Technical Where is the OBD II connector in my Marea Weekend?

[TBMonsen]

Hello

Where is the OBDII connector located on my 1999 Fiat Marea Weekend 2.0 20v 155hp ? They tell me it's supposed to be "close to the drivers seat"... any clues?

I have started to build a fault code reader/rs232/obd converter at work for my car... that I haven't got home yet from the dealer. Will be arriving tomorrow

Thanks for a great forum.

"5-Data link connector (DLC)"

I'm so sorry. I see now in the "sticky" at the top page where it (probably) is located. Is this the one I am looking for? Number 5 in the picture?

on the 155 if you have one should be behind the fuse box panel under the steering wheel on the right..... if not you dont have OBDII like me and you need to use the sockets under the bonnet

on a 99 2.0 model you will have 2 diagnostic ports. both of them will be the fiat 3 pin type.

to connect the 3 pin fiat connector to a 16 pin obd2 connector you need 4 lengths of wire. use 3 lengths of wire to connect the 3 pin connector to the obd connector. also use 1 length of wire for power to the obd connector.

on the 16 pin obd2 connector use the following pins
4- chassis ground (connect to ground on 3 pin connector, or any good chassis earth)
5- signal ground (connect to black wire pin on 3 pin connector)
7- k line (connect to white wire pin on 3 pin connector)
16- 12vDC (connect to battery positive terminal)

Thankyou!

I have ordered the components today, and will mostl certainly be able to start the buildup this weekend. Will come back to you with my findings.

Perhaps I can help you guys to avoid having to go to a garage getting diagnostics for outrageously high £30 that I have seen quoted on this site.

Cheers,

Tomas
