STEP 12. Check the battery power supply circuit to the
daytime running light relay. Measure the voltage at daytime
running light relay connector A-23X.

CAUTION

The top and bottom of the daytime running light relay are
difficult to identify. Prior to inspection, confirm the triangle
mark on the relay box.
(1) Disconnect daytime running light relay connector A-23X

and measure the voltage available at the relay box side of
the connector.

(2) Measure the voltage between terminal 1 and ground, and

also between terminal 4 and ground.

OK: The voltage should measure approximately 12
volts (battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 14.
NO : Go to Step 13.

STEP 13. Check the wiring harness between daytime
running light relay connector A-23X (terminal 1 and 4) and
fusible link (36).

• Check the power supply line for open circuit.

Q: Is the wiring harness between daytime running light

relay connector A-23X (terminal 1 and 4) and fusible link
(36) in good condition?
YES : The trouble can be an intermittent malfunction (Refer

to GROUP 00

− How to Cope with Intermittent

Malfunction

P.00-15

).

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 daytime running lights illuminate normally.

STEP 14. Check ETACS-ECU connector C-312 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-312 in good condition?

YES : Go to Step 15.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

STEP 15. Check the wiring harness between daytime
running light relay connector A-23X (terminal 2) and
ETACS-ECU connector C-312 (terminal 10).

• Check the communication wires for open circuit.

Q: Is the wiring harness between daytime running light

relay connector A-23X (terminal 2) and ETACS-ECU
connector C-312 (terminal 10) in good condition?
YES : Go to Step 16.
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 daytime running lights illuminate normally.

STEP 16. Retest the system.
Q: Does the daytime running lights illuminate in good

condition?
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

P.00-15

).

NO : Replace the ETACS-ECU.

TECHNICAL DESCRIPTION (COMMENT)

When one of the position light, side marker light or
license plate light does not illuminate, the harness,
connector(s), or bulb(s) may have a problem, or the
fuse may be burned out.

.

TROUBLESHOOTING HINTS

• Malfunction of bulbs

• Malfunction of rear combination light

• Malfunction of rear combination light harness

• Malfunction of license plate light

• Malfunction of headlight

• Malfunction of rear side maker light

• The wiring harness or connectors may have

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

DIAGNOSIS
