I can't connect to 159 1.9 jtdm ECU. Everything else works, even automatic gearbox which is k-line too. I have ELM327 V1.5 bluetooth. In ECU connection initialization, I get ELM327->ECU connection error.
What I have tried:
Other Smartphone app- I can connect to ECU and read live data, however it doesn't recognize my error code and lit mil light. This proves that ecu:s k-line is not dead
Other ELM327 bluetooth adapter
Taking battery terminals out for 30 min
Diffrent baud rates
Would I have better luck with VagCom cable? For me, it seems that ecu goes to sleep too early and thus doesn't connect. Or the protocol is for some reason wrong. The smartphone connects with ISO 14230-4 KWP (fast baud init)
I appreciate every help offered.
