Re: Bosch EDC15/ Suzuki Grand Vitara HDI

Hi
I am trying to connect alex pepers obd-2 interface to a Bosch DDE4
which I thought was an EDC16 but some places on the internet say it
is a EDC15.

the engine is not in the car and the wiring is not connected to any
diagnostic plugs ( BMW or OBD)

I have connected the white/violet from connector 4/32 to the K-line
but I still cannot get it to connect

I have also tried tying the k+l lines together
all I can get after the KWP trys to log-on is

sync 00 w1 00
00 w2 00
00 w3 00
addr FF w4 00

any one any ideas?
oh the engine is a 3.0 d out of a 330 touring 2001 if that helps
