Default Error code and T4

Trying to assist an owner miles away on the island of Gotland who has been to a local T4 equipped garage and told that he needs to replace his ECM.

He has now got back to me saying the error code is: P1647 CAN-buss kombiinstrument felaktig (CAN-bus IPK faulty).

Not much information using the search, so does he need a replacement IPK or EMU or is it a CAN-bus error possibly from water ingress?

Another owner tells me his garage confirmed he had a 88 deg thermostat by using a T4. I'm guessing a T4 can read the coolant temperature, any hints to where I'll find it appreciated.

Regards

Is it a diesel? That message comes up on diesel ECU'S that although still working the can-bus controller is likely to pack in
Depends where the fault was stored. If the can bus controller is still working then T4 will see the coolant temperature.

Sorry forgot to add car specs: a V6 2000 poverty spec manual. Diesels are just about extinct here. I believe the fault was stored in the ECM.

How do I go about checking the coolant temperature? Only just finding my way around the T4.

Your assistance appreciated

Ah that clears that up
You can view the temperature in live data in the engine management screen on T4
