CHECK FOR INTERMITTENT PROBLEMS

HINT

Inspect the vehicle 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-493432-S34411502992012081000000) .
2. Switch the ECM from normal mode to check mode using the Techstream.Refer to «CHECK MODE PROCEDURE»(ref-493432-S20362634172012081000000) .
3. Perform a simulation test.Refer to «HOW TO PROCEED WITH TROUBLESHOOTING»(ref-493289-S22966865862012081000000) .
4. Check and wiggle the harness(es), connector(s) and terminal(s).Refer to «HOW TO PROCEED WITH TROUBLESHOOTING»(ref-493289-S22966865862012081000000) .

REGISTRATION

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

HINT

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

1. DESCRIPTION (Using the Techstream) HINT: This registration section consists of two parts: Read VIN and Write VIN. Read VIN: Explains the VIN reading process in a flowchart. 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 ECM, are the same. Write VIN: Explains the VIN writing process in a flowchart. This process allows the VIN to be input into the ECM. If the ECM is replaced, 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 the catalyst and evaporative emission (EVAP) system.

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 test limit and maximum test limit, the ECM (PCM) interprets this as a malfunction. When the component is not malfunctioning, if the difference of the test value and test limit is very small, the component will malfunction in the near future.

Perform the following procedure to view the monitor status. Although this procedure references the Lexus/Toyota diagnostic tester, it can be checked using a generic OBD II scan tool. Refer to your scan tool operator's manual for specific procedures.

1. PERFORM MONITOR DRIVE PATTERN Connect the Techstream to the DLC3. Turn the ignition switch to ON and the Techstream on. Clear DTCs.Refer to «DTC CHECK / CLEAR»(ref-493432-S34411502992012081000000) . Drive the vehicle in accordance with the applicable drive pattern described in Readiness Monitor Drive Pattern.Refer to «READINESS MONITOR DRIVE PATTERN»(ref-493432-S35388683572012081000000) . 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 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 for a monitor by selecting the icon in the Details column for that monitor. Display the test value for an item listed under Test Results by selecting the icon in the Details column for that item.
3. CHECK COMPONENT STATUS Compare the test value with the minimum test limit and maximum test limit. If the test value is between the minimum test limit and maximum test limit, the component is functioning normally. If not, the component is malfunctioning. The test value is usually significantly more or less than the test limit. If the test value is on the borderline of the test limit, the component will 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 with 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 Readiness Monitor status displays 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 vehicle Readiness Monitor status 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

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 37

1. CHECK MODE PROCEDURE Check and ensure the following conditions: Battery voltage is 11 V or higher. Throttle valve is fully closed. Transmission is in the P or N (neutral) position. 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 and ECT / 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

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.

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 and ECT / 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 and ECT / Active Test. According to the display on the Techstream, perform the Active Test. Tester Display Test Part Control Range Diagnostic Note Control the Injection Volume Change injection volume -12.5 to 24.8% All the injectors are tested at the same time. Perform the test at less than 3000 rpm. The injection volume can be changed in 1% graduations within the control range. Control the Injection Volume for A/F Sensor Change injection volume -12.5, 0 or +12.5% Perform the test at less than 3000 rpm. Control the Injection Volume for A/F Sensor enables the checking and graphing of the A/F (Air Fuel Ratio) sensor and Heated Oxygen (HO2) sensor voltage outputs. To conduct the test, enter the following menus: Active Test / Control the Injection Volume for A/F Sensor / Data List / A/F Control System / AFS Voltage B1S1 and O2S B1S2.

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. Control the VVT System (Bank1) Turn on and off OCV (Camshaft Timing Oil Control Valve) ON/OFF The engine stalls or idles roughly when the OCV is turned ON. The engine is running and idles normally when the OCV is OFF. 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. Control the VVT Exhaust Linear (Bank 1) Control VVT (Bank 1) Between -128 and 127% The engine stalls or idles roughly when the VVT actuator is operated at 100%. 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 duty ratio Between -100 and 100% - Control the Select Cylinder Fuel Cut Selected cylinder (cylinder #1 to #4) injector fuel cut #1/#2/#3/#4 ON/OFF The test is possible while the vehicle is stopped and the engine is idling.*1 Control the All Cylinders Fuel Cut All cylinder fuel cut ON/OFF The test is possible while the vehicle is stopped and the engine is idling.*1 Check the Cylinder Compression*2 Check the cylinder compression pressure (measuring engine speed for each cylinder) ON/OFF Fuel injection and ignition stop in all the cylinders. NOTE: *1: If the display of the Catalyst OT MF F/C item of the Data List is Not Avl, perform this Active Test with the vehicle stopped and the engine idling. If the display of the Catalyst OT MF F/C item of the Data List 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 Control the Cylinder #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 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). 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. 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. 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 (Only for Techstream) 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 and ECT / Utility. Perform the System Check by referring to the table below.
