EA4-x NTC 0x0A2(0) HighFriction
NTC Overview
NTC 0x0A2.0 High Friction NTC
(Reduced Performance)
Description:
•This diagnostic logs a fault when the system friction value exceeds a calibrated threshold
Diagnostic Overview:
•Friction learning is very important function which helps us compensate for current friction through Hystersis compensation
•When the estimated friction is above a specified threshold, a diagnostic flag is set to warn the driver of high friction within the system
Typical Fault Response:
•Response for this diagnostic is F3
•The fault is latched with ignition cycle
Probable Sources
(Most to Least Probable):
•Environment conditions causing rust formation and enhancing internal friction of the system
•High friction due to unwanted accumulation of materials/debris
