EOT Damping Command Boundary Reached Overview
NTC 0x0C6.0

FDD: SF027A

Description:

A diagnostic fault is triggered when the EOT Damping command reaches or exceeds the

firewall safety boundary.

Diagnostic Overview:

The EOT Protection Firewall applies a limiting boundary on the EOT Damping Command.  The NTC is only triggered to provide notification of that limiting has occurred during the current controller power cycle.  The safety limit value is conditionally applied based upon steering wheel angle and vehicle speed.  There is no debounce time allocated for the NTC (eg pass step, fail step).


Typical Fault Response:  

    • LOA Based Systems 

      • F3 

    • Non-LOA Based Systems 

      • F3 

Probable Sources (Most to Least Probable):

    • Systematic fault within the primary return command function 

    • Corrupted calibration of the EOTDamping firewall safety boundary

EOT Active Command Boundary Reached
Overview
NTC 0x0C6.1

FDD: SF027A

Description:

A diagnostic fault is triggered when the EOT Active command reaches or exceeds the

firewall safety boundary.

Diagnostic Overview:

The EOT Protection Firewall applies a limiting boundary on the EOT Active Command (eg software rack limiter command).  The NTC is only triggered to provide notification of that limiting has occurred during the current controller power cycle.  The safety limit value is conditionally applied based upon steering wheel angle and vehicle speed.  There is no debounce time allocated for the NTC (eg pass step, fail step).



Typical Fault Response:  

    • LOA Based Systems 

      • F3 

    • Non-LOA Based Systems 

      • F3 

Probable Sources (Most to Least Probable):

    • Systematic fault within the primary return command function 

    • Corrupted calibration of the EOT Active firewall safety boundary
