Who needs this CAT C15 quick stop manual
Mechanics and workshop owners need this manual when a C15 MXS truck engine logs PID 0084 FMI 14 and the service brake application is associated with a vehicle deceleration rate above the programmed Quick Stop Rate. The extract states that customer passwords are required to clear this diagnostic code and that the code does not represent an electronic system fault.
The diagnostic notes identify one likely cause for excessive occurrences: the Quick Stop Rate parameter may be set too low. The note also states that load can affect this setting because a vehicle operated without a trailer or without load can stop faster than the same vehicle with a heavy load. The ECM records engine speed, vehicle speed, throttle position, cruise control status, clutch switch status, and brake switch status when the condition occurs.
