IDB_a029_pressureSensNotCal

The Integrated Dynamic Brake (IDB) pressure sensor offsets are not calibrated.

Live incidence rate

<0.01% (Extremely rare)

Vehicle messages

Power braking assist reduced
Braking may require increased effort

Impact

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.

Description
