GM ALDL Feilsøking

[ricmik]

Hei! Jeg har et spørsmål jeg har stilt på engelsk tidligere, så jeg håper ikke det gjør noe at jeg sender deg spørsmålet på engelsk.

 

Håper noen kan hjelpe meg!

 

I have a question regarding my Chevrolet G20 ’88.

Here’s the cars data:

 

Chevrolet G20 Van ’88

6.2L Diesel

Automatic transmission

Mileage: somewhere around 65000

A/C and Cruise Control

 

Questions:

 

The ”Service engine soon” light is constantly lit. When I try to short the ALDL to get an error code, I only get the “Diagnostics mode” code (1 pause 2).

 

Anyway, when I short the ALDL, I can hear the glow plugs relay click (I suppose it should do so) – in addition to a weird fast clicking noise (like a relay is being turned on and off repeatedly). Is this normal?

 

I have a light bulb hanging behind the instrument panel with wire colors: gray/pink-black (pink with black stripe). There’s also a plug with 4 contacts; wires: dark blue/yellow – brown/light blue.

 

What are these for?

 

Is it an easy way to check that the A/C compressor is working? I can't get any cold air out of the vent.

Det med A/C'n er vel bare fordi det ikke er mer gass igjen? Dra til noe autorisert noe og fyll på mer gass til kompressoren.. Mest sannsynlig det..
