Default Winkfp signature check failed when flashing ZBE controller

I tried to update my ZBE controller in WinKFP and it stopped working after I flashed it. When I flash the module it completes 100%, then I get this error message:

Error 211
Code Level Module Procedure Index Text
2086 PABD ZBE2 PruefeSignatur 2493 Signature check failed 11FLASH,
NG_SIGNATUR_PRUEFEN (Programm)
ERROR_FLASH_SIGNATURE_CHECK
2086 Error COAPI2.CPP coapiRunCabd 6 Signature check failed SG_PROGRAMMIEREN
2086 Error COAPIKF.CPP coapiKfProgSgD2 19 Signature check failed

I’m using the latest daten files from ISTA-P 3.66 with k+dcan cable and 15A battery charger. I was able to flash my Combox, PDC, and DWA (these were retrofits) without a problem, but the ZBE keeps giving me the same error. I tried programming the ZBE in ISTA-P and I got the same error message. The ZBE shows up in INPA UIF with job status “OKAY”. Any ideas on how to get ZBE working again?

Default *** solved ***

The problem was with the firmware in my K+DCAN cable. Apparently most of the cables have a firmware bug that causes the wrong data to be written on some of the ECU's. I updated the firmware on my on my K+DCAN cable using the instructions on this website and was able to program my ZBE without any errors.

You will need to buy an AVR programmer to update the firmware.
