Gen3/tasks/TEST-BRAKE_ALL_STIFFNESS-PRESSURE-DELTA
Runs brake stiffness individually for all wheels, and pass/fails on a threshold of pressure discrepancy, pressure value, or dead travel stroke. If executing with DIAG_LINK_ACTIVE then EPBs will release one at a time, which is required if check_swapped_rear_lines is true.
Select your vehicle’s hardware to see task details, requirements, and inputs. Availability is confirmed after connection.
WARNING Test releases parking brakes one at a time. The vehicle may shift! Make sure the vehicle is on a flat surface or a lift, and surrounding area is safe.
