The Integrated Dynamic Brake (IDB) reports a high power supply voltage.
<0.01% (Extremely rare)
Power braking assist reduced
Braking may require increased effort
The IDB enters fallback mode and relinquishes controlling status to the Redundant Control Unit (RCU). The RCU may assume controlling status and perform backup brake boost, but Electronic Brake Distribution (EBD), Anti-lock Brake System (ABS), Brake Traction Control (BTC), Vehicle Dynamics Control (VDC), Panic Brake Assist (PBA), Hydraulic Fade Compensation (HFC), Controlled Deceleration via Parking brake (CDP), Brake Disc Wipe (BDW), External Brake Request (EBR), and Secondary Collision Mitigation (SCM) may be unavailable. Increased braking effort may be necessary to achieve desired deceleration. The vehicle should be driven with extreme caution.
The Integrated Dynamic Brake (IDB) reports a high power supply voltage.
Power supply voltage is greater than 19V for 500 milliseconds.
Power supply voltage is less than 18V for 500 milliseconds.
