NOTE: Prior to the wiring harness inspection, check
the junction block connector C-211, and repair if nec-
essary.

• Check the power supply line from the fusible link

(23) for open circuit and short.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

use Troubleshooting/inspection Service
Points

− How to Cope with Intermittent

Malfunction ).

NO :

Repair the wiring harness.

STEP 6. Retest the system.
Check that the tail lamps illuminate normally.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

use Troubleshooting/inspection Service
Points

− How to Cope with Intermittent

Malfunction ).

NO :

Replace the ETACS-ECU and register the
ID codes (Refer to

P.54A-39

).

DIAGNOSIS PROCEDURE

STEP 1. Connector check: F-04 <vehicles with
rear body> or F-23 <vehicles without rear body>
rear combination lamp (tail: LH) connector or F-
02 <vehicles with rear body> or F-19 <vehicles
without rear body> rear combination lamp (tail:
RH) connector

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Repair the defective connector.

STEP 2. Check the bulbs of the tail lamps.
Check the bulb of the lamp which does not illumi-
nate.

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Replace the bulb of the lamp which does not
illuminate.

STEP 3. Resistance measurement at the F-04
<vehicles with rear body> or F-23 <vehicles
without rear body> rear combination lamp (tail:
LH) connector or F-02 <vehicles with rear body>
or F-19 <vehicles without rear body> rear
combination lamp (tail: RH) connector.

(1) Disconnect the connector, and measure at the

wiring harness side.

(2) Check the resistance between the lamp

connector and body earth.

•

Resistance between F-04 rear combination lamp

(tail: LH) or F-02 rear combination lamp (tail:
RH) connector terminal No.5 and body earth
<vehicles with rear body>

•

Resistance between F-23 rear combination lamp

(tail: LH) or F-19 rear combination lamp (tail:
RH) connector terminal No.5 and body earth
<vehicles without rear body>

OK: Continuity exists (2

Ω or less)

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Go to Step 4.

STEP 4. Check the wiring harness from F-04
<vehicles with rear body> or F-23 <vehicles
without rear body> rear combination lamp (tail:
LH) connector or F-02 <vehicles with rear body>
or F-19 <vehicles without rear body> rear
combination lamp (tail: RH) connector terminal
No.5 to body earth.

NOTE: Prior to the wiring harness inspection, check
intermediate connector F-07, and repair if necessary.

• Check the earth wires for open circuit.

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Repair the wiring harness.

STEP 5. Connector check: C-218 ETACS-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Repair the defective connector.
