1. DESCRIPTION When troubleshooting OBD II (On-Board Diagnostics) vehicles, a 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 II regulations require that the vehicle's on-board computer illuminate the MIL (Malfunction Indicator Lamp) on the instrument panel when the computer detects a malfunction in: The emission control system components. The power train control components (which affect vehicle emissions). The computer itself. In addition, if the applicable DTCs (Diagnostic Trouble Codes) prescribed by SAE J2012 are not recorded on 3 consecutive trips, the MIL turns off automatically but the DTCs remain recorded in the ECM memory. To check DTCs, connect the Techstream to the DLC3. The Techstream displays DTCs, freeze frame data, and a variety of the engine data. The DTCs and freeze frame data can be erased with the Techstream. Refer to «DTC CHECK / CLEAR»(ref-394513-S17742279252011040800000). 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 the 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 high speed communication between the systems and simplifies 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). Refer to «CHECK MODE PROCEDURE»(ref-394513-S19948725612011040800000).
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 illuminated (2nd trip).
4. FREEZE FRAME DATA Freeze frame data record the engine conditions (fuel system, calculated engine load, engine coolant temperature, fuel trim, engine speed, vehicle speed, etc.) when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data, from the time the malfunction occurred.
5. DLC3 (Data Link Connector 3) The ECM uses ISO 15765-4 for communication. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format. Symbol (Terminal No.) Terminal Description Condition Specified Condition SIL (7) - SG (5) Bus "+" line During transmission Pulse generation CG (4) - Body ground Chassis ground Always Below 1 ohms SG (5) - Body ground Signal ground Always Below 1 ohms BAT (16) - Body ground Battery positive Always 11 to 14 V CANH (6) - CANL (14) CAN bus line Ignition switch off * 54 to 69 ohms CANH (6) - CG (4) HIGH-level CAN bus line Ignition switch off * 200 ohms or higher CANL (14) - CG (4) LOW-level CAN bus line Ignition switch off * 200 ohms or higher CANH (6) - BAT (16) HIGH-level CAN bus line Ignition switch off * 6 kohms or higher CANL (14) - BAT (16) LOW-level CAN bus line Ignition switch off * 6 kohms or higher NOTE: *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches or the doors. HINT: The DLC3 is the interface prepared for reading various data from the vehicle's ECM. After connecting the cable of a Techstream, turn the ignition switch to ON and turn the Techstream on. If the display indicates that a communication error has occurred, there is a problem either the vehicle or tester. In order to identify the location of the problem, connect the Techstream 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 Techstream itself. Consult the Service Department listed in the instruction manual for the Techstream.
6. BATTERY VOLTAGE Standard voltage 11 to 14 V If the voltage is below 11 V, replace or recharge the battery before proceeding
7. MIL (Malfunction Indicator Lamp) The MIL is illuminated when the ignition switch is first turned to 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 ignition switch is first turned to ON, check the MIL circuit. Refer to «MIL Circuit»(ref-394517-S09952225892011040800000).
8. ALL READINESS HINT: With All Readiness you can check whether or not the DTC judgment has been completed by using the Techstream. You should check All Readiness after simulating malfunction symptoms or for validation after finishing repairs. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear DTCs. Refer to «DTC CHECK / CLEAR»(ref-394513-S17742279252011040800000). Turn the ignition switch off and wait for at least 30 seconds. Turn the ignition switch to ON and turn the Techstream on. Perform the DTC judgment driving pattern to run the DTC judgment. Enter the following menus: Powertrain / Engine / 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 abnormal INCOMPLETE DTC judgment not completed 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 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 the Techstream. The Techstream can display the current, pending and permanent DTCs.
2. If a malfunction is detected during the current driving cycle, current and permanent DTCs are stored.
3. Some DTCs are not stored 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.
4. Current and pending DTCs can be cleared by using the Techstream or by disconnecting the cable from the negative battery terminal. However, permanent DTCs cannot be cleared using either of these two methods.
5. After clearing current DTCs using the Techstream (or by disconnecting the cable from the negative battery terminal), permanent DTCs can be cleared when the system is determined to be normal for the relevant DTCs and then the universal trip is performed. The driving pattern to obtain a normal judgment is described under the "CONFIRMATION DRIVING PATTERN" for the respective DTC.

2 TRIP DETECTION EXAMPLES

Scheme 18

Scheme 19

HINT

1. Obtaining a normal judgment and performing a universal trip driving pattern can be done in the same driving cycle or in different driving cycles.
2. It is unnecessary to obtain a normal judgment if the DTCs are misfire or fuel system DTCs.

1. CHECK DTC Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Check DTCs and freeze frame data, and then write them down. Check the details of DTCs. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-394513-S31071923012011040800000).
2. CLEAR DTC Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Clear DTCs.
3. CLEAR DTC (Without using Techstream) Perform either of the following operations: Disconnect the cable from the negative battery terminal for more than 1 minute. Remove the EFI and ETCS fuses from the engine room relay block located inside the engine compartment for more than 1 minute.
4. CLEAR PERMANENT DTC HINT: Even if the following procedure is not performed, permanent DTCs are cleared by obtaining a normal judgment during 3 consecutive driving cycles. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Check if permanent DTCs are stored. HINT: If permanent DTCs are not output, it is not necessary to continue this procedure. Clear DTCs. Perform the respective confirmation driving patterns in order to obtain a normal judgment for the output DTCs. HINT: Confirmation driving patterns do not need to be performed for misfire and fuel system DTCs. For the confirmation driving pattern, refer to the procedures for the relevant DTC. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-394513-S31071923012011040800000). Perform the universal trip. HINT: The driving pattern to obtain a normal judgment and the universal trip driving pattern can be performed consecutively in the same driving cycle. Idle the engine for 30 seconds or more. Drive the vehicle at 40 km/h (25 mph) or more for a total of 5 minutes or more. HINT: It is possible to complete the drive pattern even if the vehicle decelerates to less than 40 km/h (25 mph) during the driving cycle provided that the vehicle is driven at 40 km/h (25 mph) or more for a total of 5 minutes. Allow 10 minutes or more to elapse from the time the engine is started. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Check that the permanent DTCs have been cleared. HINT: The permanent DTCs are cleared when the universal trip is completed.

1. DESCRIPTION Freeze frame data record the engine conditions (fuel system, calculated load, engine coolant temperature, fuel trim, engine speed, vehicle speed, etc.) when a malfunction is detected. When troubleshooting, it can help determine if the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was Lean or Rich, and other data, from the time the malfunction occurred. HINT: If it is impossible to duplicate the problem even though a DTC is detected, confirm the freeze frame data. The ECM records engine conditions in the form of freeze frame data every 0.5 seconds. Using a 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 sets 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 the cause of the malfunction, and in judging whether it was temporary or not.

The Active Test can be performed with a Techstream. Performing an Active Test as the first step of troubleshooting is one method of shortening diagnostic time. Data List can be displayed during Active Test. 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. Perform the Active Test by referring to the table below. Tester Display Test Part Control Range Diagnostic Note Control the Injection Volume Change injection volume Between -12.5 and 24.8 % All injectors tested at same time Perform test at less than 3,000 rpm Injection volume can be changed in 0.1or 0.2 % graduations within control range Control the Injection Volume for A/F Sensor Change injection volume Decrease by 12.5 % or increase by 25 % Perform test at less than 3,000 rpm Control the Injection Volume for A/F Sensor enables checking and graphing of A/F (Air-Fuel Ratio) sensor and HO2 (Heated Oxygen) sensor voltage outputs To conduct test, enter the following menus: Active Test / Control the Injection Volume for A/F Sensor / Data List / A/ F Control System / AFS Voltage B1S1 / O2S B1S2 Activate the VSV for Evap Control Activate purge VSV control ON/OFF - Control the Fuel Pump / Speed Activate fuel pump (C/OPN Relay) ON/OFF Test possible when engine stopped Connect the TC and TE1 Turn on and off TC and CG (TE1) connection ON/OFF ON: TC and CG (TE1) connected OFF: TC and CG (TE1) disconnected Control the Idle Fuel Cut Prohibit Prohibit idling fuel cut control ON/OFF Idling fuel cut turned ON when throttle valve fully closed and engine speed over 2800 rpm Prohibit the Catalyst OT Misfire Prevent F/C Prohibit catalyst overheat malfunction prevention fuel cut operation during misfire ON/OFF Confirm that the vehicle is stopped and engine speed is 3000 rpm or less Control the Electric Cooling Fan Control Electric Cooling Fan ON/OFF - Activate the Starter Relay Starter ON/OFF Test possible when engine stopped Activate the ACC Cut Relay Active ACC (Accessory) relay ON/OFF Test possible when engine stopped Control the ETCS Open/Close Slow Speed Throttle actuator Close/Open Test possible when following conditions met: Engine stopped Shift position in P Fully depressing accelerator pedal (APP: 59 degrees or more) Control the ETCS Open/Close Fast Speed Throttle actuator Close/Open Open: Throttle valve opens quickly Same as above. Control the VVT Linear (Bank1) Control VVT (bank 1) -128 to 127 % This value added to present OCV control duty 100 %: Maximum advance -100 %: Maximum retard Engine stall or rough idle when VVT actuator operated by 100 %. Test possible while vehicle stopped and engine idling Control the VVT System (Bank1) Turn on and off OCV (Oil Control Valve) ON/OFF Engine stalls or idles roughly when OCV turned ON Normal engine running or idling when OCV OFF Test possible while vehicle stopped and engine idling Activate the Vacuum Pump Leak detection pump (built into canister assembly) ON/OFF - Activate the VSV for Vent Valve Vent valve (built into canister assembly) ON/OFF - Control the Cylinder #1 Fuel Cut Cylinder #1 injector fuel cut ON/OFF Test possible during vehicle stopping and engine idling*1 Control the Cylinder #2 Fuel Cut Cylinder #2 injector fuel cut ON/OFF Control the Cylinder #3 Fuel Cut Cylinder #3 injector fuel cut ON/OFF Control the Cylinder #4 Fuel Cut Cylinder #4 injector fuel cut ON/OFF Control the All Cylinders Fuel Cut All cylinder fuel cut ON/OFF Check the Cylinder Compression*2 Check the cylinder compression pressure (measuring engine speed for each cylinder) ON/OFF Both fuel injection and ignition stopped in all cylinders NOTE: *1: If the display of the Data List's 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's Catalyst OT MF F/C item is Avail, perform this Active Test as described below. Stop the engine, turn the ignition switch to ON and turn Control the Cylinder #1 Fuel Cut (to Control the Cylinder #4 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 ignition switch off. Connect a 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. Select the following monitor items: Compression / Engine Speed of Cyl #1 to #4, 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 #4 and Av Engine Speed of All Cyl change. Monitor the engine speed (Engine Speed of Cyl #1 to #4, Av Engine Speed of All Cyl) displayed on the Techstream. HINT: The Techstream displays extremely high values before cranking the engine. Each cylinder's engine speed is measured while cranking the engine and then the Techstream 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 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. Tester Display Test Part Control Range Diagnostic Note Evaporative System Check (Automatic Mode) EVAP key-off monitor Perform 5 steps in order to operate EVAP key-off monitor automatically Recommended Fuel Temperature: 35°C (95°F) or less If no DTCs in PENDING CODE after performing this test, system functioning normally Refer to EVAP system.
