Verifying Reprogramming

NOTE: Vehicles will require that Crankshaft Variation Learn or Theft Deterrent Relearn procedures be performed after programming. See CKP SYSTEM VARIATION LEARN PROCEDURE  and PROGRAMMING THEFT DETERRENT SYSTEM COMPONENTS  .

Verify the PCM programming was successful using the following procedure:

  1. Turn ignition switch to OFF position for 30 seconds.
  2. Start the engine.
  3. If the vehicle does not start or starts but runs rough, repeat the SPS procedure.
