Instrument Panel Integration Module (IPM) Replacement
If the Instrument panel integration module (IPM) is replaced, an automatic Re-Calibration of all the actuators will occur. For the best Re-calibration results, start and run the engine for at least one minute after installing the new module. Do not adjust any controls on the HVAC control module during the Re-Calibration procedure. If interrupted, improper HVAC performance may result. No additional procedures are necessary.
