Additional coolant pump 997 turbo 2007

Dear all

I do have an (electrical??) issue with the "Additional Coolant Pump"

During read out an error is reported. Up to now I do no not know if the pump is defective or the control unit.

To change the pump (of which I do not now if it is defective) you need to lower the engine, and remove:

fuel filter,

secondary air pump,

intake distributor side 1-3,

shut off valve.

A major task which I trie to avoid.

An other approach is to ativate the pump the by appying 12Volt at the DME control unit.

therefore I need the electrical diagrams of the 997 turbo year 2007/2008.

I already tried at the official Porsche side with the PIWIS system but I did not succed.

Is there any one having these diagrams available.

Would be a great help!!

Regards

Hans, The Netherlands
