AI Customer ServiceRecently I''ve had intermittent failure of the ABS system in my V60 T6 R-Design. When it happens, the brakes act funky for a second (or the car will fail to take off), and the light
AI Customer ServiceProblems with the communication network can cause the ABS module to lose communication with other control modules. This can be due to network interruptions, software glitches, or compatibility issues between different modules in the vehicle.
When energized, the solenoid coils open the valves in the ABS valve body, allowing them to flow pressurized brake fluid to the wheels. The module ensures that the brakes are applied evenly and at the right pressure. When the module malfunctions, it can compromise vehicle safety, leading to potential issues during braking.
The only thing that hints to the problem is in the message center under the odometer it reads "ABS COMM FAIL". I have checked any relevant fuses and relays, the plugs and pins to the module are fine, the module itself is fine, the plugs and pins to the ECM are fine. I tried unplugging an abs sensor and the light on the dash doesn't come on.
1. Inspect the wiring and connectors in the ABS system for damage or corrosion. 2. Perform diagnostic tests on the ABS control module to identify any faults. 3. Ensure proper communication between the control modules by checking for any interference. 4. Use specialized diagnostic tools to pinpoint the specific cause of the communication failure. 5.
Faulty ABS Module: A malfunctioning ABS module can generate the U0121 trouble code as it hinders proper communication within the system. ABS Module Circuit Issues: Problems within the ABS module circuit can lead to U0121, disrupting the communication process.
The ABS module is the control center of this system. As you’ll see below, the module consists of a circuit board and solenoid driver coils. When energized, the solenoid coils open the valves in the ABS valve body, allowing them to flow pressurized brake fluid to the wheels.
