DKR/DKE (Throttle Response/Throttle Increase)

ASC - EML INTERFACES BOSCH - 750iL/850





The Automatic Slip Control (ASC) control module uses the interfaces with the Electronic Throttle Regulation (EML) control module to request DK throttle regulation during an ASC control regulation. Two circuits are used, called DKR and DKE, to signal the EML of the requested throttle regulation.

^ DKR - is the throttle reduction signal line.
^ DKE - is the throttle increase signal line.

The DKR and DKE circuits are maintained by the ASC control module with a fixed frequency and have a specific duty cycle during normal vehicle operation. During an ASC control regulation, the duty cycle of the signal line will vary to indicate the amount of throttle opening request by the ASC control module.
