Volvo All Engines (2017 Emissions) Fault Code: P102111 PID: EMS Volvo Compression Brake (VCB) Control Circuit The Engine Compression Brake Relay is supplied battery voltage through a fuse when the Engine Control Module (ECM) Relay is energized.The Engine Control Module (ECM) grounds and completes the circuit for the Engine Compression Brake Relay to activate the compression brake. Conditions for diagnostic trouble code (DTC):1) The voltage is less than 30% Supply voltage2) Short circuit to ground on A14.EB:30 Diagnostic operating conditions1) Ignition key in ON position Observable symptoms1) The solenoid valve and the brake are activated2) Engine Shut Down3) Engine does...

Volvo All Engines (2017 Emissions) Fault Code: P102112 PID: EMS Volvo Compression Brake (VCB) Control Circuit The Engine Compression Brake Relay is supplied battery voltage through a fuse when the Engine Control Module (ECM) Relay is energized.The Engine Control Module (ECM) grounds and completes the circuit for the Engine Compression Brake Relay to activate the compression brake. Conditions for diagnostic trouble code (DTC):1) Short circuit to battery voltage on A14.EB:30 Diagnostic operating conditions1) Ignition key in ON position Observable symptoms1) Reduced engine braking since the compression brake cannot be activated2) Reduced gear selection performance for some automatic transmissions Probable cause1)...

Conditions for diagnostic trouble code (DTC):1) Output not activated Diagnostic operating conditions1) Ignition key in ON position Observable symptoms1) Reduced engine braking since the compression brake cannot be activated2) Reduced gear selection performance for some automatic transmissions Probable cause1) Open circuit on common...

Volvo All Engines (2017 Emissions) Fault Code: P102300 PID: EMS Cold Start Cylinder 3 Fuel Injector Offset Learning at Min Limit Fuel Injector operation is controlled by the Engine Control Module (ECM). The ECM provides a common supply voltage to injectors 1,2,3 (Bank 1) and there are individual output transistor drivers inside the ECM to control each individual injector’s ground circuits. There are two solenoid circuits within the injector; a Needle Control Valve and a Spill Valve. Although they are separate circuits, the same fault code is used to identify a fault in the Needle Control Valve circuit and/or the...
