Performing Off-Board Programming Adapter (OBPA) Pass-Thru SPS
The OBPA is used in situations where a module must be programmed without having the vehicle present.
This need may arise, for example, when a dealership parts department sells a control module to a retail or
aftermarket customer. To perform SPS in this scenario requires an off-board programming adapter. The
adapter allows the module to be powered up and communicate with the scan tool. The part number for the
OBPA kit is J-41207-C. It is available for purchase by calling 1-800-GM-TOOLS (1-800-468-6657), or send
your order by fax at 1-800-578-7375.
NOTICE
• Prior to performing SPS, make sure that the scan tool and the terminal are both equipped with the
latest software.
• To help avoid possible controller failure, make sure all cable connections are secure.
