Thanks, this gets me further along. I have found the diagnostic connector. But, what I really need to know is how to retrieve a code. Does the electrical troubleshooting manual tell you how to retrieve the codes? In the Bosch fuel injection manual it says there is a connector on the fuel pump relay which will accept a fuse to retrieve codes, and gives the procedure for doing so.
I will look at the fuel pump relay to see if it has the connector as Bosch says it should.
Does anyone know how to retrieve the codes without the diagnostic equipment?
Thanks again and have a great day,
