Codes 709 & 1299

[srfrdrew]

I've finally given in and got myself a Durametric.

 

Codes I've pulled off my 2004 Cayenne S are the following:

 

709:  Sun Sensor - Open Circuit/Short circuit to ground

 

I have looked around for this and have found no info for code above nor a part number or replacement for it?  - Ideas?

 

 

1299:  Gateway - Please read out fault memory, test conditions are not-completed, fault is currently active and is not causing a DTC light

 

I have found, again, very few explanations on this as well.  My be related to AC and or Blower Motor - Ideas?

Anyone?

709 code: i'd think you have a defective or disconnected Sun sensor, which was called "Solar Sensor" in model years up to 2011. its a plastic thingy sticking out from the middle of the dash.

I would erase the codes and see if they come back, try to find a PIWIS to be sure.

Does anyone have a DIY on access, replacement and/or part number on the Sun "Solar" sensor?

I think I would take RFM's advice and clear the codes (see if they come back) before buying any parts.

The CAN gateway may need to be reset. To reset the CAN gateway take the key out of the ignition and remove fuse #40 for at least 10 seconds. The fuse panel is on the left side of the dashboard where the dashboard meets the door panel. Re-run the Durametric and see if the faults come back.

A BIG THANK YOU for this.....  I had some recurring gateway faults that were lingering from a failed battery.  I pulled both fuse 40 and 19 to be safe since the comfort module was also flashing codes.   So far, so good.
