i can connect to others ie 7.3.1 but not iso codes are ok but when connecting it disconnects with no error

..........Getting started with ELM 327 interface
What about airbags? Must modify the ELM interface? (Pin 3)NOTE: You have to solder a short wire between pins 1-7-9 of your interface's OBD connector in order to connect to ABS and Power steering ECUs. This is not required if those ECUs are on the CAN network. The EPS of Fiat Punto MK2 for example is on the can network.
Airbags are not supported by the ELM interface!nissanek_3 wrote: What about airbags? Must modify the ELM interface? (Pin 3)
