Common Symptoms
- ABS and brake warning lights both on
- Rear brakes locking prematurely
- Uneven braking front to rear
- Vehicle nose-diving during braking
- EBD warning message on dash
Probable Causes (Ranked by Likelihood)
- Rear wheel speed sensor failure affecting EBD calculation Very High
- ABS hydraulic module valve fault High
- Rear brake pressure sensor error Moderate
- ABS control module EBD algorithm fault Low
Step-by-Step Diagnostic Procedure
-
Scan ABS module for EBD-specific DTCs
-
Check rear wheel speed sensor readings
-
Test rear brake pressure during controlled stops
-
Inspect rear brake components for uneven wear
-
Monitor ABS module live data during braking
Frequently Asked Questions
What is electronic brake force distribution?
EBD uses the ABS system to automatically adjust the braking force between front and rear wheels based on vehicle load and weight distribution, ensuring optimal braking performance.
Why are both ABS and brake lights on?
When the EBD system fails, it is considered a critical safety issue because it affects basic brake balance. The system illuminates both lights to indicate a more severe problem than ABS alone.
Is EBD more important than ABS?
EBD operates during all braking events to maintain proper brake balance, while ABS only activates during wheel lockup situations. EBD failure is considered more critical because it affects every stop.
