TWO-TRIP DETECTION LOGIC
Note. When road testing vehicle in CHECK mode (Toyota hand-held tester only), Two-Trip Detection Logic will not function. Also, MIL will illuminate first time a malfunction is detected.
When a malfunction initially occurs, Diagnostic Trouble Code (DTC) will be temporarily stored in ECM memory, but MIL on instrument panel will not illuminate. The second time malfunction is detected, MIL on instrument panel will illuminate, provided ignition is turned off and then back on after first malfunction was detected. This is referred to as "Two-Trip Detection Logic" and only applies to specific DTCs.
DATA LINK CONNECTOR
OBD-II regulations (SAE J-1850) standardizes Data Link Connector (DLC) configurations. See DATA LINK CONNECTOR (DLC) NO. 3 LOCATION table. See appropriate figure in appropriate SELF-DIAGNOSTICS article.
| Model | Location |
|---|---|
| Avalon, Camry, Camry Solara, Celica, Corolla & ECHO | Left Side Of Instrument Panel, Left Of Steering Column |
| Land Cruiser, RAV4, Sienna, Tacoma, Tundra & 4Runner | Left Side Of Instrument Panel, Right Of Steering Column |
DATA LINK CONNECTOR (DLC) NO. 3 LOCATION
FREEZE-FRAME DATA
OBD-II or Toyota hand-held tester can by used to check freeze-frame data. ECM records engine operating condition when a misfire, fuel trim (mixture) malfunction or other malfunction (fuel system, calculated load, coolant temperature, fuel trim (mixture), engine speed, vehicle speed, etc.) exists. If more than one fault is detected, only data from the first malfunction is recorded. Recorded data is useful for determining conditions during which the malfunction occurred.
NORMAL Mode Code Retrieval
- Connect scan tool to Data Link Connector (DLC) No. 3. Turn ignition on with engine off. Turn scan tool on. Using scan tool manufacturer's instructions, check for DTCs and freeze-frame data.
- If scan tool displays UNABLE TO CONNECT TO VEHICLE, check DLC No. 3. See «DLC NO. 3 INSPECTION»(ref-3290-S12132391632000042000000) under SCAN TOOL PROBLEMS. If scan tool does not display UNABLE TO CONNECT TO VEHICLE, go to next step.
- Record any DTCs and freeze-frame data displayed for system diagnosis. If driveability problem exists and no DTCs are present, go to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom.
- If any DTCs are present, perform appropriate DTC test under DIAGNOSTIC TESTS in appropriate SELF-DIAGNOSTICS article. See appropriate DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table. For more information on freeze-frame data, see «FREEZE-FRAME DATA»(ref-3290-S20492968022000042000000) under INTRODUCTION. For information on 2-trip detection logic codes, see «TWO-TRIP DETECTION LOGIC»(ref-3290-S36482127472000042000000) under INTRODUCTION.
- After repairs have been completed, clear DTCs from ECM. See «CLEARING DIAGNOSTIC TROUBLE CODES»(ref-3290-S27048352252000042000000) . Road test vehicle to ensure all symptoms and/or complaints have been repaired.
CHECK Mode Code Retrieval (Toyota Hand-Held Tester Only)
Note. If ignition switch is turned from ON to ACC or OFF position, all DTCs and freeze-frame data will be erased. DO NOT switch modes until all DTCs and freeze-frame data are recorded.
- Ensure vehicle battery is fully charged. Apply parking brake. Shift transmission/transaxle into Neutral (M/T) or Park (A/T). Turn A/C and all accessories off. Ensure throttle valve is fully closed. Turn ignition off. Connect scan tool to Data Link Connector (DLC) No. 3. Turn ignition on with engine off. Turn scan tool on.
- Switch scan tool from NORMAL mode to CHECK mode. CHECK mode is operational if MIL on instrument cluster flashes. Start engine. If no DTCs are present, MIL will turn off. Try to simulate conditions of driveability complaint described by customer.
- Record any DTCs and freeze-frame data displayed for system diagnosis. If driveability problem exists and no codes are present, go to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom.
- If any DTCs are present, perform appropriate DTC test. See appropriate DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table. For more information on freeze-frame data, see «FREEZE-FRAME DATA»(ref-3290-S20492968022000042000000) under INTRODUCTION. For information on 2-trip detection logic codes, see «TWO-TRIP DETECTION LOGIC»(ref-3290-S36482127472000042000000) under INTRODUCTION.
- After repairs for DTC have been completed, DTC must be cleared from ECM memory. See «CLEARING DIAGNOSTIC TROUBLE CODES»(ref-3290-S27048352252000042000000) . Road test vehicle to ensure all symptoms and/or complaints have been repaired.
