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 hybrid vehicle control ECU assembly. When the hybrid vehicle control ECU assembly receives this signal, it stores a DTC and performs fail-safe control.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Warning Indicate
P0A0F-204 Engine Failed to Start

Signal indicating abnormality is received from the ECM (abnormal engine output)

Actual engine torque is very low compared to the target torque.

(1 trip detection logic)

SFI system Does not come on

Master Warning Light:

Comes on

P0A0F-205 Engine Failed to Start

Signal indicating abnormality is received from the ECM (engine unable to start)

(1 trip detection logic)

SFI system Does not come on

Master Warning Light:

Comes on

P0A0F-206 Engine Failed to Start

Signal indicating abnormality is received from the ECM (engine component malfunctioning, drop in torque)

SFI system Does not come on

Master Warning Light:

Comes on

P0A0F-524 Engine Failed to Start

Signal indicating abnormality is received from the ECM (abnormal NE signal)

(1 trip detection logic)

SFI system Does not come on

Master Warning Light:

Comes on

P0A0F-525 Engine Failed to Start

Signal indicating abnormality is received from the ECM (abnormal GI signal)

Tech Tips


  • The hybrid vehicle control ECU assembly 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 SFI 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 hybrid vehicle control ECU assembly 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 GTS to the DLC3.

    2. Turn the power switch on (IG).

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

    4. Check for DTCs.


      Powertrain > Engine and ECT > Trouble Codes
    5. Turn the power switch off.
