HYBRID CONTROL SYSTEM, Diagnostic DTC:P0A0F-204, P0A0F-205, P0A0F-206, P0A0F-524, P0A0F-525

DTC Code DTC Name
P0A0F-204 Engine Failed to Start
P0A0F-205 Engine Failed to Start
P0A0F-206 Engine Failed to Start
P0A0F-524 Engine Failed to Start
P0A0F-525 Engine Failed to Start

DESCRIPTION

If an engine malfunction occurs, an engine malfunction signal is sent from the ECM to the power management control ECU (HV CPU) . When the power management control ECU (HV CPU) receives this signal, it sets a DTC and performs fail-safe control.

DTC No. INF Code DTC Detection Condition Trouble Area
P0A0F 204 Signal indicating abnormality input from the ECM (abnormal engine output) SFI system
205 Signal indicating abnormality input from the ECM (engine is unable to start)
206 Signal indicating abnormality input from the ECM (engine component malfunction)
524 Signal indicating abnormality input from the ECM (NE signal error)
525 Signal indicating abnormality input from the ECM (GI signal error)

Tech Tips


  • The power management control ECU (HV CPU) stores DTC P0A0F-204, 205, 206, 524 or 525 when it receives a signal from the ECM indicating abnormal engine power, engine starting malfunction, engine performance deterioration (running out of fuel), crank angle sensor circuit DTCs or cam position sensor circuit DTCs.

  • If the engine cannot start, the vehicle is driven using EV drive mode. However, if the vehicle is continuously driven using only EV drive mode, the HV battery will be discharged and the vehicle will not be able to be driven.

  • If any of these DTCs are output, it is required to repair the EFI system in accordance with the DTC or to add a sufficient amount of fuel.

CAUTION / NOTICE / HINT

Tech Tips


  • When SFI system related DTCs are output, the power management control ECU stores DTCs P0A0F-204, 205, 206, 524 or 525.

  • If SFI system related DTCs are stored, the MIL will illuminate.

PROCEDURE


  1. CHECK DTC OUTPUT (ENGINE AND ECT)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Engine and ECT / DTC.

    4. Check if DTCs are output.

      Result
      Result Proceed to
      SFI system DTCs are output (for 2ZR-FXE (w/ EGR System)). A
      SFI system DTCs are output (for 2ZR-FXE (w/o EGR System)). B
      SFI system DTCs are output (for 5ZR-FXE). C

    5. Turn the power switch off.
