Remote Programming
NOTE:
The Technical Information System (TIS) supports service programming with the Tech 2 scan tool only.
The Remote Serviced Programming System method is a 3 step process that involves the following procedures:
- Connecting the Tech 2 to the vehicle and obtaining the information from the module.
- Connecting the Tech 2 to the terminal and downloading a new calibration file from the terminal into the Tech 2 memory.
- Reconnecting the Tech 2 to the vehicle and uploading the new calibration file into the module.
Performing the Remote Procedure
- Connect the Tech 2 to the vehicle and obtain the module information using the following procedure:
- Connect the Tech 2 to the vehicle Data Link Connector (DLC), with the engine and the Tech 2 off.
- Turn on the Tech 2.
- Press ENTER at the title screen.
- Turn on the ignition, with the engine off.
- Select SERVICE PROGRAMMING SYSTEM at the main menu.
- Select REQUEST INFO. Select REQUEST INFO again if a vehicle identification number (VIN) was previously stored in the Tech 2.
- Enter the vehicle description by following the on-screen instructions.
- Turn off all accessories and select CONTINUE.
- Verify that the correct VIN is entered on the Tech 2 and select YES. Select NO and write down the VIN if the VIN is incorrect.
- Turn off the Tech 2.
- Disconnect the Tech 2 from the vehicle.
- Turn ignition off.
- Transfer the data from the terminal to the Tech 2 using the following procedure:
- Connect the Tech 2 to the terminal.
- Launch the TIS application at the terminal.
- Select the SERVICE PROGRAMMING SYSTEM at the main screen.
- Highlight the following information on the SELECT DIAGNOSTIC TOOL and PROGRAMMING PROCESS screen:
- SELECT DIAGNOSTIC TOOL - Select Tech 2.
- 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 VEHICLE.
- Select NEXT.
- Verify the connections and select NEXT.
- Verify the VIN and select NEXT. You may receive a message stating that the control module could be a service control module if you selected NO to the VIN being correct. Click OK.
- Select the appropriate controller for the vehicle being serviced.
- 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 axle ratios.
- Select NEXT.
- Select the appropriate calibration file for the vehicle being serviced. Refer to Service bulletins before service programming is performed if the bulletins are listed along with the calibration files.
- Select NEXT.
- Verify your selection on the Summary screen. 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.
- 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 Customer Support. - Perform the CRANKSHAFT POSITION VARIATION RELEARN procedure using the Special Functions feature, if applicable. See CRANKSHAFT POSITION SYSTEM VARIATION LEARN PROCEDURE .
- Close the application and return to the TIS application selection screen after the download is complete.
- Turn off the Tech 2.
- Disconnect the Tech 2 from the terminal.
- Transfer the data from the Tech 2 to the control module using the following procedure:
- Connect the Tech 2 to the vehicle DLC, with the engine and the Tech 2 off.
- Turn on the Tech 2.
- Press ENTER at the title screen.
- Turn ignition on, with engine off.
- Select SERVICE PROGRAMMING SYSTEM.
- Select the PROGRAM ECU function on the Tech 2.

Verifying Reprogramming
- Turn off the ignition for 30 seconds.
- Start the engine. Repeat the SPS procedure if the vehicle does not start or starts but runs rough.
- Some vehicles may require the following service procedures to be performed after programming:
- The Crankshaft Position Variation Learn procedure.
- The Engine Oil Life reset procedure.
- The Idle Learn procedure.
- The Inspection/Maintenance complete system set procedure.
- The Vehicle Theft Deterrent Password Learn procedure.
- The Throttle Position (TP) sensor learn procedure.
