CHECK FOR INTERMITTENT PROBLEMS [08/2013 - ]

HINT

Inspect the 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 the DTCs. Refer to «DTC CHECK / CLEAR [08/2013 - ]»(ref-649257-S06937007322014081400000) .
2. Switch the ECM from normal mode to check mode using the Techstream. Refer to «CHECK MODE PROCEDURE [08/2013 - ]»(ref-649257-S12422950532014081400000) .
3. Perform a simulation test.
4. Check and wiggle the harness(es), connector(s) and terminal(s).

REGISTRATION [08/2013 - ]

Note. The Vehicle Identification Number (VIN) must be input into the 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 service information consists of 2 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 2 VINs, the one provided with the vehicle and stored in the vehicle 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 / 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 / Utility / VIN / VIN Write.

Confirm the following conditions as instructed on the screen. - Ignition switch ON - Engine stopped - Battery voltage is higher than 9 V After confirming, select "Next" and initialize the learned value. HINT: If a message indicating learned value initialization failure is displayed on the screen, confirm the execution conditions, and perform learned value initialization again. After the completion of learned value initialization, confirm the air fuel ratio learned values (A/F Learn Value Idle #1, A/F Learn Value Low #1, A/F Learn Value Mid1 #1, A/F Learn Value Mid2 #1, and A/F Learn Value High #1) in the Data List. Result If 0 is displayed for all the air fuel ratio learned values, initialization has completed correctly. If a value other than 0 is displayed for one of the air fuel ratio learned values, perform initialization again. After initialization, confirm the air fuel ratio learned values. If a value other than 0 is displayed, replace the ECM. *2: Idle Learning Turn the ignition switch off and wait for at least 30 seconds. Start the engine and warm it up until the engine coolant temperature is 80°C (176°F) or higher. HINT: Learning starts when the engine coolant temperature is 80°C (176°F) or higher. After the engine is warmed up, allow it to idle for 5 minutes with the air conditioning and all accessories off. Confirm that the idle speed is within the standard range. Standard Engine Idle Speed 600 to 700 rpm HINT: Be sure to perform this step with all accessories off. Make sure that the shift lever is in P or N. *3: Perform memory reset and idle learning after replacing the throttle body or cleaning deposits from the throttle body. After that, check the idle speed. If the value is out of the specified range, perform the procedure below. WARNING: When performing the confirmation driving pattern, obey all speed limits and traffic laws. HINT: History information for driving and stopping is necessary to update idle learning. Warm up the engine (engine coolant temperature is 80°C (176°F) or higher, air conditioning and all accessories are off) [A]. Drive the vehicle at 10 km/h (6 mph) or more [B]. Idle the engine for 20 seconds or more [C]. Repeat procedure [B] and [C], and check that the idle speed is within the specified range [D]. Standard Engine Idle Speed 600 to 700 rpm HINT: Be sure to perform this step with all accessories off. Make sure that the shift lever is in P or N. If the idle speed is still out of the specified range, repeat procedure [B] and [C] until the idle speed is within the specified range [E]. *4: Drive the vehicle for a short while after replacing the knock control sensor, and check if knocking occurs. If knocking occurs, drive the vehicle until knocking stops.

CHECKING MONITOR STATUS [08/2013 - ]

The purpose of the monitor result (mode 06) is to allow access to the results of 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 Lexus/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 the DTCs. Refer to «DTC CHECK / CLEAR [08/2013 - ]»(ref-649257-S06937007322014081400000) . Operate the vehicle in accordance with the applicable drive pattern described in Readiness Monitor Drive Pattern. Refer to «READINESS MONITOR DRIVE PATTERN [08/2013 - ]»(ref-649257-S24109219232014081400000) . Do not turn the ignition switch off. NOTE: The test results will be lost if the ignition switch is turned off.
2. ACCESS MONITOR RESULT Enter the following menus: Powertrain / Engine / 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 values 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.

READINESS MONITOR DRIVE PATTERN [08/2013 - ]

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 status, enter the following menus: Powertrain / Engine / 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 Monitor to show Complete before beginning emission tests. The Readiness Monitor is 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 the 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).

CHECK MODE PROCEDURE [08/2013 - ]

HINT

Techstream only

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 39

1. CHECK MODE PROCEDURE Check and ensure the following conditions: Battery voltage is 11 V or higher. Throttle valve is fully closed. Shift lever is in P or N. A/C switch is 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 / Utility / Check Mode. Switch the ECM from normal mode to check mode. Check that the MIL flashes as shown in the illustration. Start the engine. Check that the MIL turns off. Simulate the conditions of the malfunction described by the customer. Check DTCs and freeze frame data using the Techstream.

FAIL-SAFE CHART [08/2013 - ]

If any of the following DTCs are stored, 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.

Scheme 40

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 values. Do not depend solely on these reference values when deciding whether a part is faulty or not. 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 / Data List. According to the display on the Techstream, read the Data List.

2. ACTIVE TEST HINT: Using the Techstream to perform 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 / Active Test. According to the display on the Techstream, perform the Active Test.

The test is possible during idle. DTCs related to the VVT system may be stored due to Active Test operation, but this does not indicate a malfunction. Activate the Vacuum Pump Leak detection pump ON/OFF - Activate the VSV for Vent Valve Vent valve ON/OFF - Control the IAC Duty Ratio Control intake air control valve (tumble control valve) duty ratio Between -100 and 100% - Control the Select Cylinder Fuel Cut Select cylinder (cylinder #1 to #4) injection fuel cut #1/#2/#3/#4 ON/OFF Test possible while vehicle stopped and engine idling*1 Control the All Cylinder Fuel Cut All cylinder fuel cut ON/OFF Test possible while vehicle stopped and engine idling*1 Check the Cylinder Compression *2 Check the cylinder compression pressure (measuring engine speed for each cylinder) ON/OFF Fuel injection and ignition stopped in all the cylinders. NOTE: *1: If the display of the Data List item 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 item Catalyst OT MF F/C item is Avail, perform this Active Test as described below. Stop the engine, turn the ignition switch to ON. Enter the Control the Select Cylinder Fuel Cut. Select the cylinder for fuel cut (cylinder #1 to #4) and turn the Active Test ON (press the RIGHT or LEFT button). 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 / 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 stored, 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 / Utility. Perform the System Check by referring to the table below.
