FAIL-SAFE

When any of these DTCs or other DTCs relating to Electronic Throttle Control System (ETCS) 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 6.0° 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 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.

  6. Using the Techstream, switch the ECM from normal mode to check mode. Refer to «CHECK MODE PROCEDURE»(ref-472430-S10029917792012051500000) .
  7. Read the misfire counts of each cylinder, Cylinder #1 Misfire Count to Cylinder #4 Misfire Count, with the engine idling. If any misfire count is displayed, skip the following confirmation driving pattern.
  8. Drive the vehicle so that the vehicle conditions displayed in Misfire RPM and Misfire Load of the Data List are the same as the freeze frame data. Perform this step several times. HINT: In order to store misfire DTCs, it is necessary to operate the vehicle for the period of time shown in the table below, confirm the Misfire RPM and Misfire Load in the Data List. Engine speed Duration Idling 8.0 minutes or more 1000 4.5 minutes or more 2000 2.5 minutes or more 3000 1.5 minutes or more
  9. Check whether misfires have occurred by checking DTCs and freeze frame data. HINT: Do not turn the ignition switch off until the output DTC(s) and freeze frame data have been recorded. When the ECM returns to normal mode (default), the stored DTC(s), freeze frame data and other data are cleared.
  10. Record the DTC(s), freeze frame data and misfire counts.
  11. Turn the ignition switch off and wait for at least 30 seconds.
  12. Clear DTCs (even if no DTCs are stored, perform the Clear DTC procedure).

If the judgment result shows ABNORMAL, the system has a malfunction. If the judgment result shows INCOMPLETE or N/A, idle the engine for 5 minutes and check the DTC judgment result again.
  12. If no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR»(ref-472430-S28797856862012051500000) . HINT: If a permanent DTC is output, the system is malfunctioning. If no permanent DTC is output, the system is normal.
