INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (HEADLIGHT CLEANER OPERATION)

(a) Using the Techstream, perform the Active Test Scan Tool Testing and Procedures.

Main Body

HINT
The headlight cleaner system operates when the front wiper washer switch (windshield wiper switch) is turned on for the first time. After that, the headlight cleaner system cannot be operated with the front wiper washer switch (windshield wiper switch) until the engine switch is turned off and then turned on (IG).

OK:

Headlight cleaner operates.
