Campaign - Multiplex Control Unit Replacement: Overview

01-035

March 13, 2001

Applies To:
2001 Accord V6 LX 4-door - From VIN 1HGCG1...1A000001 thru 1HGCG1...1A039930

Product Update: Accord Driver's Multiplex Control Unit

BACKGROUND

The delay interval will not adjust with the INT TIME ring when the windshield wipers are operating in intermittent mode. The interval is fixed at about 4 seconds. This is controlled by the multiplex control system.

There are three multiplex control units in the vehicle, made by two manufacturers. For the multiplex control system to operate properly, all three units must be made by the same manufacturer. In the affected vehicles, the passenger's multiplex control unit and the door multiplex control unit are made by the same manufacturer, but the driver's multiplex control unit is made by a different manufacturer. This causes the problem with the windshield wiper delay interval.
