Question

Does anyone know if there is a diagnostic plug on a 1994 Peugeot 605svti and if so where it is thanks?

Answer 1

There is on the petrol models, not on the diesels.

On the 2.0, it's under the right hand side of the dash next to the footwell side panel.

On the 3.0, it's in the far left hand side of the dash behind a removeable panel below the top of the dashboard.

In either case, you'll find a 30 -pin connector (horizontal on the 2.0, vertical on the 3.0.

To access fault codes, proceed as follows:

connect an LED to +12v, and the negative lead to terminal C3.

You'll then need a switch between terminal C2 & earth.

Switch ignition ON

Check that malfunction indicator light illuminates

Close the switch for between 2 & 5 seconds

LED or MIL will now flash trouble code 12

Each trouble code consists of two groups of one or more flashes

Long flashes indicate 'tens'

Short flashes indicate 'units'

A short pause separates each flash

A long pause separates each trouble code

Repeat operation. Note trouble codes.

I have the list if you can give me the trouble codes.
