Volvo All Engines (2017 Emissions) Fault Code: P100211 PID: EMS Preheat Relay The preheat Relay controls the preheater from an electric signal from the Engine Control Module (ECM). This function is used to warm up the inlet air during cold conditions. This provides more reliable starting and reduces exhaust emissions during cold starts. Vehicles can be equipped with or without the preheater. Conditions for diagnostic trouble code (DTC):1) Output activated2) Short circuit to battery voltage on A14.EB:25 Observable symptoms1) Intake air heater (IAH) relay never activated2) White smoke at cold start3) Difficult to start in extreme cold Probable cause1) Connector2)...

Volvo All Engines (2017 Emissions) Fault Code: P100400 PID: EMS SCR NOx Catalyst Efficiency Moderately Below Threshold Bank 1 When the aftertreatment selective catalytic reduction (SCR) system operates under normal conditions, the aftertreatment control module (ACM) monitors diesel exhaust fluid (DEF) dosing valve duty cycle and DEF pump control value. When the DEF dosing valve duty cycle increases above allowed threshold and the DEF pump control value decreases below expected threshold, the ACM stops DEF dosing and reports a fault. The fault might be indication of electrical failure or blockage in DEF dosing valve or DEF supply line from the...

Volvo All Engines (2017 Emissions) Fault Code: P100587 PID: EMS Pedal Message The pedal message is used to calculate fuel injection.The J1587 and J1939 serial data lines are used as the standard communication link for on-board vehicle instrumentation, off-board service diagnostics and fleet management.The (VECU) Vehicle Electronic Control Unit is linked to the Engine Control Module (ECM) via these data lines. Conditions for diagnostic trouble code (DTC):1) The accelerator pedal is not connected to the VECU Probable cause1) Accelerator pedal2) Vehicle Control Unit (VECU) Volvo All Engines (2017 Emissions) Fault Code: P100400 PID: EMS SCR NOx Catalyst Efficiency Moderately Below...
