WHERE IS YOUR ECM CONNECTION

SEE POWERTRAIN CAN AND POWERTRAIN CAN ENABLE

AND DOES YOUR MPVI CONNECT IN-VEHICLE,, DO IT FIRST BEFORE DO IT IN BENCH

I've tried several times, but it hasn't worked for me.

Where can I find POWERTRAIN CAN and POWERTRAIN CAN ENABLE in any CCM?

BCM, serial data gateway, ECM, and TCM all work on DPS and SPS2 without any problems.

Only on HPT, I GET Msg Detect protocol failed

If your scanner communicates and dps works too then your hptuner interface is banned

I received the device and tested it, but it's not working; I'm still getting the same message.

Detect protocol failed

I'm still looking for a solution or searching for Pinouts about my MP3

what it reads and where it retrieves data from.

I await your help. Thank you
