Engine Control System (Diagnostics & Circuit Tests): Diagnosis Scion tC II рестайлинг

INSPECTION PROCEDURE

Note. Inspect the fuses for circuits related to this system before performing the following inspection procedure. The Techstream is required to conduct the following diagnostic troubleshooting procedure.

HINT

1. Using the Techstream monitor results enables the EVAP (Evaporative Emission) system to be confirmed.
2. Read freeze frame data using the Techstream. 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.

Scheme 112

1. CONFIRM DTC Turn the ignition switch off and wait for 10 seconds. Turn the ignition switch to ON. Turn the ignition switch off and wait for 10 seconds. Connect the Techstream to the DLC3. Turn the ignition switch to ON and turn the Techstream on. Enter the following menus: Powertrain / Engine / Trouble Codes. Confirm DTCs and freeze frame data. If any EVAP system DTCs are stored, the malfunctioning area can be determined using the table below. NOTE: If the reference pressure difference between the first and second checks is more than the specification, all the DTCs relating to the reference pressure (P043E, P043F, P2401, P2402 and P2419) are stored. NEXT: Go to next step
2. PERFORM EVAP SYSTEM CHECK (AUTOMATIC MODE) 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 temperature below 35°C (95°F). Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear DTCs. Refer to «DTC CHECK / CLEAR [05/2013 - 01/2014]»(ref-615120-S02653872462014050900000) . Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode. After the EVAP SYSTEM CHECK is completed, check for pending DTCs by entering the following menus: Powertrain / Engine / Trouble Codes. HINT: If no pending DTCs are displayed, perform the Confirmation Driving Pattern. After this confirmation, check for pending DTCs. If no DTCs are displayed, the EVAP system is normal. NEXT: Go to next step
3. PERFORM EVAP SYSTEM CHECK (MANUAL MODE) NOTE: In the Evaporative System Check (Manual Mode), the series of 6 Evaporative System Check steps are performed manually using the Techstream. 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 temperature below 35°C (95°F). Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear DTCs.

Inspection Method

Example

Drive at 10 km/h (6.25 mph), depress the accelerator pedal by 1/2 to 3/4 and keep it in that position. Under these conditions, if the engine speed decreases to 1000 rpm when the brake pedal is depressed, the brake override system has been activated.

HINT

1. Under normal conditions, the Accelerator Position value changes in response to the Accel Sens. No. 1 Volt % value. For more information on the numerical values, refer to the Data List. Refer to «DATA LIST / ACTIVE TEST [05/2013 - 01/2014]»(ref-615234-S35938653532014050900000) .
2. If the Accelerator Position and Accel Sens.No. 1 Volt% values in the Data List diverge and the Accelerator Position value in the Data List is fixed even though Accel Sens.No. 1 Volt% is changing, check that this control is activated (use the GTS data saving function to record data while driving the vehicle, and then confirm it after driving is completed).

Note. The brake override system restricts driving torque if the brake pedal is depressed when driving with the accelerator pedal depressed. If a customer reports experiencing loss of torque after the accelerator and brake pedals have both been intentionally depressed, explain to the customer that this is not a malfunction, and that the customer should avoid depressing both the accelerator and brake pedals at the same time. Example: While operating the accelerator pedal, the customer uses their left foot to operate the brake pedal.
