POWER WINDOW / ROOF INITIALIZATION PROCEDURES

TECHNICAL SERVICE BULLETIN

Introduction

This bulletin clarifies the initialization procedures that are necessary if power is lost to the driver's door, moon roof, or back door ECU. It is necessary to re-initialize one or more of these systems if the main power source is lost either by a battery being disconnected, fuse being removed, or ECU disconnected from power. This TSB will aid in recognizing the available systems for faster and more accurate service.
