Are all OBD2 ports the same?
All OBD-II pinouts use the same connector, but different pins are used with the exception of pin 4 (battery ground) and pin 16 (battery positive).
What’s the difference between OBD1 and 2?
In like manner, OBD2 is an advanced technology improved from OBD1. Thus, OBD2 provide better and more standardized vehicle protocols and system checks data. OBD1 needs corded connection while OBD2 can be connected hands freely via Bluetooth or wifi.
What OBD protocol does Ford use?
SAE J1850 PWM Diagnostic bus/protocol used mostly on Ford. Uses pins 1 and 2, communication signal is differential and it’s rate is 41.6kB/sec.
Is my car OBD1 or OBD2?
There should have been a tag underneath the hood that specifically determines the sort of OBD the car has. The second method is already described several times above. If your car was manufactured before 1996, then it has an OBD1 scan tool and if it was manufactured after 1996, then it uses the OBD2 scan tool.
What OBD protocol does BMW use?
OBD-2 compatibility list
| Model | Engine | OBD-2 Protocol |
|---|---|---|
| BMW 328CI | Gasoline (231 HP) | ISO 9141-2 |
| BMW 328i | Gasoline (191 HP) | ISO 14230-4, ISO 9141-2 |
| 2.8i, Gasoline (193HP) | ISO 9141 | |
| BMW 330 | 3, Gasoline (231HP) | ISO 9141 |
What’s the difference between ISO 9141 and OBD2?
Not only that, the biggest difference is that this OBD2 protocol has no pin 10. Next, ISO 9141-2 is an old protocol that is mostly found in European vehicles that were built between 2000 and 2004. You will find this protocol on some Chrysler and Asian vehicles as well. It uses pin 7 and pin 15 is optional.
Which is supported by my Vehicle, ISO 9141-2?
Next, ISO 9141-2 is an old protocol that is mostly found in European vehicles that were built between 2000 and 2004. You will find this protocol on some Chrysler and Asian vehicles as well. It uses pin 7 and pin 15 is optional. The operating speed is 10.4 kb/sec and this protocol uses asynchronous serial communication.
Which is ISO 9141 or ISO 14230 KWP2000?
If the connector has pin 7 and an optional pin 15 then it could be ISO 9141 or ISO 14230 KWP2000. The metallic contacts inside the pins are 4, 5, 7, 15, (plus 16). If there are both pins 14 and 6 in a connector with material contacts 4, 5, 6, 14 and 16 then it’s an ISO 15765 CAN protocol.
