DRIVER DOOR SWITCH SHORT CIRCUIT
AFFECTED VEHICLES


2006-2007MY Isuzu Ascender Vehicles

This service procedure has been revised. The procedure for applying the protective
coating on the door module has been removed. Please discard previous bulletin SB1304-S001.
SERVICE INFORMATION

CONDITION
The manufacturer of your vehicle, General Motors, has decided that a defect, which relates to
motor vehicle safety, exists in certain 2006-2007 Isuzu Ascender vehicles originally sold or
currently registered in: Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa,
Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New
Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin.
If fluid enters the driver’s door module, it may cause corrosion that could result in a short in
the circuit board. A short may cause the power door lock and power window switches to
function intermittently or become inoperative. In rare cases, a short may cause overheating,
which could melt components of the door module, producing odor, smoke, or a fire.
CORRECTION
Service Facilities are to inspect the part number of the door module and, if necessary, install
a new door module.
VEHICLES INVOLVED
Involved are certain 2006-2007 model year Isuzu Ascender vehicles.
Important: Service Facilities are to confirm vehicle eligibility prior to beginning repairs by
using the Isuzu Communication System (ICS).
For Service Facilities with involved vehicles, a listing of involved vehicles containing the
complete vehicle identification number has been or will be provided. Service Facilities will not
have a report available if they have no involved vehicles currently assigned.

OWNER NOTIFICATION
Isuzu will notify customers of the revised service procedure involved in this recall in the near
future.
SERVICE FACILITY RECALL RESPONSIBILITY
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used
item of motor vehicle equipment (including a tire) covered by this notification under a sale or
lease until the defect or noncompliance is remedied.
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is
subject to a recall of this type must be adequately repaired within a reasonable time after the
customer has tendered it for repair. A failure to repair within sixty days after tender of a
vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is
not adequately repaired within a reasonable time, the customer may be entitled to an
identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price
less a reasonable allowance for depreciation. To avoid having to provide these burdensome
remedies, every effort must be made to promptly schedule an appointment with each
customer and to repair their vehicle as soon as possible. In the recall notification letters,
customers are told how to contact the US National Highway Traffic Safety Administration if
the recall is not completed within a reasonable time.
Service Facilities are to service all vehicles subject to this recall at no charge to customers,
regardless of mileage, age of vehicle, or ownership, from this time forward.
In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in
your for service in the future, you must take the steps necessary to be sure the recall
correction has been made before selling or releasing the vehicle.
