Multiecuscan

hello
i have downloaded the multiscan 1.7 feature and configured my KL 3PIN INTERFACE
i have a gtv 18ts 16v from 1998 when i connect the interface on pin 3 it can find the airbag module and i can read the codes
but to connect to the enginemodule on the onmodifided kl interface it can"t find the engine module and can't connect to the ecu
i have also an ELM 327 INTERFACE but also here when i adjust the settings it want connect to the ECU
somebody an idea where the problem is

regards

Hello

Where is your diagnostic connector to the ECU to read?
I believe the engine ECU of the engine compartment to the passenger compartment to the wall
relatively centrally in the engine compartment

You must also use the respective diagnostic connector to the 3 pin adapter.

All older cars have 3 pin connector for diagnostic. Each ECU has their own connector.
So for example 3 pin engine ECU connector should be behind the engine, below the wind screen as Alfaeddy wrote.
Airbag 3 pin ECU connector is in general in glove box compartment, or in that passenger area (on some models in the dash).
And ABS 3 pin ECU connector is in general behind the battery, close to shock absorber.

Always keep in mind that when you connecting to 3 pin connector in general you need KKL 409 interface without modification and 3 pin cable.
