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
