terminal 1) and ground.
Q: Is the wiring harness between position light (RH)

connector A-36 (terminal 1) and ground in good
condition?
YES : Replace the position light socket (RH). Verify that the

position light (RH) illuminates normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the position light (RH) illuminates normally.
