What causes the cruise control system failure in BMW 3 Series?
1 Answers
The cruise control system (CRUISE CONTROL SYSTEM), abbreviated as CCS, is also known as speed control device or autonomous driving system. Reasons for cruise control system failure include: Internal control unit or circuit failure: For instance, the ACC control unit needs to transmit signals to both ICM and LDM units. If these units themselves have issues or there are connection faults between them, signals cannot be properly transmitted. Wheel speed sensor: If you receive "cruise control system failure" warnings along with alerts related to DSC, ABS, or RPA systems, it's highly likely caused by malfunctioning wheel speed sensors.
