Toyota Corolla Cross: Control Module Processor Unexpected Operation (P060694)

Toyota Corolla Cross (2022-2024) Service Manual / Engine & Hybrid System / M20a-fks (engine Control) / Sfi System / Control Module Processor Unexpected Operation (P060694)

DESCRIPTION

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

DTC No.

P060694

Control Module Processor Unexpected Operation

Condition where output of the accelerator opening angle value used for control is more excessive than that of the accelerator opening angle value used for monitoring is continuously detected for 0.5 seconds or more (1 trip detection logic).
  • Accelerator pedal sensor assembly
  • Wire harness or connector
  • ECM

Comes on
  • SAE Code: P0606
  • DTC for Mexico Models: Does not apply

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

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the GTS on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the GTS off.
  6. Turn the ignition switch off.
  7. Disconnect the GTS.
  8. Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
  9. Connect the cable to the negative (-) auxiliary battery terminal.
  10. Connect the GTS to the DLC3.
  11. Start the engine.
  12. Turn the GTS on.
  13. With the vehicle stopped, repeat the accelerator pedal operation (press the accelerator pedal from a state where it is not depressed) several times.
  14. Enter the following menus: Powertrain / Engine / Trouble Codes.
  15. 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.
  16. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  17. Input the DTC: P060694.
  18. Check the DTC judgment result.

    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.

CAUTION / NOTICE / HINT

NOTICE:

  • After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.

  • When disconnecting and reconnecting the auxiliary battery.

    HINT:

    When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.

HINT:

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

1.

CLEAR DTC

(a) Clear the DTCs.

Powertrain > Engine > Clear DTCs

(b) Turn the ignition switch off.

2.

READ OUTPUT DTC (DTC P060694)

(a) Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.

(b) Connect the cable to the negative (-) auxiliary battery terminal.

(c) Start the engine.

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

(e) Read the DTCs.
