Question: Edc17c59 Vauxhall zafira, following pcmtuner pinout and trying to read on module 53 tc1767 but no communication, am I missing something?
Solution:
well module 53 is BSL so unless you have opened ECU and connected boot pin then it wont read or write.
Use module 71 in bench mode.
Feedback:
Got it to read in the end, was trying in tricore but changed it to Bosch med17 worked a treat.
