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 6.5° 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.

11. CHECK WHETHER DTC OUTPUT RECURS (DTC P0420) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear the DTCs. Refer to «DTC CHECK / CLEAR»(ref-554492-S07547393792013052000000) . Turn the ignition switch off and wait for at least 30 seconds. Turn the ignition switch to ON. Turn the Techstream on. Start the engine. Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern. Read DTCs. RESULT Result Proceed to DTC P0420 is output A DTC is not output (No pending DTCs output) B B --> END A: Go to next step
12. REPLACE FRONT EXHAUST PIPE ASSEMBLY (TWC: FRONT AND REAR CATALYST) HINT: Confirm the replacement parts, referring to the illustration in the Catalyst Location. Replace the front exhaust pipe assembly (TWC: front and rear catalyst). Refer to «COMPONENTS»(ref-554504-S07261416342013052000000) . NEXT --> END
13. GO TO DTC CHART. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-554492-S12437688692013052000000)

"Saturated" indicates that the EVAP pressure change is below 0.286 kPa(gauge) [2.14 mmHg(gauge)] in 60 seconds.

Refer to Checking Monitor Status. Refer to CHECKING MONITOR STATUS .

Note. The Evaporative System Check (Automatic Mode) consists of 6 steps performed automatically by the Techstream. It takes a maximum of approximately 24 minutes. Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable. Do not run the engine during this operation. When the temperature of the fuel is 35°C (95°F) or higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature below 35°C (95°F).

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).
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.
6. Enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Automatic Mode.
7. After the "Evaporative System Check" is completed, check for All Readiness by entering the following menus: Powertrain / Engine and ECT / Utility / All readiness.
8. Input the DTC: P043E, P043F, P2401, P2402 or P2419.
9. 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 N/A Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit HINT: If the judgment result shows NORMAL, the system is normal. If the judgment result shows ABNORMAL, the system has a malfunction.
10. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR»(ref-554492-S07547393792013052000000) . HINT: If a permanent DTC is output, the system is malfunctioning. If no permanent DTC is output, the system is normal.
