Volvo All Engines (2013 Emissions) Fault Code: P114113 PID: EMS Buffered Idle Validation Switch Wire – ECM Side

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) Accelerator pedal pressed down more than 50?%

Probable cause
1) Open circuit on signal wire
2) Connector
3) Accelerator pedal

Detailed information
1) The limp home mode does not function

Volvo All Engines (2013 Emissions) Fault Code: P114123 PID: EMS Buffered Idle Validation Switch Wire – ECM Side

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) Accelerator pedal signal does not correspond to actual accelerator pedal position

Observable symptoms
1) The engine does not respond when accelerator pedal is pressed.

Probable cause
1) Accelerator pedal
2) Wiring harness

2) Poor cooling

Probable cause
1) Wiring harness
2) Connector
3) Solenoid valve, engine fan

Volvo All Engines (2013 Emissions) Fault Code: P114411 PID: EMS Starter Relay Highside

Diagnostic operating conditions
1) Ignition key in ON position

Observable symptoms
1) Starter motor does not run

Probable cause
1) Starter motor relay (K65)
2) Wire between Engine Control Module (ECM) and starter motor relay
3) ECM – Engine Control Module

Volvo All Engines (2013 Emissions) Fault Code: P114413 PID: EMS Starter Relay Highside

Diagnostic operating conditions
1) Ignition key in ON position

Observable symptoms
1) Starter motor does not run

Probable cause
1) Starter motor relay (K65)
2) Wiring harness between Engine Control Module and Starter motor relay (K65)
3) Wire between starter relay in dashboard fuse and relay unit and starter motor relay
4) ECM – Engine Control Module

Volvo All Engines (2013 Emissions) Fault Code: P114500 PID: EMS Reductant Level Moderately Low

Aftertreatment Diesel Exhaust Fluid (DEF) Tank, Level Sensor has an indicator lamp and gauge in the instrument cluster. A solid lamp comes on when there is approximately 16% DEF remaining in the tank. A flashing lamp indicates when there is approximately 4% DEF remaining in the tank. A 25% engine derate is possible if the DEF is not refilled above the red line on the gauge at the next engine start up.

Conditions for diagnostic trouble code (DTC):
1) Low fluid level in the tank (Approximately?16%)
2) Low signal voltage from sensor

Probable cause
1) Low fluid level in the tank
2) Wiring harness
3) Aftertreatment diesel exhaust fluid (DEF) tank, Level Sensor, Temperature Sensor
