diagnostics port on the 309 GT ?

[amilo123]

I saw that under the hood there is a diagnostics port, someone told me that this car has a computer and can be diagnosed like a modern car, is this true?

I know that the peugeot dealership can connect to it, but what information can they tell me? are 25+ euro worth it?

Well, be careful, this is nothing compared to recent cars. It's just a basic diagnostic port which works with a very basic code reader anyone can buy on the net. So it has nothing to do with computer systems. All injection 309s with a catalytic converter are equipped with it I think.

[amilo123]

well i don't have injection...so what other info can it provide?

[alargeau]

Well, so how does the connector look like?

[thefunkyboy]

It is a useless wire ^^ I think I will remove it on the engine I am repairing

[amilo123]

it has three connectors. If you want i can go to the car and take a picture,

So it's a port with three connectors. What colour is the port?

[amilo123]

brown

Oh okay, it's not a diagnostic connector, it's for the air conditioning.

[amilo123]

Oh okay, it's not a diagnostic connector, it's for the air conditioning.

but it doesn't have AC...

[amilo123]

i read in the manual that one of it's uses is to adjust the engine timing, could it be that it's all it does?

[thefunkyboy]

To adjust the engine timing, generally you put the instrument directly all around the electrical wires

[amilo123]

yeah, i know, but maybe this car has a better method?

[thefunkyboy]

I don't know. All the mecanics who did it on my 309s never use this connector

[alargeau]

but it doesn't have AC...

All 309s have it, whether they have A/C or not because it was much easier to manufacture it like that. When they don't have A/C the connector has two wires connected to each other.
