Regenerative Braking System Performance Reduced

on 2012 Toyota Highlander 3.3L V6 Hybrid · AWD

What this code means

The regenerative braking system is not recovering the expected amount of energy during deceleration. The system may be partially or fully disabled.

Symptoms

  • Reduced regenerative braking force
  • Conventional brakes used more than normal
  • Brake pedal feel changed
  • Battery not charging during deceleration
  • Lower fuel economy (hybrid)
  • Reduced range (EV)

Common causes

  • HV battery fully charged or too cold
  • Motor/generator fault limiting regen
  • Battery management limiting charge rate
  • Friction brake system compensating
  • Traction control intervening during regen

Diagnostic steps

  1. Check battery SOC and temperature
  2. Monitor regen torque during deceleration
  3. Check for other hybrid system DTCs
  4. Inspect brake system for related codes
  5. Review BMS charge acceptance limits

Repair notes

Diagnose root cause - battery temperature, SOC limits, or motor fault. Regen may be intentionally limited by BMS to protect battery.
