SECTION VIIC SERVICE PROGRAMMING SYSTEM
2005 Tech 2 User’s Guide VII - 46
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.
