Controller Specific Instructions
If “Crankshaft Position Variation Relearn Procedure” appears under “Controller Specific

Power on the Tech2. At the Tech2 title screen, press [ENTER].
3.3
Turn the vehicle ignition to the “on” position (engine off).
3.4
At the Tech2 Main Menu, select Service Programming System.

Select "F1: Program ECU" on the Tech2. The Tech2 will display the new
programming data
— VIN and software numbers. Verify, then select the soft key
Continue. The Tech2 will display the "Programming in Progress - Downloading
calibration file" screen.
3.6
When the transfer is complete, the Tech2

Was Successful.” Press the Continue soft key to exit the program. Turn the vehicle
ignition off first, then turn the Tech2 off and disconnect it from the vehicle.
Be sure to verify successful reprogramming.
Verifying Reprogramming
After any kind of control module programming, verify that programming was successful:
Turn the ignition off, wait at least 30 seconds, then start the vehicle to confirm that
reprogramming was successful. If the vehicle does not start or starts but runs rough,
repeat the SPS procedure.
Important
: Some vehicles will require that Idle Learn, TP Learn, Theft Deterrent Relearn,
or Crankshaft Variation Learn procedures be performed after programming. Consult the
appropriate service information for these procedures.
