Eliminare Errori DTC dalla mappa su EDC15

[Sasquatch]

Come da titolo mi piacerebbe approfondire la cosa , in rete ho trovato questa descrizione

 

12. EDC15 Non PD Error (dtc) removal

To delete a fault code you will need to find it first.  To find a fault code in your file, use the search function in Winols. For ‘P’ codes such as P0101 it is best to set the file view to 16 bit, FF view. Then use search/Hexadecimal 0101. For VW customer codes such as 16485 it is best to set the file view to 16 bit, decimal (255) view. Then use search/decimal 16485     Deleting error codes depends on understanding the error code layout. Early non-PD ECU’s have codes laid out like the example below. The example is based on Air Mass Meter (AMM or MAF) error codes.   EDC15 non PD fault code layout.   e.g MAF codes   The error codes are arranged in a group of 8. Bosch number these 0 to 7. This does not mean 8 error codes will be present. It means up to 8 error codes can be present.   In this example below there are 7 error codes present. The 8th slot is unused (00000).   The next obvious block is for the ambient or environmental conditions. This is made up of 5 codes.  Similar environmental condition codes are used for many error code blocks so you should find them easy to recognise once you have found one block of 5.   The arrangement of the MAF error block is shown below. Messages are either 16 bit or 8 bit. Message descriptions are my best guess.   16 bit               8 bit     Description of message 00000              000      LMM  7:COM,6:FUE,5:MIS,4:CAT,3:EGR;2:DIA,1:MIL 1-0:PRI 000      Fault entry count start value 49920              000      Heal entry count start value 195      Scrap/not used 17552                          P1144 Mass or Volume Air Flow, Circuit Open / Short to Ground 17553                          P1145 Mass or Volume Air Flow, Circuit Short to B+ 17554                          P1146 Mass or Volume Air Flow, Circuit Supply Malfunction 17554                          P1146 Mass or Volume Air Flow, Circuit Supply Malfunction 17552                          P1144 Mass or Volume Air Flow, Circuit Open / Short to Ground 17553                          P1145 Mass or Volume Air Flow, Circuit Short to B+ 16485                          P0101 Mass Air Flow (MAF) or Volume Air Flow (VAF) (G70), Circuit Range / Performance 00000                          Pxxxx   Unused 03938                          Environmental condition 1 03939                          Environmental condition 2 03937                          Environmental condition 3 03844                          Environmental condition 4 03888                          Environmental condition 5 00048                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable 00048                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable 65535                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable 65535                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable   How to delete/remove a dtc.    Each error code has one or more Fault count and Healing count for debouncing the error. In the example above there are 4 of these. Changing the Fault count and Healing count will prevent the error from showing. Fault counts should be changed to 65535 which means that the fault should never log. Healing counts should be changed to 00000 which means that a fault will heal instantly.   So;   00048                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable 00048                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable 65535                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable 65535                          Fault count 00048                          Healing count 00017                          Time/Event driven-deletable   Should be changed to; 65535                          Fault count 00000                          Healing count 00017                          Time/Event driven-deletable 65535                          Fault count 00000                          Healing count 00017                          Time/Event driven-deletable 65535                          Fault count 00000                          Healing count 00017                          Time/Event driven-deletable 65535                          Fault count 00000                          Healing count 00017                          Time/Event driven-deletable   Now the 8 MAF codes will never log a fault (65535) and if a fault is detected it will instantly heal (00000) It is important to change all of the error & heal pairs.  If they are not all changed a different fault may be logged or the MIL light may come on after driving for some time.   If you use this method and the MIL light comes on after driving. Check this. Make sure that the red values below are set to ZERO (000)   00000              000      LMM  7:COM,6:FUE,5:MIS,4:CAT,3:EGR;2:DIA,1:MIL 1-0:PRI                         000      Fault entry count start value 49920              000      Heal entry count start value 195      Scrap/not used   If you are still having problems. Try setting the ‘Time/Event driven-deletable’ values to 00000   With luck you should now have deleted your error codes.

 

da quanto ho capito si alza il valore a 65535 del bit corrispondente al DTC , e si azzera quello subito dopo mentre il 3° bit deve essere 17 se non 000000 

qualcuno ha conferme ? suggerimenti ? o ha effetuato test sulla propria edc15 ?

 

fatevi sotto

speriamo che ti diano una mano, bella discussione ai guru su dateci una mano, grazie

[sisco]

provate a guardare anche quì

[Sasquatch]

grazie mille sisco mi ci fiondo

[lupotto]

ti ringrazio sisco per avermi rinfrescato la memoria, infatti qualcosina me la ricordavo, grazie

[Sasquatch]

resto nel buio non ci arrivo , domani con calma ci riguardo anche se sono codici vag

[Sasquatch]

allora provo a mettere qualcosa , premetto che non sono minimamente sicuro di quello che ho fatto e quindi vi chiedo se qualcuno puo' darci un'occhio e mi possa dire qualcosa , il file e' di un kia edc15c2 almeno credo sia c2 , ho cercato il P0403 e disabilitato  tutta la sequenza di quegli errori ossia credo anche il  402 etcc .....ma appunto credo , sperando di aver capito il concetto

non so se sono info giuste , ma leggendo in rete tale sistema funziona solo con le vag  sulle altre edc15 a quanto ho capito il sistema e' diverso e somiglia alle edc16 ossia vi e' uno start  error path e uno start error block ,e quindi va' trovato  ma l'errore va' disabilitato come sulle vag  , a qualcuno risulta ?

io sulla mia la zona dtc l'ho identificata, ma se ti dovessi dire il calcolo per cancellare un preciso dtc non te lo so dire
