ECM Reference Setting (ECM Relearn Procedure)
WARNING: This page is about a different car, the 1993 Volkswagen EuroVan. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The Electronic Control Module (ECM) must be reset if Blue engine coolant temperature sensor has been disconnected while the engine is running or if throttle body, throttle valve potentiometer, airflow sensor or ECM have been replaced. This procedure is not necessary on Digifant II systems.
