Default Re: DTC (OBD Error Code) Deletion/Removal Strategy

so looking through the downloaded PDF and the first post... im still a bit confused as to how to locate the DTC for Evap Purge canister.

I have an S54 Swap in my 2003 E46 ZHP

currently i get a CEL p2402 for Evap Canister evaporative system leak detection pump control circuit has a high voltage signal return


in my last MSS54 DME I had someone code out that CEL with i HEX but in doing so then my Cruise control stopped working.

I got a new MSS54HP DME for shift lights but now that CEL is back. Id like to remove it again properly and still keep my cruise control.

i have a full 1MB and partial 64kb BIN file on hand that I used BMWFlash.exe to get.

I dont see after skimming through everything where it says the DTC for this is located at address ......

Why did you get a mss54hp just for shift lights? The mss54 can do shift lights aswell.

For dtc removal you first need to find the dtc number for the code you are getting. If you use bmw logger to get the code it will show you the code error number in decimal.

Then lookup the hex string for the dtc number you find in this thread
http://www.m3forum.net/m3forum/showthread.php?t=458115
Example for dtc 1 the hex string is 01282806060606000102032803FF

After that search for that hex string in your 64kb bin file. Make sure you are searching for hex and not text. Then replace the hex string numbers with 00’s

the MSS54 DME I had unfortunately fell into the one specific variant that didnt support it according to the list in the shift lights thread.

http://www.m3forum.net/m3forum/showthread.php?t=465553

Variant - 211322000701 MSS54 unavailable

Terras Shift light checksum tool would show that option disabled greyed out. using the ECUWorx tool did allow me to set it but it never worked in my cluster.

switched to an HP DME and Terras tool worked and ECUWorx tool worked and shift lights worked.

It could have been something else but I didnt want to over think it. i sold my DME ofr $275 and paid $350 for an HP DME variant so it wasnt too terribly bad.




thank so much for the crash course and I cant wait to take a dive further now.

I posted a link but realized it didn't contain that code conversion. Just use bmw logger to find the dtc number that way you know you are deleting the right code.

DTC 0901 - 1101 - 1301 - 1501 - 1701 - 2101 - 2401 - 2601 - 2801.xdf
and
DTC 1801 - 1901 - 2001 - 2501 - 2701.xdf

Base patch data set for 2801 and 2501 as it is what I have. If patch data has a mismatch, then you will need to go into the patch and apply your base data from the tune you pulled for your own backup. Feel free to share/edit etc.

Change .xlsx to .xdf

Created this using the DIS descriptions. Sort by Category. I added a category for common DTCs to disable for engine swaps (into non-E46) Enjoy. Can't wait to finish my E30 S54 swap.
