ASR

Anti-Slip Regulation (ASR)
The ASR option is only available on Front Wheel Drive (FWD) vehicles. Observe control module coding for these vehicles. The function of ASR requires an exchange of signals between the ABS control module -J104-, the Engine Control Module (ECM) and the Transmission Control Module (TCM). The control modules communicate with each other.

There are two communication systems at work:
- Data is transferred via several single wires.
- Data is transferred via the CAN-bus. The CAN-bus only contains two lines. These transfer all required data.

To determine which communication system is transferring data, use the "Check control module version" function and check the table "Control module versions".

ASR prevents the wheels being powered from spinning during acceleration by reducing engine load. It is active throughout the entire speed range. The EDL and ASR functions work in combination during vehicle acceleration.

ASR can be switched on and off by pressing the traction control button in the center of the center console. ASR is re-activated on its own when the ignition is switched on. When the traction control button is operated, the ASR indicator lamp lights up in the instrument cluster. During adjustment mode, the indicator lamp blinks three times per second.
