:( Please help!!!

I get the following error codes in my Boxster's tiptronic fault memory when I hook up the PSII to it. Any ideas of what's causing this?

56 Instrument cluster activation

22 Load signal <-- DME CU

I'm getting the following errors on my instrument cluster due to this:

Tachometer, speedometer, odometer do not turn on while everything else still works. The lights that tell you in which gear you are are flashing between "D" and "4" rapidly.

Please help!!!

My local dealer...

What could cause those fault codes?

Since I replaced the engine, the instrument cluster has been acting weird.

It worked fine, then the tach, odo, and speedometer stopped working, came back up and then stopped working again...

Could it be because I do not have the original set of brains in the car? (DME, Tranny brain, alarm control) Would I need to reprogram these brains with the car's VIN #?

I don't get it though, because it worked for a while like that...

Thanks for your help!

Only a dealer can fugure out something like this, and it is way over my head. I can tell you what the shop manual says.

22 is because there is a fault code in the DME and the fault needs to be fixed.

55 is the vehicles speed signal that comes from the ABS/TC unit and that needs to be fixed.

Actually the other fault code is 56 (instrument cluster activation).

Could you tell me what your manual says about this fault code?

I appreciate all your help.... Thanks!

Sorry, I looked up 55.

56 is listed as instrument cluster activation. The fault is due to the "reduced driver program" whatever that is. There has to be a signal for each of the 5 gears and they test for the signal with an oscilloscope. Then the manual says there is a switch that controls the reversing lights and disables the starter when the transmission is in gear. This switch sends out the signal and if the signal is faulty then the reduced driving program is activated. Sounds like this is why your tip shift lights are flashing. Can't your dealer figure this out?
