The Integrated Dynamic Brake (IDB) pump motor is stuck.
<0.01% (Extremely rare)
Power braking assist reduced
Braking may require increased effort
Only Electronic Brake Distribution (EBD) may be available. 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 Anti-lock Brake System (ABS), Brake Traction Control (BTC), Vehicle Dynamics Control (VDC), Panic Brake Assist (PBA), Hydraulic Fade Compenration (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) pump motor is stuck.
The measured motor rotor position is not changing in response to applied currents, or measured brake pressure does not follow the target pressure.
The motor position origin and pump piston housing walls are set normally at the start of the next power cycle. If the condition persists, the IDB module may require replacement.
