CHECK FOR INTERMITTENT PROBLEMS

HINT

Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with the Techstream when the ECM is in check mode. In check mode, the ECM uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detection logic.

1. Clear DTCs. Refer to «DTC CHECK / CLEAR»(ref-427311-S31989667402011101200000) .
2. Switch the ECM from normal mode to check mode using the Techstream. Refer to «CHECK MODE PROCEDURE»(ref-427311-S18345068272011101200000) .
3. Perform a simulation test. Refer to «HOW TO PROCEED WITH TROUBLESHOOTING»(ref-427305-S34248619712011101200000) .
4. Check and wiggle the harness(es), connector(s) and terminal(s). Refer to «ELECTRONIC CIRCUIT INSPECTION PROCEDURE»(ref-427305-S30340386252011101200000) .

REGISTRATION

Note. The Vehicle Identification Number (VIN) must be input into a replacement ECM.

HINT

The VIN is a 17-digit alphanumeric vehicle identification number. The Techstream is required to register the VIN.

1. DESCRIPTION HINT: This registration information consists of two parts: Read VIN and Write VIN. Read VIN: This process allows the VIN stored in the ECM to be read in order to confirm that the two VINs, provided with the vehicle and stored in the vehicle's ECM, are the same. Write VIN: This process allows the VIN to be input into the ECM. If the ECM is changed, or the ECM VIN and vehicle VIN do not match, the VIN can be registered, or overwritten in the ECM by following this procedure.
2. READ VIN Confirm the vehicle VIN. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Read.
3. WRITE VIN Confirm the vehicle VIN. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Write.

CHECKING MONITOR STATUS

The purpose of the monitor result (mode 06) is to allow access to the results for on-board diagnostic monitoring tests of specific components/systems that are not continuously monitored. Examples are catalysts and evaporative emissions (EVAP) systems.

The monitor result allows the OBD II scan tool to display the monitor status, test value, minimum test limit and maximum test limit. These data are displayed after the vehicle has been driven to run the monitor.

When the test value is not between the minimum and maximum test limits, the ECM (PCM) interprets this as a malfunction. If the test value is on the borderline of the test limits, the component is likely to malfunction in the near future.

Perform the following procedures to view the monitor status. Although these procedures refer to the Toyota Techstream, the monitor status can be checked using a generic OBD II scan tool. Refer to your scan tool operator's manual for specific procedural information.

1. PERFORM MONITOR DRIVE PATTERN Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear DTCs. Refer to «DTC CHECK / CLEAR»(ref-427311-S31989667402011101200000) . Operate the vehicle in accordance with the applicable drive pattern described in Readiness Monitor Drive Pattern. Refer to «READINESS MONITOR DRIVE PATTERN»(ref-427311-S30997881282011101200000) . Do not turn the ignition switch off. HINT: The test results will be lost if the ignition switch is turned off.
2. ACCESS MONITOR RESULT Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor / Result. Confirm the monitor status for each component. HINT: The monitor status for each component is displayed in the Result column. Pass: The component is functioning normally. Fail: The component is malfunctioning. Display the test results and test value for a monitor by selecting the icon in the Details column for that monitor.
3. CHECK COMPONENT STATUS Compare the Test Value with the minimum test limit (Min Limit) and maximum test limit (Max Limit). If the test value is between the minimum and maximum test limits, the component is functioning normally. If not, the component is malfunctioning. The test value is usually not near the test limits. If the test value is on the borderline of the test limits, the component is likely to malfunction in the near future. HINT: The monitor result might on rare occasions be Pass even if the Malfunction Indicator Lamp (MIL) is illuminated. This indicates the system malfunctioned on a previous driving cycle. This might be caused by an intermittent problem.

1. PURPOSE OF READINESS TESTS The On-Board Diagnostic (OBD II) system is designed to monitor the performance of emission related components, and indicate any detected abnormalities using DTCs (Diagnostic Trouble Codes). Since various components need to be monitored during different driving conditions, the OBD II system is designed to run separate monitoring programs called Readiness Monitors. To view the monitor status, enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor / Current. When the status of a Readiness Monitor reads Complete, the necessary conditions have been met for running the performance tests for that Readiness Monitor. A generic OBD II scan tool can also be used to view the Readiness Monitor status. HINT: Many state Inspection and Maintenance (I/M) programs require the status of vehicle Readiness Monitors to show Complete before beginning emission tests. The Readiness Monitors will be reset to Incomplete if: The ECM has lost battery power or blown a fuse. DTCs have been cleared. The conditions for running the Readiness Monitor have not been met. If a Readiness Monitor status shows Incomplete, follow the appropriate Readiness Monitor Drive Pattern to change the status to Complete. WARNING: Strictly observe posted speed limits, traffic laws, and road conditions when performing these drive patterns. NOTE: These drive patterns represent the fastest method of satisfying all conditions necessary to achieve complete status for each specific Readiness Monitor. In the event of a drive pattern being interrupted (possibly due to factors such as traffic conditions), the drive pattern can be resumed. In most cases, the Readiness Monitor will still achieve complete status upon completion of the drive pattern. To ensure completion of the Readiness Monitors, avoid sudden changes in vehicle load and speed (driving up and down hills and/or sudden acceleration).
2. CATALYST MONITOR (ACTIVE AIR FUEL RATIO CONTROL TYPE) Preconditions The monitor will not run unless: The MIL is OFF. Drive Pattern (1) Connect the Techstream to the DLC3.

(6) Drive the vehicle at between 40 mph and 70 mph (64 km/h and 113 km/h) for at least 10 minutes. Monitor Status Check the Readiness Monitor status displayed on the Techstream. If the status does not switch to Complete, extend the driving time.
3. EVAP SYSTEM MONITOR (KEY OFF TYPE) Preconditions The monitor will not run unless: The fuel tank is less than 90% full. The altitude is less than 8000 ft. (2438 m). The vehicle is stationary. The engine coolant temperature is between 4.4°C and 35°C (40°F and 95°F). The intake air temperature is between 4.4°C and 35°C (40°F and 95°F). The vehicle was driven in a city area (or on a free-way) for 10 minutes or more. Monitor Conditions Turn the ignition switch off and wait for 5 to 10 hours. HINT: Do not start the engine until checking Readiness Monitor status. If the engine is started, the step described above must be repeated. Monitor Status Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Check the Readiness Monitor status displayed on the Techstream. If the status does not switch to Complete, restart the engine, make sure that the preconditions have been met, and then perform the Monitor Conditions again.
4. AIR FUEL RATIO AND HEATED OXYGEN SENSOR MONITORS (ACTIVE AIR FUEL RATIO CONTROL TYPE) Preconditions The monitor will not run unless: 2 minutes or more have elapsed since the engine was started. The engine coolant temperature is 75°C (167°F) or more. Cumulative driving time at a vehicle speed of 30 mph (48 km/h) or more exceeds 6 minutes. Air fuel ratio feedback control is performed. Drive Pattern for front air fuel ratio sensor and heated oxygen sensor (1) Connect the Techstream to the DLC3. (2) Turn the ignition switch to ON. (3) Turn the Techstream on. (4) Clear DTCs. Refer to «DTC CHECK / CLEAR»(ref-427311-S31989667402011101200000) . (5) Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F). (6) Drive the vehicle at between 37 mph (60 km/h) and 75 mph (120 km/h) for at least 10 minutes. (7) Change the transaxle to 2nd gear. (8) Accelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 10 seconds. (9) Soon after performing step (8) above, release the accelerator pedal for at least 8 seconds without depressing the brake pedal, in order to execute fuel-cut control. (10) Allow the vehicle to decelerate until the vehicle speed declines to less than 6 mph (10 km/h). (11) Repeat steps from (8) through (10) above at least 3 times in one driving cycle. Monitor Status Check the Readiness Monitor status displayed on the Techstream. If the status does not switch to Complete, make sure that the preconditions have been met, and then perform steps from (5) through (11) in Drive Pattern above.

If the status does not switch to Complete, make sure that the preconditions have been met, and repeat steps (5) to (7) described in the Drive Pattern above.

CHECK MODE PROCEDURE

Compared to normal mode, check mode is more sensitive to malfunctions. Therefore, check mode can detect malfunctions that cannot be detected in normal mode.

Note. All the stored DTCs and freeze frame data are cleared if: 1) the ECM is changed from normal mode to check mode or vice versa; or 2) the ignition switch is turned from ON to ACC or OFF while in check mode. Before changing modes, always check and note any DTCs and freeze frame data.

Scheme 66

1. CHECK MODE PROCEDURE Check and ensure the following conditions: Battery voltage 11 V or more. Throttle valve fully closed. Transaxle in P or N (neutral). A/C switch OFF. Turn the ignition switch off. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Utility / Check Mode. Switch the ECM from normal mode to check mode. Make sure that the MIL flashes as shown in the illustration. Start the engine. Make sure that the MIL turns off. Simulate that the conditions of the malfunction described by the customer. Check DTCs and freeze frame data using the Techstream.

FAIL-SAFE CHART

If any of the following DTCs are set, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily or stops fuel injection.

HINT

1. *1: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly. If the accelerator pedal is depressed quickly, the vehicle may speed up and slow down erratically.
2. *2: Misfire related fail-safe operations occur when catalyst overheat malfunctions occur.

1. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time. NOTE: In the table below, the values listed under Normal Condition are reference only. Do not depend solely on these values when determining whether or not a part is faulty. Warm up the engine. Turn the ignition switch off. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Data List. According to the display on the Techstream, read the Data List.

2. ACTIVE TEST HINT: Using the Techstream to perform the Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests. Warm up the engine. Turn the ignition switch off. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Active Test. According to the display on the Techstream, perform the Active Test.

At the time this Active Test item is entered = 100% Below 100% = Fuel injection volume is decreased Higher than 100% = Fuel injection volume is increased To conduct the test, enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Imbalance Cylinder / Data List / A/F Sensor Determination (worst value) and Engine Speed Fluctuation Avg (worst value). Refer to «DTC P219A: Bank 1 Air-Fuel Ratio Imbalance»(ref-427472-S15033385442011101200000) . NOTE: *1: If the display of the Data List Catalyst OT MF F/C item is Not Avl, perform this Active Test with the vehicle stopped and the engine idling. If the display of the Data List Catalyst OT MF F/C item is Avail, perform this Active Test as described below. Stop the engine and turn the ignition switch to ON to turn Control the Cylinder #1 Fuel Cut (to #4 Fuel Cut) ON. Start the engine. HINT: *2: When cranking the engine, each cylinder measures the engine speed. In this Active Test, the fuel and ignition of all cylinders is cut. The engine must then be cranked for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is more than the other cylinders, it can be determined that the compression pressure of that cylinder is lower than the other cylinders. Warm up the engine. Turn the ignition switch off. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression. HINT: To display the entire Data List, press the pull down menu button next to Primary. Then select Compression. Push the snapshot button to turn the snapshot function on. HINT: Using the snapshot function, data can be recorded during the Active Test. While the engine is not running, press the RIGHT or LEFT button to change Check the Cylinder Compression to ON. HINT: After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement enters standby mode. Crank the engine for about 10 seconds. HINT: Continue to crank the engine until the values change from the default value (51199 RPM). Monitor the engine speed (Engine Speed of Cyl #1 to #4) displayed on the Techstream. HINT: At first, the Techstream displays extremely high cylinder engine speed values. After approximately 10 seconds of engine cranking, each cylinder engine speed measurement will change to the actual engine speed. NOTE: Do not crank the engine continuously for 20 seconds or more. If it is necessary to crank the engine again after Check the Cylinder Compression has been changed to ON and the engine has been cranked once, press Exit to return to the Active Test menu screen. Then change Check the Cylinder Compression to ON and crank the engine. Use a fully-charged battery. Stop cranking the engine, and then change "Check the Cylinder Compression" to OFF after the engine stops. NOTE: If the Active Test is changed to OFF while the engine is being cranked, the engine will start. Push the snapshot button to turn the snapshot function off. Select "Stored Data" on the Techstream screen, select the recorded data and display the data as a graph. HINT: If the data is not displayed as a graph, the change of the values cannot be observed. Check the change in engine speed values. HINT: As the data values of the Active Test return to their default values when cranking is stopped, the engine speed value of each cylinder cannot be observed. Therefore, it is necessary to use the data recorded with the snapshot function to check the engine speed values recorded during cranking.
3. SYSTEM CHECK HINT: Performing a System Check in the Utility menu enables the system, which consists of multiple actuators, to be operated without removing any parts. In addition, it can show whether or not any DTCs are set, and can detect potential malfunctions in the system. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Utility. Perform the System Check by referring to the table below.
