A25A-FXS (ENGINE CONTROL): SFI SYSTEM: P319300; Fuel Run Out; 2021 - 2024 MY RAV4 RAV4 HV [08/2020

The ECM receives the low fuel level signal from the combination meter assembly (meter ECU) to detect if the vehicle is running out of fuel.

MONITOR DESCRIPTION

This DTC indicates that the vehicle ran out of fuel. If the ECM receives the low fuel level signal from the combination meter assembly (meter ECU) and the DTC detection conditions of either DTC P319000 or P319100 are met while the ignition switch is ON or the engine is operating, the ECM stores this DTC.

MONITOR STRATEGY

CONFIRMATION DRIVING PATTERN

If the MIL or a master warning light illuminates, immediately end the confirmation driving pattern. When DTCs P319000, P319100 and P319300 are output, the engine may stop. In this case, the HV battery will no longer be chargeable and the distance that the vehicle can be driven will be limited.

Apply the parking brake firmly.
Connect the Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON (READY).
Turn the Techstream on.
Fully depress the accelerator pedal for 10 seconds with the vehicle stopped, the shift lever in P and the brake pedal depressed [A].
NOTICE:

As soon as the engine starts, release the accelerator pedal.
Release the parking brake.
Drive the vehicle at an average of approximately 40 km/h (25 mph) or more until the total engine operation time is 10 minutes or more [B].
CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
- It is not necessary to maintain the vehicle speed at 40 km/h (25 mph) throughout the road test.
- If the engine stops, further depress the accelerator pedal to restart the engine.
Enter the following menus: Powertrain / Engine / Trouble Codes [C].
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P319300.

HINT:

When DTCs P319000, P319100 and P319300 are output, the engine may stop.
In this case, after adding fuel or performing repairs, clear the DTCs. Then turn the ignition switch off to return to the normal condition.
When this DTC is output and the engine is stopped, the HV battery cannot be charged since the vehicle is driven with the motor only. If the vehicle continues to be driven under this condition, the HV battery will become depleted and the ignition switch will not be able to be turned to ON (READY).
