DAF 1778554 1361393 ABS SENSOR – Precision Safety and Stability for Heavy-Duty Vehicles
The Anti-lock Braking System (ABS) is one of the most critical safety components in modern trucks and commercial vehicles. Among the essential parts of this system are ABS sensors, which continuously monitor wheel speed and send data to the electronic control unit (ECU) to prevent wheel lock-up during braking. The DAF ABS sensors with part numbers 1778554 and 1361393 are genuine OEM components used in various DAF trucks, designed for durability, accuracy, and seamless integration with the braking system.
These sensors not only enhance vehicle safety but also contribute to improved control, reduced stopping distance, and extended brake component life. This article explores the functions, specifications, installation guidelines, and benefits of the DAF 1778554 and 1361393 ABS sensors.
What Is an ABS Sensor?
1778554 1361393 ABS SENSOR, also referred to as a wheel speed sensor, is an electronic device that measures the rotational speed of each wheel. The sensor transmits real-time data to the ECU, which adjusts the braking force applied to each wheel to prevent skidding and maintain steering control during emergency or sudden braking situations.
In heavy-duty trucks like those manufactured by DAF, ABS sensors play a vital role in maintaining traction and vehicle stability, particularly under variable load conditions or on slippery roads.
Overview of DAF ABS Sensor Part Numbers 1778554 and 1361393
1778554 1361393 ABS SENSOR are part numbers assigned to high-performance wheel speed sensors used in DAF vehicles. While functionally similar, they may vary slightly in cable length, connector type, or mounting design depending on the axle configuration or model series.
These sensors are commonly installed on:
- DAF XF Series
- DAF CF Series
- DAF LF Series
They are compatible with WABCO and Knorr-Bremse ABS/EBS systems used across European truck platforms.
Technical Specifications
- Sensor Type: Inductive / passive wheel speed sensor
- Mounting Position: Front or rear axle hubs (depends on vehicle configuration)
- Connector Type: 2-pin or 3-pin plug (application-specific)
- Cable Length: Varies (typically between 600mm and 2200mm)
- Material: Stainless steel sensor tip, high-durability rubber insulation
- Operating Temperature: -40°C to +150°C
- Output Signal: Sine wave (voltage generated by magnetic field disruption)
- Resistance: Generally 1000 – 1600 ohms (check exact specification by vehicle model)
Functionality and Operation
DAF ABS sensors operate based on magnetic induction. As a toothed ring (also called tone ring or impulse ring) on the wheel hub rotates, it interrupts the magnetic field generated at the sensor tip. These interruptions produce an alternating voltage signal that increases with wheel speed. The ECU interprets this data and modulates brake pressure during braking events.
ABS sensors work in conjunction with other systems such as:
- Electronic Braking System (EBS)
- Electronic Stability Program (ESP)
- Traction Control System (TCS)
In modern vehicles, a malfunctioning ABS sensor not only affects braking safety but can also disable these interconnected systems.
Benefits of Using Genuine DAF ABS Sensors
1. Enhanced Braking Control
Genuine DAF sensors ensure accurate and consistent wheel speed data, which improves vehicle response during emergency braking, especially under load.
2. OEM Fit and Quality
1778554 1361393 ABS SENSOR are engineered to meet DAF factory specifications, ensuring correct fitment, long service life, and resistance to harsh conditions like water, mud, and road salt.
3. Prevention of ABS System Faults
Low-quality or incompatible sensors may cause intermittent ABS warning lights or system failure. Using genuine parts ensures system stability and diagnostic accuracy.
4. Reduced Maintenance and Downtime
High-reliability sensors reduce the risk of ABS errors that require workshop visits. Proper functioning sensors also reduce brake wear by optimizing system performance.
Common Symptoms of a Faulty ABS Sensor
- ABS warning light on the dashboard
- Traction control or stability system errors
- Pulsating brake pedal during normal braking
- Unresponsive ABS during sudden stops
- Unusual braking behavior on slippery surfaces
When these signs are observed, it is critical to diagnose the specific wheel and replace the faulty sensor to restore safe braking.
Installation and Maintenance
Installing DAF ABS sensors should follow manufacturer guidelines:
- Clean the mounting surface before installation
- Use proper torque values for bolts and connectors
- Avoid bending the sensor cable or exposing it to pinching hazards
- Check for proper clearance between sensor and tone ring
- Reset diagnostic codes after installation if required
Using dielectric grease on the connectors can help prevent moisture intrusion and electrical corrosion.
Applications and Compatibility
DAF 1778554 and 1361393 sensors are used across multiple vehicle generations, including:
- DAF XF105 / XF Euro 6
- DAF CF75 / CF85 / CF Euro 6
- DAF LF45 / LF55
These part numbers may also cross-reference with WABCO or other OEMs. Always verify using the truck’s chassis number or consult a DAF dealer.
