STEP 5. Check the connector between daytime running
light-ECU connector A-96 and ignition switch for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

NOTE: After checking junction block connector D-01 and D-08,
check the wires. If junction block connector D-01 and D-08 are
damaged, repair or replace them. Refer to GROUP 00E, Har-
ness Connector Inspection

P.00E-2

.

Q: Are the connectors and terminals in good condition?

YES : Go to Step 6.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 6. Check the harness wire between daytime running
light-ECU connector A-96 (terminal No.2) and ignition

switch.

STEP 8. Check the daytime running light-ECU lighting
switch input circuit at daytime running light-ECU A-96.

(1) Disconnect the daytime running light-ECU.
(2) Turn the lighting switch "HEAD" position or passing switch

"ON".

(3) Measure the voltage between terminal 5 and ground.
Q: Is battery positive voltage (approximately 12 volts)

present?
YES : Go to Step 9.
NO : Go to Step 10.

STEP 9. Check the connector between daytime running
light-ECU connector A-96 and headlight relay connector
A-52X for loose, corroded or damaged terminals, or
terminals pushed back in the connector.

Q: Is connector between daytime running light-ECU

connector A-96 and headlight relay connector A-52X in
good condition?
YES : Go to Step 10.
NO : Repair or replace the damaged components. Refer to

STEP 10. Check the harness wire between daytime running
light-ECU connector A-96 (terminal No.5) and headlight
relay connector A-52X

Q: Is harness wire between daytime running light-ECU

connector A-96 (terminal No.5) and headlight relay
connector A-52X in good condition?
YES : Go to Step 11.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 11. Check the daytime running light relay (lower) and
(upper).

(1) Disconnect the daytime running light relay (lower) and

(upper).

(2) Follow the table below to check for continuity of the daytime

running light relay.

Q: Is the daytime running light relay continuity in good

condition?
