SERVICE PROGRAMMING SYSTEM
NOTICE
Prior to performing SPS, it is important to heed the following precautions:
• Using an outdated version could damage vehicle modules. The Tech 2 and the terminal must have the latest software.
• Make sure the vehicle battery is fully charged. Battery voltage for SPS should be between 12 and 14 volts. However, a
battery charger must not be connected to the vehicle when using the Tech 2.
• Make sure the cable connections are secure. A disconnected cable could cause controller failure.
• If you use a laptop computer for pass-thru programming, ensure that the power supply is properly connected.
If powered by AC and the power cord becomes disconnected, it could interrupt programming and cause damage to
the control module. If the laptop is operating from its internal power source (batteries), then make sure it is adequately
charged to complete the SPS process.
Remote SPS Programming
The Remote SPS method is a three-step process that involves:
1. Connecting the scan tool to the vehicle and obtaining information from the module.
2. Connecting the scan tool to the PC and downloading a new calibration file from the PC to the scan
tool’s memory.
3. Reconnecting the scan tool to the vehicle and uploading the new calibration file to the module.
IMPORTANT: TIS supports Service Programming with the Tech 2 scan tool only.
Off-Board Programming
Off-Board Programming is used when a reprogrammable control module must be programmed away from
the vehicle. This method requires the use of an Off-Board Programming Adapter (OBPA), J-41207-C.
