Volvo All Engines (2013 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 voltage
2) Short circuit to ground on A14.EB:30

Diagnostic operating conditions
1) Ignition key in ON position

Observable symptoms
1) The solenoid valve and the brake are activated
2) Engine Shut Down
3) Engine does not start

Probable cause
1) Connector
2) Wiring harness
3) Short circuit to ground on Solenoid valve, compression brake
4) Engine control module (ECM)

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 conditions
1) Ignition key in ON position

Observable symptoms
1) Reduced engine braking since the compression brake cannot be activated
2) Reduced gear selection performance for some automatic transmissions

Probable cause
1) Connector
2) Short circuit in the compression brake solenoid valve
3) Wiring harness
4) Engine control module (ECM)

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) Output not activated

Diagnostic operating conditions
1) Ignition key in ON position

Observable symptoms
1) Reduced engine braking since the compression brake cannot be activated
2) Reduced gear selection performance for some automatic transmissions

Probable cause
1) Open circuit on common supply wire or open circuit on fuse FE9
2) Open circuit in the compression brake solenoid valve
3) Open circuit between Engine control module (ECM) and Solenoid valve, compression brake

Volvo All Engines (2013 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 Spill Valve circuit.

Conditions for diagnostic trouble code (DTC):
1) Injector (INJ) activated
2) Cylinder balancing data too high

Observable symptoms
1) Low Power
2) Uneven operation
3) Abnormal noise

Probable cause
1) Excessive wear or damage to cylinder liners, piston, or piston rings
2) Valves and rocker arms
3) Camshaft
4) VCB control valve sticking or slow to close
5) Injector 3

Volvo All Engines (2013 Emissions) Fault Code: P102400 PID: EMS Cold Start Cylinder 4 Fuel Injector Offset Learning at Max Limit

Fuel Injector operation is controlled by the Engine Control Module (ECM). The ECM provides a common supply voltage to injectors 4,5,6 (Bank 2) 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 Spill Valve circuit.
