NOTE: Also check intermediate connectors D-28, D-111 and
F-10 for loose, corroded, or damaged terminals, or terminals
pushed back in the connector. If intermediate connector D-28,
D-111 or F-10 is damaged, repair or replace the damaged com-
ponent(s) as described in GROUP 00E, Harness Connector
Inspection

P.00E-2

.

Q: Is the wiring harness between taillight (LH) connector

G-16 (terminal 1) and front-ECU connector A-07X
(terminal 8) in good condition?
YES : No action is necessary and testing is complete.
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 taillight (RH) and side marker light (RH)
illuminates normally.

STEP 8. Check position light (LH) connector A-18 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is position light (LH) connector A-18 in good condition?

YES : Go to Step 9.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the position light illuminates

normally.

STEP 9. Check the ground circuit to the position light (LH).
Test at position light (LH) connector A-18.
(1) Disconnect position light (LH) connector A-18 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 : No action is necessary and testing is complete.
NO : Go to Step 10.

STEP 10. Check the wiring harness between position light
(LH) connector A-18 (terminal 1) and ground.
Q: Is the wiring harness between position light (LH)

connector A-18 (terminal 1) and ground in good
condition?
YES : No action is necessary and testing is complete.
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 illuminates normally.

STEP 11. Check the position light bulb (LH).
(1) Remove the position light bulb (LH).
(2) Verify that the position light bulb (LH) is not damaged or

burned out.

Q: Is the position light bulb (LH) in good condition?

YES : Go to Step 12.
NO : Replace the position light bulb (LH). Verify that the

position light (LH) illuminates normally.
