1. DESCRIPTION When troubleshooting OBD II (On-Board Diagnostics) vehicles, the 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 then be 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 systems components. The powertrain control components (which affect vehicle emissions). The computer itself. In addition, the applicable DTCs prescribed by SAE J2012 are recorded in the ECM memory. If the malfunction does not recur in 3 consecutive trips, the MIL turns off automatically but the DTCs remain recorded in the ECM memory. To check the 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. In order to enhance OBD function on vehicles and develop the Off-Board diagnosis system, Controller Area Network (CAN) communication is used in this system. CAN is a network which uses a pair of data transmission lines spanning multiple computers and sensors. It allows for high speed communications between the systems and simplification of the wire harness connections. Since this system is equipped with CAN communication, connecting the CAN Vehicle Interface Module (VIM) with the Techstream is necessary to display any information from the ECM. Also, communications between the Techstream and ECM are performed through CAN communication signals. When confirming DTCs and any data of the ECM, connect the CAN VIM between the DLC3 and the Techstream.
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 (the 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 illuminated (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. CHECK DLC3 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. Symbols (Terminal No.) Terminal Description Condition Result 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 Engine switch off 54 to 69 ohms CANH (6) - CG (4) HIGH-level CAN bus line Engine switch off 200 ohms or higher CANL (14) - CG (4) LOW-level CAN bus line Engine switch off 200 ohms or higher CANH (6) - BAT (16) HIGH-level CAN bus line Engine switch off 6 kohms or higher CANL (14) - BAT (16) LOW-level CAN bus line Engine 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 engine 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 the Techstream, turn the engine switch on (IG) and turn the Techstream on. If a communication failure message is displayed on the Techstream screen, a problem exists in either the vehicle or the Techstream. 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.
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 (IG) (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 (IG), check the MIL circuit. Refer to «MIL Circuit»(ref-382724-S07484092142011012800000).
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 engine switch on (IG). Turn the Techstream on. Clear the DTCs. Refer to «DTC CHECK / CLEAR»(ref-382723-S32023580312011012800000). Perform the DTC judgment driving pattern to run the DTC judgment. Select the following menu items: 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 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 the Techstream. The 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 the Techstream) Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Select 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-382723-S22399221492011012800000).
2. CLEAR DTC (Using the Techstream) Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Select the following menu items: Powertrain / Engine and ECT / Trouble Codes. Press the YES button.
3. CLEAR DTC (Without using the 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 No. 2 engine room relay block, junction block located inside the engine compartment for more than 1 minute.

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 form of freeze frame data every 0.5 seconds. Using the 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 of the cause of the malfunction, and in judging whether it was temporary or not.
