060604 - The unit A10B has detected under voltage or short circuit to ground
18F0FF - Function limitation esp
220303 - Short circuit to positive, Abs solenoids left / right front axle
730201 - The power supply of the unit A10B is too low
75020C - Internal fault

The Mercedes brake control unit with code OE A0014460936 è l’unità electronic management system EBS (Electronic Braking System) developed by Wabco/ZF for Mercedes Euro VI commercial vehicles. È installed on trucks and buses of the German manufacturer and integrates advanced functions such as ABS, electronic assisted braking and stability controlà ESP.

This ECU è designed exclusively for Mercedes, with a’robust architecture and dedicated components. The’unità controls and monitors two pneumatic circuits It is an electronic circuit, processing signals from sensors and onboard devices.

DIPA canò intervene to review these modules thanks to its experience and expertise.

Operation and managed signals

Input signals

• Position and pressure of the brake pedal
• Speedà of the wheels via 4 or 6 ABS sensors
• Actual pressure in the braking circuits, thanks to internal sensors
• Status of connected devices, such as trailer retarder and ABS

Output controls

• Modulating solenoid valves for front and rear circuits
• Trailer EBS valve
• Warning lights and data communication to instrumentation

L’unità supports firmware updates and in-depth diagnostics both through official Mercedes tools and through Wabco/ZF interfaces.

Typical faults

No communication/diagnosis with the ESP control unit possible.
Loss of functionalityà complete, intermittent, or permanent.
Detected incorrect battery voltage value.

Error Codes
060601 - The unità A10B has detected under voltage or short circuit to ground
060604 - The unità A10B has detected under voltage or short circuit to ground
18F0FF - ESP function limitation
220303 - Short circuit to positive, ABS solenoids left/right front axle
730201 - The power supply of the unità A10B è too low
75020C - Internal fault

DIPA recommends:

• Check power supply on battery pin and ignition switch
• Check status of the multipole connector, presence of oxidation
• Measure resistance and continuityà of the CAN line
• Test ABS sensors and brake pedal sensor

Conclusions

DIPA offers a wide range of spare parts: from original ones to aftermarket ones selected from the best manufacturers on the market. Not only that: it also has refurbished components with performance equal to new, which allows for savings in replacement and contributes to the protection of the’environment thanks to the’circular economy. If the replacement that suits you is not è available, don't worry: DIPA canò revise “on demand” your part, restoring its full functionalityà and safety in a short time.
