Mazda 5 with RF7P ecu ...

[levisdj]

I have this Mazda 5 2.0 diesel equipped with Denso RF7P ecu, I connected KTAG read all well, but when writing I get error, I must add that the car came in for DPF removal... as error I get "Communication error with the ECU controll all connections" ... that happends after the software tries to identify the ECU ... I must add that I triple checked connections for reading and writing as the software suggests using the ribbon cable, 144300T104 for writing and 144300T105 for reading.Voltage up to 13.8 V ... any idea ?


Ktag version 2.23
