Can you guys please help me??? OBD Renault Clio help needed!
Right, I have spent the last two days trying to find out what type of OBD my 1999 Renault clio 8v spi uses. It is a UK car. It has a 16 pin connection under the ashtray. It has connectors in pins 1,2,10,12,13,16.
I really do not have a clue.
Thanks for reading,
Not EOBD, almost for sure. EOBD not required for Europe cars...

so hard telling what the protocol is. Can't access my company's internal web site where a list of European vehicles that were tested are listed so can't look to see if a '99 Clio on it. Since OBD II not required until after IIRC 2001 (for gas, and even later for diesel) vehicles in Europe and I was only interested in testing/verifying OBD/EOBD II compatibility might not have probably didn't even bother testing any '99 Clio unless a contact in Europe had one handy as a personal vehicle. Most cars tested were newer models at dealerships or vehicles were rented or had access to at companies and their fleets of vehicles.

And for a Clio 1.2 16V - 2007
what protocol is used ?
it has connectors in pins 1,4,5,6,7,14,15,16
I'm using a CAN interface (MCP2551 - 18F258 - RS232) connected to pins 6 - 14 (CANL - CANH) at 500kbps.
i don't understand the frames recieved
can anyone help me with some info ?
Are you trying to interpret Can frames using a scope or...
do you have the frames showing the numbers like:

or are you trying to decipher the electrical wave forms?
2007 vehicle probably CAN but Europe/UK like to use 250KBS not 500KBS. 'course, 500KBS it may be. And 11-bit or 29-bit Id.
The J1962 pin descriptions for pins: 1,4,5,6,7,14,15,16
1 = single wire can
4 = chassis ground
5 = signal ground
6 = discretionary (GMLAN HS CAN High)
7 = K Line of ISO 9141-2
14 = discretionary (GMLAN HS CAN Low)
15 = L Line of ISO 9141-2
16 = unswitched vehicle battery positive
Based on pins present in connector I'd say vehicle could use up to 3 protocols: high speed CAN, single wire CAN, and ISO 9141-2.
OBD II commnication is most likely on the high speed CAN bus.
