1. DESCRIPTION When troubleshooting OBD II (On-Board Diagnostics) vehicles, Techstream (complying with SAE J1987) must be connected to the DLC3 (Data Link Connector 3) of the vehicle. Various data in the vehicle's ECM (Engine Control Module) can be then read. OBD ll regulations require that the vehicle's on-board computer illuminates the MIL (Malfunction Indicator Lamp) on the instrument panel when the computer detects a malfunction in: The emission control systems components. The power train control components (which affect vehicle emissions). The computer itself. In addition, the applicable DTCs (Diagnostic Trouble Codes) prescribed by SAE J2012 are recorded on 3 consecutive trips, the MIL turns off automatically but the DTCs remain recorded in the ECM memory. To check the DTCs, connect Techstream to the DLC3. The tester displays DTCs, freeze frame data, and a variety of the engine data. The DTCs and freeze frame data can be erased with the tester. In order to enhance OBD function on vehicles and develop the Off-Board diagnosis system, CAN communication is introduced in this system (CAN: Controller Area Network). It minimizes a gap between technician skills and vehicle technology. CAN is a network, which uses a pair of data transmission lines, spanning multiple computers and sensors. It allows a high speed communication between the systems and simplification of the wire harness connection.
2. NORMAL MODE AND CHECK MODE The diagnosis system operates in normal mode during normal vehicle use. In normal mode, 2 trip detection logic is used to ensure accurate detection of malfunctions. Check mode is also available as an option for technicians. In check mode, 1 trip detection logic is used for simulating malfunction symptoms and increasing the system's ability to detect malfunctions, including intermittent problems (Techstream only).
3. 2 TRIP DETECTION LOGIC When a malfunction is first detected, the malfunction is temporarily stored in the ECM memory (1st trip). If the same malfunction is detected during the next subsequent drive cycle, the MIL is illuminate (2nd trip).
4. FREEZE FRAME DATA The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
5. DLC3 (Data link Connector 3) The vehicle's ECM uses the ISO 15765-4 for communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format. Symbols Terminal No. Names Reference terminal Results Condition SIL 7 Bus "+" line 5 - Signal ground Pulse generation During transmission CG 4 Chassis ground Body ground 1 ohms or less Always SG 5 Signal ground Body ground 1 ohms or less Always BAT 16 Battery ground Body ground 9 to 14 V Always CANH 6 CAN "High" line CANL 54 to 69 ohms Engine switch off CANH 6 CAN "High" line Battery positive 1 Mohms or higher Engine switch off CANH 6 CAN "High" line CG 1 kohms or higher Engine switch off CANL 14 CAN "Low" line Battery positive 1 Mohms or higher Engine switch off CANL 14 CAN "Low" line CG 1 kohms or higher Engine switch off HINT: The DLC3 is the interface prepared for reading various data from the vehicle's ECM. After connecting the cable of Techstream, turn the engine switch on (IG) and turn the tester on. If a communication failure message is displayed on the tester screen (on the tester: UNABLE TO CONNECT TO VEHICLE), a problem exists in either the vehicle or tester. In order to identify the location of the problem, connect the tester to another vehicle. If communication is normal: Inspect the DLC3 on the original vehicle. If communication is still not possible: The problem is probably in the tester itself. Consult the Service Department listed in the instruction manual.
6. BATTERY VOLTAGE Standard Voltage 11 to 14 V If voltage is below 11 V, replace or recharge the battery before proceeding.
7. MIL (Malfunction Indicator Lamp) The MIL is illuminated when the engine switch is first turned on (the engine is not running). The MIL should turn OFF when the engine is started. If the MIL remains illuminated, the diagnosis system has detected a malfunction or abnormality in the system. HINT: If the MIL is not illuminated when the engine switch is first turned on, check the MIL circuit. Refer to «MIL Circuit»(ref-387361-S12226687202011022400000).
8. ALL READINESS HINT: With All Readiness you can check whether or not the DTC judgment has been completed by using Techstream. You should check All Readiness after simulating malfunction symptoms or for validation after finishing repairs. Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn Techstream ON. Clear the DTCs. Perform the DTC judgment driving pattern to run the DTC judgment. Select the following menu items: Powertrain / Engine and ECT / Utility / All Readiness. Input the DTCs to be confirmed. Check the DTC judgment result. TECHSTREAM: Tester Display Description NORMAL DTC judgment completed System normal ABNORMAL DTC judgment completed System normal INCOMPLETE DTC judgment not completed You should perform driving pattern after confirming DTC enabling conditions UNKNOWN Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU's memory limit

DTC CHECK / CLEAR

Note. When the diagnosis system is changed from the normal mode to check mode or vice versa, all DTCs and freeze frame data recorded in normal mode are erased. Before changing modes, always check and make a note of DTCs and freeze frame data.

HINT

1. DTCs which are stored in the ECM can be displayed on Techstream. Techstream can display the current and pending DTCs.
2. Same DTCs are not set if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.

1. CHECK DTC (Using Techstream) Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn the tester on. Enter the following menu items: Powertrain / Engine and ECT / Trouble Codes. Check the DTC(s) and freeze frame data, and then write them down. Check the details of the DTC(s). Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-387359-S23628788162011022400000).
2. CLEAR DTC (Using Techstream) Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn the tester on. Enter the following menu items: Powertrain / Engine and ECT / Trouble Codes. Erase the DTCs.
3. CLEAR DTC (Without using Techstream) Perform either one of the following operations: Disconnect the negative battery cable for more than 1 minute. Remove the EFI and ETCS fuses from the engine room J/B and R/B No. 2 located inside the engine compartment for more than 1 minute.

Scheme 22

1. DESCRIPTION The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction. HINT: If it is impossible to replicate the problem even though a DTC is detected, confirm the freeze frame data. The ECM records engine conditions in the from of freeze frame data every 0.5 seconds. Using Techstream, five separate sets of freeze frame data, including the data values at the time when the DTC was set, can be checked. 3 data set before the DTC was set. 1 data set when the DTC was set. 1 data set after the DTC was set. These data sets can be used to simulate the condition of the vehicle around the time of the occurrence of the malfunction. The data may assist in identifying of the cause of the malfunction, and in judging whether it was temporary or not.

If the display of the Data List's Catalyst OT MF F/C item is Avail, perform this Active Test as described below. Stop the engine and turn the engine switch on (IG) to turn Control the Cylinder #1 Fuel Cut (to #6 Fuel Cut) ON. Start the engine. HINT: *2: When performing the Active Test item "Check the Cylinder Compression" and then cranking the engine, the ECM stops the fuel injection and ignition, and measures the engine speed for each cylinder. If one cylinder's speed is higher than the others, that cylinder's compression pressure can be concluded to be lower than the others. Warm up the engine. Turn the engine switch off. Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn the tester ON. Select the following menu items: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression. Select the following monitor items: Compression / Engine Speed of Cyl #1 to #6, Av Engine Speed of All Cyl Press the RIGHT or LEFT button to change the Check the Cylinder Compression to ON. HINT: Fuel injection and ignition for all cylinders are prohibited at this time, and each cylinder's engine speed measurement will enter standby mode. Crank the engine until the monitor item values "Engine speed of Cyl #1 to #6" and "Av Engine Speed of All Cyl" change. Monitor the engine speed (Engine Speed of Cyl #1 to #6, Av Engine Speed of All Cyl) displayed on the tester. HINT: The tester displays the values to be extremely high before cranking the engine. Each cylinder's engine speed is measured while cranking the engine and then the tester displays the actual engine speed values. NOTE: The Active Test item "Check the Cylinder Compression" will automatically turn off 255 seconds after the Active Test is turned on. When the "Check the Cylinder Compression" is OFF and the engine is cranked, the engine will start. If the "Check the Cylinder Compression" test needs to be performed again after each cylinder's engine speed measurement has been performed once, press EXIT to return to the Active Test menu screen. Then perform the Check the Cylinder Compression test again. Use a fully-charged battery.
3. SYSTEM CHECK HINT: Performing a 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 System Check can be performed with Techstream. Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn the tester on. Enter the following menus: Powertrain / Engine and ECT / Utility. Perform the System Check by referring to the below. Tester Display Test Part Control Range Diagnostic Note Evaporative System Check (Automatic Mode) Perform 4 steps in order to operate EVAP key-off monitor automatically 35°C (95°F) or less If no DTCs in PENDING CODE after performing this test, system functioning normally Refer to EVAP system.
