ROAD TEST

1. PROBLEM SYMPTOM CONFIRMATION Based on the result of the customer problem analysis, try to reproduce the symptoms. If the problem is that the transmission does not shift up or down, or that the shift point is too high or too low, conduct the following road test referring to the automatic shift schedule and attempt to duplicate the problem symptoms.
2. ROAD TEST Perform a road test. WARNING: Check for safety before performing any tests. NOTE: Be sure to inspect and adjust the engine before performing these tests. Perform the road test with the engine coolant temperature between 60 and 100°C (140 and 212°F) and the ATF temperature between 50 and 100°C (122 and 212°F). Perform these tests with the air conditioning and cruise control off. Inspection Procedure Transmission Control Switch Test With the vehicle stationary and the shift lever in D (2), move the shift lever to 4 (L) and return it to D (2). Check that the meter display changes from D (2) to the appropriate 4 (L) and then back again. D Position Shift Test While driving the vehicle normally, check that the transmission shifts up and down through each gear properly. Lock-up Function While driving on a level surface at a constant speed in the lock-up range (75 km/h (47 mph) or more) with the shift lever in D, lightly depress the accelerator pedal and check that the engine speed does not change abruptly. P Position Test Stop the vehicle on an incline (approximately 5° or more). Then move the shift lever to P and release the parking brake. Check that the parking lock pawl holds the vehicle in place. Abnormal Noise and Vibration Check for abnormal noise and vibration while driving the vehicle forward and backward, and during shift operations. Fluid Leakage After performing all other road test inspections, check for fluid leakage.

1. DESCRIPTION When troubleshooting On-Board Diagnostic (OBD II) vehicles, the vehicle must be connected to the OBD II scan tool (complying with SAE J1987). Various data output from the vehicle's ECM can then be read. OBD II regulations require that the vehicle's on-board computer illuminates the Malfunction Indicator Lamp (MIL) on the instrument panel when the computer detects a malfunction in: The emission control system/components The powertrain control components (which affect vehicle emissions) The computer In addition, the applicable Diagnostic Trouble Codes (DTCs) prescribed by SAE J2012 are recorded in the ECM memory. When the malfunction does not reoccur, the MIL stays illuminated until the ignition switch is turned off, and the MIL turns OFF when the engine is started. However, the DTCs remain recorded in the ECM memory. To check DTCs, connect Techstream to the Data Link Connector 3 (DLC3) of the vehicle. The Techstream displays DTCs, the freeze frame data and a variety of the engine data. The DTCs and freeze frame data can be erased with the Techstream.Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-493476-S33470625122012081000000) .
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 to technicians as an option. In check mode, "1 trip detection logic" is used for simulating malfunction symptoms and increasing the system's ability to detect malfunctions, including intermittent malfunctions.
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 drive cycle, the MIL is illuminated (2nd trip).
4. FREEZE FRAME DATA Freeze frame data records the engine conditions (fuel system, calculated load, engine coolant temperature, fuel trim, engine speed, vehicle speed, etc.) when a malfunction is 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. Techstream records freeze frame data in 5 different instances: 1) 3 times before the DTC is set, 2) once when the DTC is set, and 3) once after the DTC is set. These data can be used to simulate the vehicle's condition around the time when the malfunction occurred. The data may help find the cause of the malfunction, or judge if the DTC is being caused by a temporary malfunction or not.
5. DATA LINK CONNECTOR 3 (DLC3) 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. TERMINAL OF DLC3 Symbols (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) - Battery positive HIGH-level CAN bus line Ignition switch off* 6 kohms or higher CANH (6) - CG (4) HIGH-level CAN bus line Ignition switch off* 200 ohms or higher CANL (14) - Battery positive LOW-level CAN bus line Ignition switch off* 6 kohms or higher CANL (14) - CG (4) LOW-level CAN bus line Ignition switch off* 200 ohms 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. If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector. HINT: Connect the cable of Techstream to the DLC3, turn the ignition switch to ON and attempt to use the Techstream. If the screen displays UNABLE TO CONNECT TO VEHICLE, a problem exists in the vehicle side or the Techstream side. If communication is normal when the Techstream is connected to another vehicle, inspect the DLC3 on the original vehicle. If communication is still not possible when the Techstream is connected to another vehicle, the problem is probably in the Techstream itself. Consult the Service Department listed in the Techstream's instruction manual.
6. CHECK MIL Check that the MIL illuminates when turning the ignition switch to ON. If the MIL does not illuminate, there is a problem in the MIL circuit.Refer to «MIL Circuit»(ref-493463-S41260471082012081000000) . When the engine is started, the MIL should turn off.
7. ALL READINESS For this vehicle, using Techstream allows readiness codes corresponding to all DTCs to be read. When the diagnosis (normal or malfunctioning) has been completed, readiness codes are set. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

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.

4. CLEAR PERMANENT DTC HINT: Even if the following procedure is not performed, permanent DTCs are cleared if no malfunction is detected 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 universal trip. 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. When accelerating through the gears, make sure the vehicle is driven so all gears are used in order and no gears are skipped. Allow 10 minutes or more to elapse from the time the engine is started. Turn the ignition switch off. Wait 15 seconds. Turn the ignition switch to ON. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Check that the permanent DTCs have been cleared. HINT: If the permanent DTCs have not been cleared, perform the universal trip again. The permanent DTCs are cleared when the universal trip is completed.
