Sensor Wheel Adaptation
Necessary after:
- Re-programming DME control unit
- Replacing DME control unit
Necessary before:
- Misfire diagnostics
How?
- Drive with engine overrun:
- 1.1. Meet preconditions:
- 1.1.1. Engine at operating temperature.
- 1.2. Accelerate to 3, 000 RPM (U/Min
) three times in quick succession in 2nd gear and allow vehicle to roll with gear engaged (engine overrun).
Information
- Adaptation values are deleted or stored in EEPROM when ignition is switched off after control unit run-on has ended.
This depends on the run-on period of the engine compartment purge fan.
The run-on period of the engine compartment purge fan AFTER ignition is switched off depends on the engine compartment temperature.
The run-on period is as follows at the following engine compartment temperatures:
- < 45 °C: approx. 50 seconds
- 45... 70 °C: approx. 200 seconds
- > 70 °C: up to 20 minutes
- 1.3. Switch off ignition.
- 1.1. Meet preconditions:
