Regenerative Braking System Malfunction

on 2023 Chevrolet Silverado 1500 6.2L V8 L87 · 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

  1. Check hybrid battery SOC and health
  2. Scan hybrid powertrain module for related codes
  3. Test motor-generator output during braking
  4. Verify CAN communication between brake and hybrid modules
  5. Check for high-voltage isolation faults

Repair notes

Diagnose hybrid powertrain system. Regenerative braking requires a healthy battery and motor-generator system.
