STEP 39. Check the ground circuit to the license plate 
light. Test at license plate light assembly connector I-04. 
(1) Disconnect license plate light assembly connector I-04 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 : Go to Step 42.
NO :  Go to Step 40.

STEP 40. Check license plate light assembly connector I-
04 for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is license plate light assembly connector I-04 in good 

condition?
YES : Go to Step 41.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the license plate lights illuminate 

normally.

STEP 41. Check the wiring harness between license plate 
light assembly connector I-04 (terminal 1) and ground.
Q: Is the wiring harness between license plate light 

assembly connector I-04 (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 license plate lights illuminate normally.

damaged terminals, or terminals pushed back in the 
connector.
Q: Are license plate light assembly connector I-04 and 

front-ECU connector A-07X in good condition?
YES : Go to Step 43.
