If DTC P1228 is stored, the following symptoms may appear:
Lack of power due to fail-safe operation
When DTC P1228 is stored, check the internal fuel pressure of the common rail by entering the following menus on the GTS: Powertrain / Engine and ECT / Data List / Fuel Press and Target Common Rail Pressure. Under a stable operating condition such as idling, Fuel Press is within +/- 10000 kPa of Target Common Rail Pressure (Reference).
When DTC P1228 is stored, check the Target Pump SCV Current by entering the following menus on the GTS: Powertrain / Engine and ECT / Data List / Target Pump SCV Current. Under stable operating conditions such as idling, Target Pump SCV Current is less than 1530 mA. If the Target Pump SCV Current is 1530 mA or more, the suction control valve (supply pump assembly) or the suction control valve circuit may be malfunctioning.

CAUTION / NOTICE / HINT
When replacing the ECM, perform ECM Initialization and Registration.

Inspect the fuses for circuits related to this system before performing the following procedure.
When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
INSPECT SUPPLY PUMP ASSEMBLY (SUCTION CONTROL VALVE)
Inspect the suction control valve (supply pump assembly).
