Hello,

I have problems to make an communication to the motor ecu.
In the car and also on my bench...

Peugeot 206 1.1
Mj. 2000
IAW 1AP.83

Does anybody knows whats faulty in the ecu? Software??? because I could not measure a faulty hardware.
I dont believe that is an IMMO problem because in the car is on Pin 13 and 35 the power supply OK and the BSI recognize the key.

Connection on my bench:
12V --> Pin 13, 35
ground --> Pin 36, 54
K-Line --> Pin 31
L --> Pin 12

You can read this ECU only when it receive correct immo code,so if all power supplies are ok you have immo problem.

Ok! Thank you!

I thought also when the immo code is wrong, you can still read out the faultcodes.

So it should be solve when I make immo off?

Make sure to load check power supplies to ecu , not just measure 12v supply , not good enough ! Often these wires corrode but will still give 12v but cannot carry current. Use a bulb and earth one side of it and use the 12v that is supplying your ecu wires to other side of bulb. Should light brightly .This is my guess that you're problem is .

Problem solved!

I had made immo off and now its OK!
