ELECTRONIC CONTROL MODULE EXCHANGE PROGRAM

A two-part ECM Return Tag will soon be included in the remanufactured ECM container. All areas of the tag are to be completed for all ECM's returned for repair. After completion of the tag, the extra copy is to be attached to the scrap copy of the repair order and retained for disposition by the Pontiac Zone Representative.

The following instructions indicate the information required in all areas of the tag on all ECM's returned for repair. The example below indicates a properly completed tag.

1. Dealership name.

2. Dealership five (5) digit code number assigned by the car division. This should be the same code number that is used on the warranty claim.

3. Repair order number if repair is completed in the dealership or insert the letters OTC if the ECM was sold over the counter.

4. Complete vehicle serial number.

5. Original vehicle delivery date on warranty claims. Out of warranty repairs can be listed UNKNOWN.

6. Vehicle mileage listed on the repair order or current mileage if no repair order is written.

7. Repair order date or the date of the counter slip on over the counter sales.

8. Service part number listed on the ECM removed from the car.

9. All diagnostic codes obtained during the diagnostic circuit check.

10. Customer complaint when the car was brought in for service.

11. Malfunction found and the chart used to complete the repair.

Proper completion of the return tag will prevent any undue delay in the dealership receiving parts return credit. It will also reduce the possibility of an unrepaired ECM being installed in a customer's car.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
