Hi Guys,

As far as I understand from the below topics:
http://nefariousmotorsports.com/forum/index.php?topic=2973.0
and
http://nefariousmotorsports.com/forum/index.php?topic=915.0

Permanent solution for "Death Code" (DTC 16985) doesn't exist and this error can appear in any chipped ECU with immo-off at any time. So in order to avoid stop the car at some place with the death code owner should have spare ECU with same flash-file and EEPROM. According to above in order to avoid this error we shouldn't defeat immo (use immo always after chipping the ECU).

Is my understanding correct?

Thanks in advance!

You can send me PM with the way

Or maybe only some ECUs affected?

Hi Daz!

What do you mean under "corrupted file" eeprom or flash? So if I upload eeprom and flash-file with correct CS in that case I'll never have this error? How can I check properly CS?

this thread has so much confusion in it.

The deathcode is set when the engine fails to start due to a flash checksum error. The error is recorded in the eeprom and must be manually cleared. I flashed 100x to try to clear it, but in the end I had to manually remove it from the eeprom, and then write it back to the ecu. It will come back after a few start cycles IF you don't fix the problem itself, which is a bad checksum in the flash.

100% correct  , it normally happens when you modify  a tuned  me7 file into ols which messes up CHK  .  lines 1 and 2  near the end 003  in the 95040
