Computerized Engine Controls: ECM: Notes

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1998 Volvo V90, 1998 Volvo V70, 1998 Volvo S90, 1998 Volvo S70, and 1997 Volvo V90. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: The ECM must not be removed from the car until the main relay has interrupted its power supply. This may take up to 150 seconds on Motronic 4.4 systems after the ignition has been switched off. Cars with an immobilizer can take up to 245 seconds after the ignition has been switched off.
