P1502 fault code

[JFP in PA]

I have never been a fan of the iCarsoft units, the constantly over promise and under deliver on capabilities, which they continue to say will be available in a future update that never seems to materialize.

Obviously, the best would be a legitimate PIWIS system, which is lease only and opens at $20K for the first year. And don't even think about spending your $ on PIWIS clones, many of them are incomplete, cannot be updated, and some can actually damage the car's electronics. So, unless you are willing to spend mega $, I would go with the Durametric software. Not as capable as the PIWIS system, but much better than a lot of companies selling "made for Porsche" standalone units that are mostly global OBD II junk with a couple of Porsche specific capabilities thrown in for a higher price than a global OBD II unit.

I'm trying to work my way through this while waiting for an auto electrician to identify a possible short. Any advice wecomed.

As I have said, I don't think adaptation is working. When the ignition is switched on I can hear and feel a rapid double click from the throttle body.

What I noticed is that if I clear the code I can hear and feel a single click from the same area so I took the TB off and observed when you turn on the ignition the TB flap does a rapid double click and stops slightly open. When I clear the code the flap closes.

The fuel pump relay has been replaced with a good unit as has the TB and I cannot see any frayed wires anywhere.

In the meantime, can anyone tell me what else is on that fuel pump relay circuit?

I can't see any point in swapping the ECU because I gather it contains the immobiliser key and I don't want additional hassles with that.

I've been trying to think of anything that happened prior to this problem and all I remember is 1) running low on fuel once but not running out and 2) the union for the washers broke spraying fluid down the side of the battery box. There are two unconnected connectors there - one yellow and one black. Anyone know what they are for?

There has been no water ingress inside the car.

Man, I wish I'd seen this before I bought an iCarsoft. To add insult to injury, I found an identical unit in the box containing vinyl seat covers (which the previous owner had gotten to cover the original drivers seat, seeing as how its leather was in sad, sad condition). The other iCarSoft "Porsche-specific diagnostic unit" was under the vinyl covers. It was too late to return the first one, of course. So now I'm stuck with two of them. Maybe I'll take them to a meet and see if I can sell them, along with the vinyl seat covers. In the meantime, I'm psyching myself up to spring for a Durametric. Live and learn.
