CAMPAIGN IDENTIFICATION NUMBER

Number 92E861 has been assigned to this campaign. This number will appear on all communications and documentation of any nature dealing with this campaign.

AFFECTED VEHICLES

^ 1986 I-Mark (JT) Federal non-turbocharged models equipped with automatic transmission.

^ 1986 I-Mark (JT) Federal non-turbocharged models equipped with manual transmission registered in high-altitude states *.

* High-altitude states are Colorado, Nevada, New Mexico and Utah.


SERVICE INFORMATION

Affected vehicles are out of compliance with Federal emission standards. As a result, they may fail state mandated emissions tests.

To correct this condition, the Programmable Road Only Memory (PROM computer chip) in the ECM must be replaced. On vehicles equipped with automatic transmission, a spark delay valve must also be replaced. Use only parts listed in "Parts Information" section of this Campaign Bulletin.

OWNER NOTIFICATION

Owners of affected vehicles have been notified by letter (copy enclosed) from American Isuzu Motors Inc. Each Isuzu dealer (except Calif.) will be supplied a copy of the AIMI Campaign Report (AWS 123-1A) listing affected vehicles assigned to that dealership. If none of the affected vehicles are assigned to your dealership, no report will be sent. The Report contains VIN and detailed owner information obtained from state motor vehicle registration records.

The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, dealers are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

FLAT RATE MANUAL UPDATE INFORMATION



1986 ISUZU I-MARK RECALL CAMPAIGN

Dear Isuzu I-Mark Owner:

The Environmental Protection Agency and Isuzu exhaust emission testing have determined that some 1986 I-Mark vehicles may exceed the Federal carbon monoxide emission standard.

WHAT IS THE RECALL FOR?

The amount of carbon monoxide emission will be reduced by a modification to the emission control system. A PROM (computer memory chip) will be replaced in the electronic control module (ECM). If your vehicle is equipped with automatic transmission, a spark delay valve will also be replaced.

WHAT SHOULD YOU DO?

Please make an appointment with your authorized Isuzu Dealer, who will make the emission system modification at no charge. The labor time necessary to perform this service correction is approximately one hour. Please ask your Isuzu Dealer if you wish to know how much additional time will be needed to schedule and process your vehicle. Please refer to Campaign Bulletin Number SB92-03-007 when you contact your Dealer.

To ensure your full protection under the emission warranty provisions, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could be determined as lack of proper maintenance of your vehicle. Also, your vehicle could fail a state or local emission inspection if this repair is not accomplished.

You may contact the appropriate Isuzu Regional Office listed in the back of your Owner's Manual, or the National Customer Relations Office, American Isuzu Motors Inc., P.O. Box 2280, City of Industry, CA 91746 (phone 800-255-6727), if the Dealer does not schedule a service date within a reasonable time.

If your Isuzu Dealer and the Customer Relations office are unable to remedy this condition within a reasonible time, you may wish to advise the Environmental Protection Agency at the following address: Director, Manufacturer's Operations Division (EN-340-F), United States Environmental Protection Agency, 401 M Street SW, Washington, DC 20460.

We are indeed sorry for any inconvenience and appreciate your cooperation in having this correction to your Isuzu vehicle completed.


IMPORTANT:
If you have sold your Isuzu vehicle, please enter the owner's name and address, if known, on the enclosed "Change of Information" postcard and drop it in the mail. Postage has already been paid. We will contact the new owner.
