CHECK FOR INTERMITTENT PROBLEMS

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»(ref-493460-S06003279822012081000000) .
2. Switch the ECM from normal mode to check mode using the Techstream.Refer to «CHECK MODE PROCEDURE»(ref-493460-S33030933402012081000000) .
3. Perform a simulation test.
4. Check and wiggle the harness(es), connector(s) and terminal(s).

REGISTRATION

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 section 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, the one provided with the vehicle and the one stored in the 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. Select the following menu items: 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. Select the following menu items: 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 of on-board diagnostic monitoring tests of specific components/systems that are not continuously monitored. Examples are catalysts and evaporative emissions (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 with the purpose of running 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 diagnostic tester, 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 and turn the Techstream ON. Clear the DTCs.Refer to «DTC CHECK / CLEAR»(ref-493460-S06003279822012081000000) . Run the vehicle in accordance with the applicable drive pattern described in READINESS MONITOR DRIVE PATTERN.Refer to «READINESS MONITOR DRIVE PATTERN»(ref-493460-S13314905742012081000000) . 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 (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.
4. MONITOR RESULT INFORMATION If you use a generic scan tool, multiply the test value by the scaling value listed below.

READINESS MONITOR DRIVE PATTERN

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. The Techstream software must be version 9.0 or newer to view the Readiness Monitor Status. To view the status, select the following menu items: Powertrain / Engine and ECT / Monitor / Current. When the Readiness Monitor status 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 a vehicle's Readiness Monitor status to show Complete before beginning emissions tests. The Readiness Monitor 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 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 may not be detected by normal mode.

Note. The freeze frame data and all the stored DTCs other than permanent DTCs are erased 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 make a note of the freeze frame data and any DTCs other than permanent DTCs.

Scheme 428

1. CHECK MODE PROCEDURE (Using Techstream) Check and ensure the following conditions: Battery positive voltage 11 V or more. Throttle valve fully closed. Transmission in the P or N position. 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. Select the following menu items: Powertrain / Engine and ECT / Utility / Check Mode. Switch the ECM from normal mode to check mode. Make sure the MIL flashes as shown in the illustration. Start the engine. Make sure 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 set, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily.

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 429

1. DATA LIST HINT: By reading the Data List displayed on the Techstream, values can be checked, including those of the switches, sensors, and actuators, without removing any parts. Reading the Data List as the first step of troubleshooting is one method of shortening diagnostic time. NOTE: In the table below, the values listed under Normal Condition are for 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. Select the following menu items: Powertrain / Engine and ECT / Data List. Check the values by referring to the table below.

Stop the engine and turn the ignition switch to ON to turn Control the Cylinder #1 Fuel Cut (to Control the Cylinder #6 Fuel Cut) ON. Start the engine. HINT: *2: When cranking the engine, each cylinder measures the engine speed. In this Active Test, the fuel injection and ignition of all cylinders is cut, and cranking occurs for approximately 10 seconds. Then, each cylinder measures the engine speed. If a cylinder engine speed is higher than the others, that cylinder compression pressure is compared to the others, and whether or not the compression pressure is low can be determined. 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 the 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 #6) 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 HINT: Performing an Evaporative System Check 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. The Evaporative System Check can be performed with the Techstream. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the tester ON. Select the following menu items: Powertrain / Engine and ECT / Utility. Perform the Evaporative System Check by referring to the table below. Tester Display Test Part Control Range Diagnostic Note Evaporative System Check (Automatic Mode) Perform 6 steps in order to operate EVAP key-off monitor automatically - If no DTCs in PENDING CODE after performing this test, system functioning normally 35°C (95°F) or less Refer to EVAP system Evaporative System Check (Manual Mode) Perform 6 steps in order to operate EVAP key-off monitor manually - Used to detect malfunctioning parts 35°C (95°F) or less Refer to EVAP system
