Reconfigure-Used to reconfigure a vehicle for changes in tire size and axle ratios.
IMPORTANT: When selecting the vehicle configuration index (VCI) programming type, a valid VCI number for the vehicle must be entered. This
number may be obtained from Techline Customer Support.
14. Select Next.
15. Select a calibration selection on the Calibration Selection screen, if necessary.
16. Ensure all the desired calibration folder tabs have a green check mark.
17. Select Next.
18. Verify the current and selected calibration of the control module on the Summary screen.
19. Select Next.
20. Select OK.
IMPORTANT: Select Cancel if you receive a message stating that the calibration selected is already the current calibration in the control module
and reprogramming with the same download is not allowed.
21. Select OK.
IMPORTANT: On model year 1996 and newer controllers, a crankshaft position (CKP) relearn procedure box may appear.

Description and Operation
SERVICE PROGRAMMING SYSTEM (SPS) DESCRIPTION
The service programming system (SPS) allows a technician to program a control module through the data link connector (DLC). The information
transfer circuit that is used at the DLC is the same serial data circuit used by the scan tool for retrieving diagnostic trouble codes (DTCs), displaying
data, clearing DTCs, etc. This procedure offers the ability to install software/calibrations matched to a particular vehicle.
Most control modules have 2 types of memory. The software/calibrations reside in the flash memory. The 2 types of memory are listed below:
-
Electrically Erasable Programmable Read Only Memory (EEPROM)
This type of memory allows selected portions of memory to be programmed while other portions remain unchanged.
Certain learned values reside in the EEPROM, such as:
-
The vehicle identification number (VIN)
-
The crankshaft variation learned position
-
The software/calibrations identification numbers
-
The control module security information
-
Flash Read Only Memory
Flash Memory Flash memory has increased memory storage capacity. During programming, all information within this type of memory is erased,
and then replaced with entirely new information.
Service Programming Methods
The 4 methods of programming a control module and the proper tools for each method are as follows:
-
Remote Programming:
-
The Tech 2 or other scan tool, Techline Terminal or a personal computer equipped with General Motors Corporation authorized programming
software-The Tech 2 or other scan tool is used as an interface between the vehicle and the Techline Terminal or a personal computer.
-
The control module is installed in the vehicle
-
Pass Thru Programming:
-
The Tech 2 or other scan tool, Techline Terminal or a personal computer equipped with General Motors Corporation authorized programming
software-The Tech 2 or other scan tool is used as an interface between the vehicle and the Techline Terminal or a personal computer.
-
The control module is installed in the vehicle.
-
Off-Board Remote Programming, Vehicle NOT Available:
-
The Tech 2 or other scan tool, off-board programming adapter (OBPA), Techline Terminal or a personal computer equipped with General
Motors Corporation authorized programming software-The Tech 2 or other scan tool is used as an interface between the vehicle and the
Techline Terminal or a personal computer.
