Introduction

Some 2012 model year Camry and Camry HV vehicles may exhibit a condition where the passenger headlight and rear defogger operate continuously.

This condition may be caused by a poor ground for the Engine Room Junction Block Assembly on the left fender side panel bracket after a collision repair. This may occur during body shop repairs orother repairs where the left side fender bracket grounds were left loose, not properly attached using correct bolts, or improperly painted, and the vehicle's battery was connected.

NOTICE
BEFORE performing work on electronic components, components including grounds, or fenderbrackets with grounds, disconnect the cable from the negative (-) battery terminal to preventdamage to the electrical system or components.
