Understanding the Anti-Lock Braking System (ABS)
The ABS in the 2019 Sprinter 2500 is an advanced system that improves stability and control. It consists of several components working together to ensure efficient braking performance. Key parts include:
- ABS Control Module – The brain of the system that processes signals and regulates braking force.
- Wheel Speed Sensors – Detect the speed of each wheel to prevent lockup.
- Hydraulic Control Unit (HCU) – Modulates brake fluid pressure to optimize braking force.
- ABS Relays and Fuses – Protect the electrical circuits and ensure smooth operation.
- Brake Pedal Position Sensor – Monitors pedal movement and sends signals to the ABS module.
- CAN Bus Communication – Allows the ABS to interact with other vehicle control systems.

- CAN Low: Yellow
Common ABS Issues & Troubleshooting
If you’re experiencing issues with your Sprinter’s ABS, understanding the wiring diagram can help diagnose the problem. Here are some common issues and how to troubleshoot them:
1. ABS Warning Light On
- Check if the ABS fuse is blown and replace it if necessary.
- Inspect the wheel speed sensors for dirt, damage, or loose connections.
- Scan for ABS fault codes using a diagnostic tool.
2. Brakes Locking Up
- Verify that the ABS module is receiving power (Red wire: 12V supply).
- Inspect the hydraulic control unit wiring for corrosion or damage.
- Test the pressure sensor wires for proper signal transmission.
3. Loss of ABS Function
- Ensure the CAN Bus wires (Green and Yellow) are intact and properly connected.
- Check for faulty relays in the ABS control circuit.
- Perform a module reset using a scanner to clear any error codes.
