Hello Klaassen

With this ELM Interface you can not read a Body or Dashboard , right ?

Remove the yellow marked Resistor and your ELM can read this Controls

Hello everybody, can someone take a look at my ELM327 ?

I bought a ELM327 1.5 a (alu) to reset my service interval on Fiat Bravo 2 1.6 jtd.

All connection tests are OK and i can connect multiecuscan to my engine but i cannot connect to service interval reset. Multiecuscan alway's ask me to check my connection parameter or cable.

I have read lot of forums that's sayind to remove R04 resistor but my ELM is different.

I send you pictures :

Hello Aulecuver80

Resitor R4 its Wrong , you must Remove only the Resitor R2 (1200)
then you can read with your Interface the CAN Protokolls with Multiecuscan.

All other option work without problem.
