A25A-FKS (ENGINE CONTROL): SFI SYSTEM: P064A49; Fuel Pump Control Module Internal Electronic Failure; 2018 MY Camry [03/2017

The fuel pump control ECU has a self-diagnosis function. If there is an internal malfunction, the fuel pump control ECU sends a malfunction signal to the ECM via the FPC drive circuit.

Based on the signal, the ECM judges that there is a malfunction in the fuel pump control ECU and then illuminates the MIL and stores a DTC.

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.
Start the engine and wait 10 seconds or more [A].
Turn the Techstream on.
Enter the following menus: Powertrain / Engine / Trouble Codes [B].
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: P064A49.

Check the DTC judgment result.

Techstream Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions

HINT:

If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system is malfunctioning.
If the judgment result is INCOMPLETE, run the engine at an engine speed of 2000 rpm or more for 10 seconds or more and check the DTC judgment result again.
[A] to [B]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

Powertrain > Engine > Clear DTCs

(a) Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
