on 2006 Ford Explorer 4.6L V8 · 4WD
What this code means
General fault in the regenerative braking system that recovers energy during deceleration.
Symptoms
- Regenerative braking warning light
- Reduced fuel economy
- Braking feel changes
- Battery not charging during braking
Common causes
- Hybrid battery state-of-charge issue
- Inverter malfunction
- Motor-generator fault
- Communication error between brake and hybrid modules
Diagnostic steps
- Check hybrid battery SOC and health
- Scan hybrid powertrain module for related codes
- Test motor-generator output during braking
- Verify CAN communication between brake and hybrid modules
- Check for high-voltage isolation faults
Repair notes
Diagnose hybrid powertrain system. Regenerative braking requires a healthy battery and motor-generator system.
