Volvo All Engines (2013 Emissions) Fault Code: U042600 PID: EMS Invalid Data Received From Vehicle Immobilizer Control Module

The immobilizer function is a part of a system that prevents the engine from starting if the correct security code is not used. After the ignition is switched on, a security code is broadcast from the ECM to the immobilizer control unit or the instrument cluster (US market). Engine start is permitted if a correct response message is received within a certain number of tries and within a certain time from the immobilizer control unit/instrument cluster

Observable symptoms
Engine cannot be started

Probable cause

Data link failure
1) Open circuit
2) Short circuit between wires
3) Control units, voltage supply

Software error:
1) Engine control module (ECM)
2) Instrument cluster

Volvo All Engines (2013 Emissions) Fault Code: U117300 PID: EMS Lost Communication with IPC Control Module on High Speed CAN Communication Bus

Conditions for diagnostic trouble code (DTC):
1) Human-Machine Interface I/O Module datalink circuit

Probable cause
1) The electronic control unit (ECU) has a software fault or the wrong software version
2) Control unit has no supply voltage
3) Connector
4) Data link

Volvo All Engines (2013 Emissions) Fault Code: U300001 PID: EMS Electronic Control Unit

Battery voltage is monitored by the circuits within the Engine Control Module (ECM).

Conditions for diagnostic trouble code (DTC):
1) The voltage is more than 15V

Probable cause
1) Battery charger connected
2) Alternator
3) Damaged component, Engine Control Module
