Volvo All Engines (2017 Emissions) Fault Code: U032300 PID: EMS Software Incompatibility With Instrument Panel Control Module

The Idle Validation Switch is open at the idle position and transmits no voltage to the (VECU) Vehicle Electronic Control Unit. At approximately 1-13% pedal position the Idle Validation Switch closes and completes the circuit to the (VECU) Vehicle Electronic Control Unit.
The (VECU) Vehicle Electronic Control Unit then sends a voltage signal to the Engine Control Module (ECM) indicating accelerator pedal position. If both communication links (J1939, J1587) are faulty the pedal demand functionality enters limp-home. During limp-home the (IVS) Idle Validation Switch is used for ramping requested torque.

Conditions for diagnostic trouble code (DTC):
1) Incorrect vehicle identification number (VIN) from Instrument Cluster (IC)

Probable cause
1) The electronic control unit (ECU) has a software fault or the wrong software version
