Verifying Reprogramming

WARNING: This page is about a different car, the 2003 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

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.

Verify the control module programming was successful using the following procedure:

Turn OFF the ignition for 30 seconds.

IMPORTANT: Repeat the SPS procedure if the vehicle does not start or starts but runs rough.

Start the engine.
