NTC ECU Identification Fault
Overview
NTC 0x0B9

FDD: ES011A

Description:

This diagnostic is responsible for detecting incorrect ECU Id either on the primary or secondary ECU.

Diagnostic Overview:

The Dual ECU Identification Function shall indicate a negative result if either of the following conditions are true

  • -Primary ECU Id is either 0 or 3 

  • -Secondary ECU Id is either 0 or 3 

  • -Primary ECU Id is same as Secondary ECU Id 

  • -Valid SecdryEcuId is not received in a specified time window 

  • -ECU Communication time out occurs when trying to communicate with the secondary ECU 

Typical Fault Response:  

    • F3  Failure
       

Probable Sources (Most to Least Probable):

      • Communication Time out 

      • Broken pins to read the ECU Id or either ECUs 

      • Same ECU Id for both ECUs (Pin connection mismatch)

Instructions for Functional Design Package Peer Review




PRE-MEETING


Function OwnerConfirm that requirements are reviewed and approved PRIOR to the FDP peer review

Function OwnerStart with latest version of the template for any "first reviews" - Continue to use existing temmplate for re-reviews

Function OwnerProvide the functional design package (changed documents) to the invited attendees 1-2 working days in advance of review

Function OwnerNotify the assigned peer reviewer and make sure they are prepared to do their function in the meeting

Function OwnerIdentify necessary attendance and invite to meeting

Function OwnerComplete the "Author" column information for sections 1 through 3 prior to the review

Function OwnerComplete the attendance invitation list in section 5

Function OwnerFor Re-reviews only: Complete the column "remarks by author" to identify actions taken to address items found in earlier reviews.



DURING MEETING


Function OwnerPresent document changes to the review team

Peer ReviewerCapture attendance of the review

Peer ReviewerCapture actions and issues in section 4. Identify issue summary, Document type, Reference (Requirement ID, section number, etc), Defect Type and indicate status as "OPEN"



POST MEETING


Function OwnerFollow up on all "open" items. Update "Summary of Resolution" to indicate what was done or decided.

Function OwnerSchedule follow up review OR review open items with peer reviewer and obtain agreement to close

Peer ReviewerClose change request in system and confirm all associated tasks are complete. Upload peer review checklist (this document) with any FDP updates

1Section 1: TECHNICAL CHECK













1.1Confirm that all signal inputs into the FDP (Functional Design Package) are contained within and exactly named as the "Available_Nexteer_Signals.m" states.YesYes











1.2Confirm any removed signal inputs from the design have been removed from the "Available_Nexteer_Signals.m" file.YesYes











1.3Confirm all signals and parameters (outputs, calibrations, constants, non-volatile memory) used in the *.m file and the design conform to the AutoSAR naming convention documentation.YesYes











1.4Confirm *.m file has been provided to the "Available_Signal_Names" Author.NANA

Darryl's tool sweeps up all the signals








1.5Confirm Electrical Systems interface map is updated to reflect the FDP (signal IO)NANA











1.6Confirm that Static Register evaluation has been completed and updated for any register data that is written to.NANA

No Registers








1.7Have calibration default values been reviewed for correctness?NANA

No Cals

3.01Have functions depending upon system state been reviewed for need to be executed at the 2ms rate to avoid system lag issues?YesYes











3.02Have all diagnostics (NTCs) been confirmed to show logic to invoke a diagnostic "PASS" for control of the status byte at the customer level.YesYes











3.03Has the requirements traceability steps used the RMI steps as defined in the FDD authoring spec to generate the traceability report?YesYes











3.04Has the requirements traceability report been verified to only contain ONLY requirements from the FR.YesYes











3.05Confirm that all PIM that does NOT have an initialization value of zero is initialized in an INIT function.YesYes











3.06Confirm if NVM is used, the NVM is defined in structuresNANA
