Basic conditions for adaptation of the throttle unit:
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
- ignition on / engine off
- battery voltage above 10 V
- accelerator pedal (AP) released (unaffected)
- the car must be stationary (no speed signal)
- engine coolant temperature (ECT) between 5 and 100 °C
- intake air temperature (IAT) above 5 °C.
During adaptation, the engine control module (ECM) checks that the values obtained are within reasonable limits. This helps to determine whether the throttle unit is functioning correctly or not. When the adaptation has been carried out, all relevant values are stored in the EEPROM memory in the control module so that they can be retrieved if the power supply is broken. This means that if the battery is replaced for example, a new adaptation is not necessary.
