If no faults were found while performing BASIC DIAGNOSTIC PROCEDURES, proceed with self-diagnostics. If no Diagnostic Trouble Codes (DTCs) are present after entering self-diagnostics, proceed to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).
SYSTEM OVERVIEW
Engine Control Module (ECM) monitors engine operation and contains a self-diagnostic system which stores Diagnostic Trouble Codes (DTCs) and complies to On-Board Diagnostics Generation II (OBD-II) standards.
Self-diagnostic system is used to provide vehicle with an on-board diagnostic system which is capable of continuously monitoring efficiency of emission control system, and improving diagnosis and repair when system failures occur.
Federal Test Procedure (FTP) sets maximum allowable emission standards. A Malfunction Indicator Light (MIL) must illuminate if a system or component either fails or deteriorates to a point where the vehicle emissions could increase to more than 1 1/2 times FTP standards.
If malfunction does not recur in 3 ignition cycles, MIL goes off, but DTCs remain recorded in ECM memory. DTCs may only be retrieved using an On-Board Diagnostic-II (OBD-II) scan tool that complies with SAE standard J-1978 or Toyota hand-held tester connected to Data Link Connector (DLC) No. 3. Scan tool also provides freeze-frame data and can be used to clear codes.
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.

MALFUNCTION INDICATOR LIGHT (MIL) INSPECTION
Note. CHECK engine light, located on instrument cluster, is referred to as Malfunction Indicator Light (MIL). Inspect MIL to ensure it is operational and will come on if a Diagnostic Trouble Code (DTC) is set.
- Turn ignition on with engine off. MIL should come on and remain on. If MIL comes on, go to next step. If MIL does not come on, check bulb circuit on instrument cluster and wiring circuit between MIL and ECM. See appropriate wiring diagram in WIRING DIAGRAMS article. See «ECM LOCATION»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__ecm-location) .
- Start engine and ensure MIL goes off. If MIL goes off, no malfunction is detected at this time. If MIL remains on or blinks with engine running, a malfunction is detected. Proceed to «RETRIEVING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__retrieving-diagnostic-trouble-codes) .
TESTING PROCEDURE
To ensure correct diagnosis and repair, testing should be done in the following sequence
- Record Customer Complaint - Ensure all customer complaints or observations are recorded. Test drive vehicle with customer when necessary for malfunction verification.
- Retrieve Diagnostic Trouble Codes - Connect appropriate scan tool to Data Link Connector No. 3. Retrieve codes and record any freeze-frame data (if applicable). See «RETRIEVING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__retrieving-diagnostic-trouble-codes) .
- Clear Trouble Codes - Clear codes and freeze frame data. See «CLEARING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__clearing-diagnostic-trouble-codes) .
- Visual Inspection - Inspect all connectors of suspect circuit or component. Ensure all connections are clean and tight.
- Confirm Symptoms & Trouble Codes - Perform road test. Determine if original symptoms are still present. Retrieve codes. See «RETRIEVING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__retrieving-diagnostic-trouble-codes) .
- Diagnose & Repair Diagnostic Trouble Codes - Perform diagnosis and repair procedures as necessary. See appropriate SELF-DIAGNOSTICS article. If no codes are present, proceed to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).
- Verification Procedure - After repairs have been completed, clear all diagnostic trouble codes. See «CLEARING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__clearing-diagnostic-trouble-codes) . Perform road test. Ensure no codes are present and all symptoms and/or complaints have been repaired.
RETRIEVING DIAGNOSTIC TROUBLE CODES
Note. Diagnostic Trouble Codes (DTCs) may be retrieved using Toyota hand-held tester or On-Board Diagnostic (OBD-II) scan tool that complies with SAE standard J-1978. Toyota hand-held tester or OBD-II scan tool may be operated in NORMAL mode when retrieving trouble codes. Only Toyota hand-held tester may be used in CHECK mode when retrieving DTCs.
NORMAL mode is used to retrieve DTCs from Engine Control Module (ECM). CHECK mode is used to check for DTCs when operating vehicle to simulate conditions during which DTC was set. CHECK mode contains a higher sensing ability to detect malfunctions. CHECK mode helps determine malfunctions caused by poor electrical connections, which are difficult to determine using NORMAL mode.
Note. If using Toyota hand-held tester, when ignition switch is turned from ON to ACC or OFF position, or scan tool is switched from NORMAL mode to CHECK mode, all DTCs and freeze-frame data will be erased. DO NOT switch modes until all DTCs and freeze-frame data have been recorded.
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»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__dlc-no-3-inspection) 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»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__freeze-frame-data) under INTRODUCTION. For information on 2-trip detection logic codes, see «TWO-TRIP DETECTION LOGIC»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__two-trip-detection-logic) under INTRODUCTION.
- After repairs have been completed, clear DTCs from ECM. See «CLEARING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__clearing-diagnostic-trouble-codes) . 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»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction__freeze-frame-data) under INTRODUCTION.

DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION (4RUNNER V6)
CLEARING DIAGNOSTIC TROUBLE CODES
- After performing repairs, clear Engine Control Module (ECM) memory of all stored Diagnostic Trouble Codes (DTCs) and freeze-frame data. DTCs and freeze-frame data may be cleared by using scan tool and scan tool manufacturer's instructions.
- DTCs and freeze-frame data may also be cleared by removing EFI fuse from fuse block located in engine compartment. DTCs and freeze-frame data may also be cleared by disconnecting negative battery cable. However, other memory functions (clock, radio, alarm, seats, etc.) will be cleared and must be reset.
TROUBLE CODE TEST DRIVE CONFIRMATION
- On certain Diagnostic Trouble Codes (DTCs), once DTC has been cleared from ECM memory, a DTC test drive confirmation test can be performed to verify repairs made and that DTC does not reset. Test drive confirmation test will duplicate conditions required to set specified DTCs.
- Test drive confirmation test lists the procedure to be performed to check that DTC does not reset. Test drive confirmation tests apply only to specific DTCs. Test drive confirmation test will be included with proper DTC test in appropriate SELF-DIAGNOSTICS article.
DLC NO. 3 INSPECTION
- If scan tool displays UNABLE TO CONNECT TO VEHICLE when scan tool is connected, try scan tool on another vehicle. If scan tool operates on another vehicle, go to next step. If scan tool does not operate on another vehicle, problem is probably with scan tool.
- Check DLC No. 3 for loose or damaged terminals. Ensure DLC No. 3 terminals are in correct position in connector. See appropriate wiring diagram in WIRING DIAGRAMS article. Repair as necessary. If connector and terminals are okay, go to next step.
- Check voltage and resistance between ground and specified terminal on DLC No. 3. See «DLC NO. 3 VOLTAGE & RESISTANCE SPECIFICATIONS»(/toyota/land-cruiser/100-1998-2002/remont/testing-diagnostics/#engine-control-system-self-diagnostics-introduction) table. (Scheme 216) If voltage and resistance readings are not as specified, check wiring circuit. See appropriate wiring diagram in WIRING DIAGRAMS article.
