Common Faults:

• Low voltage detected at Terminal 30 (undervoltage)
• Low voltage detected at Terminal 15 (undervoltage)
• Communication problems with CAN 3 (EBS module not visible)
• Fault within the trailer CAN system
• Issue detected with rear axle steering

CAN Faults:

CAN 3, CAN 6a, CAN 6B, CAN 6D, CAN 11

We specialise in restoring these modules to full working condition, often within 2–3 working days. This service includes handling faults and common failure symptoms related to Mercedes MP4 EBS3-EBS4 Control Units.

Is your Mercedes MP4 showing brake-related faults or electrical warnings? If so, the EBS3 or EBS4 control unit may be the cause. These units often develop specific issues that affect performance. For example, you may see low voltage at Terminal 30 or Terminal 15. These undervoltage faults can lead to system errors and reduced braking efficiency. In addition, a CAN 3 communication problem can make the EBS module invisible to the rest of the system.

Moreover, some vehicles experience a fault within the trailer CAN system, which may result in unstable braking behaviour when towing. You could also notice an issue with the rear axle steering, which may affect handling. Although these problems are serious, they can often be repaired quickly and affordably.
