Good morning,

We have an XF 2.2D chassis in the workshop: SAJBB4BNXGCY19448

The car has 50,000 km and came to the workshop due to the sudden switching on of several warning lights: Abs and Esp, Mil, Tyre Pressure.

In addition, we noticed that the tachometer hands did not work when the voltage (measured by tester) dropped for a few moments to around 12.2 V and then resumed normal operation at 14.5 V, initially leading us to suspect an alternator problem.

I would like to point out that no checks have yet been carried out outside the diagnosis.

Errors detected in diagnosis:

Cannot communicate with engine control unit.

ABS: U0001 High-speed CAN bus

Parking brake: U0001 High-speed CAN bus

Mod. electric selector lever: U0001 High-speed CAN bus

Instrumentation: U0028 CAN Bus A Message absent

Lane Departure Warning: U0001 CAN Bus High Speed; U0002 CAN Bus High Speed

Tyre control: U0001 High-speed CAN bus

We would like your valuable advice to start the search for failure

Thank you
