In a 3-channel ABS system, which wheels are on the same circuit?

In a 3-channel ABS (Anti-lock Braking System), the configuration typically involves two channels for the front wheels and one channel for the rear wheels. This means that both rear wheels are on the same circuit, operating together under a single control unit. The two front wheels each receive individual control, allowing the system to manage braking more effectively according to the different performance and grip levels observed at each wheel. This type of system is designed to assist in preventing wheel lock-up during braking, helping maintain vehicle control.

The option identifying both rear wheels on the same circuit accurately reflects how the 3-channel ABS is structured, optimizing braking performance while ensuring safety. Understanding this configuration is crucial for diagnosing and servicing ABS systems properly.
