1. DESCRIPTION When troubleshooting OBD II (On-Board Diagnostics) vehicles, an OBD II scan tool (complying with SAE J1987) must be connected to the DLC3 (Data Link Connector 3) of the vehicle. Various data in the vehicle ECM (Engine Control Module) can be then read. OBD II regulations require that the vehicle on-board computer illuminates the MIL (Malfunction Indicator Lamp) on the instrument panel when the computer detects a malfunction in: The emission control system and 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 cleared 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.
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 subsequent drive cycle, the MIL is illuminated (2nd trip).
4. DLC3 (Data Link Connector 3) Check DLC3. Refer to «GENERAL INFORMATION»(ref-393046-S10153232872011040700000) .
5. 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.
6. BATTERY VOLTAGE Standard voltage 11 to 14 V If voltage is below 11 V, replace or recharge the battery.
7. MIL (Malfunction Indicator Lamp) The MIL illuminates when the power 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 does not illuminate when the power switch is first turned on (IG), check the MIL circuit. Refer to «MIL Circuit»(ref-393184-S26344047072011040700000) .
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 power switch on (IG). Turn the Techstream on. Clear DTCs. Refer to «DTC CHECK / CLEAR»(ref-393183-S13119469612011040700000) . Turn the power switch off and wait for 30 seconds. Turn the power switch on (IG) and turn the Techstream on. Perform the DTC judgment driving pattern to run the DTC judgment. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness. Input the DTCs to be confirmed. Check the DTC judgment result. TECHSTREAM Techstream Display Description NORMAL DTC judgment completed System normal ABNORMAL DTC judgment completed System abnormal INCOMPLETE DTC judgment not completed Perform the driving pattern after confirming the 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 cleared. 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 122

Scheme 123

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.

Scheme 124

1. CHECK DTC Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on. Enter the following menus: 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-393183-S20320380732011040700000) .
2. CLEAR DTC (Pending and Current DTC) Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Clear the DTCs.
3. CLEAR DTC (Pending and Current 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 MAIN 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 power switch on (IG). 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-393183-S20320380732011040700000) . Perform the universal trip. HINT: The driving pattern to obtain a normal judgment and the universal trip driving can be performed consecutively in the same driving cycle. Put the engine in inspection mode. Refer to «INSPECTION MODE PROCEDURE»(ref-393046-S20890913792011040700000) . Idle the engine for 30 seconds or more. Drive the vehicle at 25 mph (40 km/h) 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 25 mph (40 km/h) during the driving cycle provided that the vehicle is driven at 25 mph (40 km/h) 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.

Scheme 125

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 moving or stationary, 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 the malfunction. The data may assist in identifying the cause of the malfunction, and judging whether it was temporary or not.

HINT: *: While the Active Test item Check the Cylinder Compression is being performed, if one cylinder's speed is higher than the others, that cylinder's compression pressure can be concluded to be lower than the others. Connect the Techstream to the DLC3. Turn the power switch on (IG) and turn the Techstream on. Put the engine in inspection mode. Refer to «INSPECTION MODE PROCEDURE»(ref-393046-S20890913792011040700000) . Start the engine and warm it up. Turn the power switch off. Turn the power switch on (IG) and turn the Techstream on. Put the engine in inspection mode. Refer to «INSPECTION MODE PROCEDURE»(ref-393046-S20890913792011040700000) . HINT: Do not start the engine. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression. HINT: If the results are not displayed normally, select the display items from the Data List before performing the Active Test. Enter the following menus: Powertrain / Engine and ECT / Compression / Engine Speed of Cyl #1 to #4 and Av Engine Speed of All Cyl. While the engine is not running, press the RIGHT or LEFT button to change the Check the Cylinder Compression to ON. Start the engine. Monitor the engine speed (Engine Speed of Cyl #1 to #4, Av Engine Speed of All Cyl) displayed on the Techstream. HINT: At first, the Techstream display will show each cylinder's engine speed measurement to be extremely high. After the engine started, each cylinder's engine speed measurement will change to the actual engine speed. NOTE: When the Check the Cylinder Compression Active Test is ON and the engine will start. If the Check the Cylinder Compression Active Test needs to be performed after it is turned ON and performed once, press EXIT to return to the Active Test menu screen. Then perform the Check the Cylinder Compression Active 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 power switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Utility. Perform the System Check by referring to the table below.
