How to solve KTag failed to read EDC16C35

标签：

Just got the new ktag clone from China.

First I tried ECU EDC16C35 with CMD Probe, but Ktag didn‘t connect to it.

What I did for KTAG connection:
I tried kTag with CMD Probe and with direct connection (soldered) to the pcb.
I tried different cables for connection.
With external power supply to kTag and without (only usb).

Just for testing I tried the same with VAG EDC16 ==> same result.

Both ECU‘s are working (connection over pin out is ok).
KTAG V2.13 PCB:

Optional reasons & solutions:

Solution 1:
BDM Port is broken. (send back to the seller for repair)
Even genuine tools don‘t read.
Other EDC16C35 working fine

Solution 2:
Buy a good quality K-tag adapters, from wobd2

Solution 3:
can be caused by bad K-line, when also can´t do other EDC16........
Or BDM don’t work
I think you have to rework your clone or try slow communication
