SERVICE INFORMATION
The following General Motors vehicles contain Electronically Reprogrammable Devices (i.e. PCM, VCM, ECM).

The Environmental Protection Agency (EPA) has requested that all new vehicle manufacturers ensure their dealers/retailers are aware that they are responsible for providing customers access to reprogramming services at a reasonable cost and in a timely manner.
Although programming of controllers has become a common service practice at GM dealers/retailers, the EPA has received reports from consumers and the aftermarket repair industry that they were unable to purchase a new (programmed) Electronically Reprogrammable Device (ERD) over-the-counter. As a result, on August 1, 1995, the Federal Government issued a regulation requiring all manufacturers to make available reprogramming to the independent aftermarket by December 1, 1997.
Today, the Off Board Programming Adapter (OBPA) is used to reprogram ERD's sold over-the-counter. For all practical purposes, the OBPA takes the place of the vehicle when the vehicle is not available.
Figs. Fig 1 thru Fig 3 is a list of dealerships/retailers who currently own the OBPA. These locations are equipped to provide over-the-counter preprogrammed ERD's. The hardware required to perform reprogramming in addition to the OBPA is a Techline terminal, Tech 1/1A and associated cables and adapters.
The current OBPA can support reprogramming on all late model General Motor's vehicles except:
- Premium V-8's
- 1996 Diesel Truck
- Cadillac Catera
- All 1997 programmable vehicles (requires use of the Tech 2)
A modification to the OBPA is being offered by Kent-Moore to support these additional vehicles to allow reprogramming using the Tech 2. The revisions to the OBPA for the Tech 2 is very important as the Tech 2 is the only tool used for service programming for 1997 and future vehicles to have the modifications performed, contact Kent-Moore at (800) 345-2233. The revisions (part number J 41207 REV-C) are free of charge for GM dealerships/retailers.
A dealership/retailer can purchase the OBPA by contacting Kent-Moore (part number J 41207-C). Support on how to use the OBPA is provided by the Techline Customer Support Center (TCSC) at (800) 828-6860 (English) or (800) 503-3222 (French).
If you need to purchase an OBPA and/or cable, contact Kent-Moore at (800) 345-2233. The OBPA retails for $695.00 (includes all revisions 1-4) under part number J 41207-C.
