SUBJECT
E65, New DME Feature
SITUATION
A customer may complain about the following situation:
- Vehicle hesitates during acceleration
- Vehicle hesitates during constant driving
- Vehicle acceleration limited after a stop
No faults are stored in the DME.
CAUSE
With the launch of the E65, a new feature was implemented in the DME software to avoid unintentional acceleration during a panic stop due to misapplication of the accelerator pedal.
The DME will limit the acceleration demand signal, as soon as it detects a simultaneous brake and accelerator pedal input at a road speed greater than 20 km/h (approx. 12 mph).
The customer can unintentionally activate this feature by resting his left foot on the brake pedal during acceleration.
PROCEDURE
Please explain this important safety feature to the customer.
