Have search the net and read everything i could about the motronic pinouts regarding ac to AAN (UrS6 -95) |
It looks like this information regards motronic:
6/55-Connection to A/C Control Head -E87- G/Y - Used to shut off A/C for up to 12 seconds when throttle is opened rapidly at speeds under 7 kph and shut off A/C for up to 3 seconds when in first gear and throttle position is at 65 degrees or more (full load) Ref: VAG143.
41/55-Signal from A/C control module -W/W - Tells the ECU whether the A/C compressor is on or off. This signal used by ECU to increase idle speed through ISV control when A/C compressor is activated (actually just maintains the idle speed when the extra load from A/C compressor is added to the system during idle)
When messauring the w/w cable in the blue t6 socket it produces 9,5 voltage with ignition on, when adding snowflake (ac) it goes to ~9,8 V
And the G/Y is 0V vs 3,5V when AC is off/on?!
Is it suppose to be the pin 6 that activates ac clutch and communication to my vems ac setting? Anyone that have done this?
Feels a little waist to change to MaxxECU just to get this working...
See LINK for vems information regarding AC
