M20A-FKS (ENGINE CONTROL): SFI SYSTEM: P060694; Control Module Processor Unexpected Operation; 2023 MY Corolla Corolla Hatchback [11/2022

The ECM calculates and compares the accelerator pedal opening angle value used for control and the value used for monitoring.

MONITOR DESCRIPTION

The ECM calculates the accelerator pedal opening angle value used for control and the value used for monitoring. If the ECM determines there is an excessive output while the engine is running, a DTC is stored and the MIL is illuminated.

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the GTS off.
Turn the ignition switch off.
Disconnect the GTS.
Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
Connect the cable to the negative (-) battery terminal.
Connect the GTS to the DLC3.
Start the engine [A].
Turn the GTS on.
With the vehicle stopped, repeat the accelerator pedal operation (press the accelerator pedal from a state where it is not depressed) several times [B].
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: P060694.

Check the DTC judgment result.

GTS 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, perform steps [A] through [C] again.
[A] to [C]: 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.

Read Freeze Frame Data using the GTS. 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) Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.

(d) With the vehicle stopped, repeat the accelerator pedal operation (press the accelerator pedal from a state where it is not depressed) several times.
