FAIL-SAFE

When any of these DTCs, as well as other DTCs relating to electronic throttle control system malfunctions are stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator, and the throttle valve is returned to a 6° throttle angle by the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing, in accordance with the accelerator pedal opening angle, to allow the vehicle to continue at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly.

Fail-safe mode continues until a pass condition is detected, and the ignition switch is then turned off.

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the Clear DTC procedure). Refer to «DTC CHECK / CLEAR»(ref-394619-S02527777542011040800000) .
  4. Turn the ignition switch off and wait for at least 30 seconds.
  5. Turn the ignition switch to ON and turn the Techstream on [A].
  6. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].
  7. With the transmission in 4th gear or more, drive the vehicle at 38 to 75 mph (60 to 120 km/h) for 10 minutes or more [C].
  8. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.
  9. Read the pending DTC [D].
  10. If a pending DTC is output, the system is malfunctioning. HINT: If a pending DTC is not output, perform the following procedure.
  11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  12. Input the DTC: P0136, P0137, P0138, P0156, P0157, or P0158.
  13. 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 UNKNOWN Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU's memory limit WARNING: When performing the confirmation driving pattern, obey all speed limits and traffic laws. HINT: If the judgment result shows ABNORMAL, the system has a malfunction. If the judgment result shows NORMAL, the system is normal. If the judgment result shows INCOMPLETE or UNKNOWN, perform step [C] again.
  14. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  15. Check the judgment result. HINT: If the judgment result shows ABNORMAL, the system has a malfunction. If the judgment result shows NORMAL, the system is normal.
  16. If the test result is INCOMPLETE or UNKNOWN and no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR»(ref-394619-S02527777542011040800000) . HINT: If a permanent DTC is output, the system is malfunctioning. If no permanent DTC is output, the system is normal.
