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.
