NTC Temporal Monitor Run Fault
Overview - NTC 0x041

FDD: ES005A

Description:

This diagnostic is responsible for detecting Temporal Monitor Run Time faults.

Diagnostic Overview:

The temporal Monitor Function monitors the POE output of the Temporal Monitor IC (A4412) and if the POE is low, A SPI message is sent to the IC to check the type of Fault (WatchDog Fault or Non-WatchDog Fault). This Fault is captured by NTC 0x041.

Typical Fault Response:

- –F3 Failure

Probable Sources (Most to Least Probable):

- - •Temporal Monitor IC(A4412) fault.
  - •WD_Monitor pulse fault.
  - •POE fault.

NTC Temporal Monitor Init Fault
Overview - NTC 0x040

FDD: ES005A

Description:

This diagnostic is responsible for detecting Temporal Monitor Initialization faults.

Diagnostic Overview:

The temporal Monitor initialization has a sequence of events. Faults at any one of these events are captured by the NTC 0x040. The sequence of events are monitored by a counter variable TmplMonrInitCntr.

Typical Fault Response:

- –F1 Failure

Probable Sources (Most to Least Probable):

- - •Temporal Monitor IC(A4412) fault.
  - •Temporal Monitor SPI fault.
  - •WD_Monitor pulse fault.
  - •POE fault.
