Off-Board Remote Programming

NOTE: The Off-Board Programming Adapter Kit (J-41207-C) is required when a PCM must be programmed without having the vehicle present. The adapter allows the module to be turned ON and communicate with the scan tool.

NOTE: Ensure the Tech 2(R) and the Techline(R) terminal are both equipped with the latest software before performing service programming.

Obtain the Vehicle Identification Number (VIN) of the vehicle for which the module is being programmed.
Launch the TIS application at the Techline(R) terminal.
Select the SERVICE PROGRAMMING SYSTEM.
Highlight the following information on the SELECT DIAGNOSTIC TOOL AND PROGRAMMING PROCESS screen:
- Select DIAGNOSTIC TOOL, then select TECH 2(R).
- Select PROGRAMMING PROCESS. Identify whether an existing module is being reprogrammed or a module is being replaced with a new one.
- Select ECU LOCATION. Select OFF-BOARD PROGRAMMING ADAPTER.
Select NEXT.

NOTE: Ensure the correct connector for the PCM is used.

Follow the directions on the PREPARING FOR COMMUNICATION screen for connecting the following components:
- The PCM.
- The Off-Board Programming Adapter (OBPA). Refer to the TIS users guide for a listing of the OBPA.
- The Tech 2(R).
Select the SERVICE PROGRAMMING REQUEST INFORMATION function on the Tech 2(R).
Follow the Tech 2(R) instructions to obtain the module data and security information.
After the Tech 2(R) has received the data from the PCM, exit the REQUEST INFO mode.
Disconnect the Tech 2(R) from the OBPA.
Turn OFF the Tech 2(R).
Connect the Tech 2(R) to the Techline(R) terminal.
Turn ON the Tech 2(R).
Select NEXT at the Techline(R) terminal after the Tech 2(R) start-up screen appears.
Enter the VIN of the vehicle that will be receiving the PCM.
Select NEXT.

NOTE: 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 the Techline(R) Customer Support.

Select the type of programming to be performed from the following categories:
- NORMAL - Used for updating an existing calibration or programming a new controller.
- VEHICLE CONFIGURATION INDEX (VCI) - Used for updating an existing controller or programming a new controller for newer vehicles whose VINs are not yet in the database.
- RECONFIGURE - Used to reconfigure a vehicle for changes in tire size and/or axle ratios.
Select NEXT.
Select a calibration on the CALIBRATION SELECTION screen, if necessary.
Ensure all the desired folder tabs have a Green check mark.
Select NEXT.
Verify the current and the selected calibration of the PCM on the SUMMARY screen.
Select NEXT.

NOTE: Select CANCEL if a message is received stating the calibration selected is already the current calibration in the PCM and reprogramming with the same download is not allowed.

Select OK.
On model year 1996 and newer controllers, a CRANKSHAFT POSITION (CKP) RELEARN procedure box may appear. Select OK.
Follow the on-screen instructions, if any, when the PROGRAM CONTROLLER/PROGRAMMING COMPLETE screen appears.
Select CLOSE.
Turn OFF the Tech 2(R).
Disconnect the Tech 2(R) from the Techline(R) terminal.
