TESTING PROCEDURE

To ensure correct diagnosis and repair, testing should be done in the following sequence

  1. Record Customer Complaint - Ensure all customer complaints or observations are recorded. Test drive vehicle with customer when necessary for malfunction verification.
  2. Retrieve Diagnostic Trouble Codes - Using Toyota hand-held tester or scan tool, retrieve Diagnostic Trouble Codes (DTC) from Engine Control Module (ECM) and record any freeze frame data (if applicable). See «RETRIEVING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-2002-2005/remont/testing-diagnostics/#engine-control-system-self-diagnostics-land-cruiser__retrieving-diagnostic-trouble-codes) .
  3. Clear Diagnostic Trouble Codes - Using Toyota hand-held tester or scan tool, clear DTCs and freeze frame data from ECM. See «CLEARING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-2002-2005/remont/testing-diagnostics/#engine-control-system-self-diagnostics-land-cruiser__clearing-diagnostic-trouble-codes) .
  4. Visual Inspection - Inspect all electrical connectors and wiring for suspected circuit or component. Ensure all connections are clean and tight.
  5. Confirm Symptoms & Diagnostic Trouble Codes - Perform road test. Determine if original symptoms still exist. Using scan tool or Toyota hand-held tester, retrieve DTCs from ECM. See «RETRIEVING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-2002-2005/remont/testing-diagnostics/#engine-control-system-self-diagnostics-land-cruiser__retrieving-diagnostic-trouble-codes) .
  6. Diagnose & Repair Diagnostic Trouble Codes - Perform appropriate DTC test listed under DIAGNOSTIC TESTS as necessary.

If no DTCs are present and a no start condition exists, proceed to «BASIC DIAGNOSTIC PROCEDURES - V6 & V8»(/toyota/land-cruiser/100-2002-2005/remont/testing-diagnostics/#engine-controls-basic-diagnostic-procedures-v6-v8) article. If no DTCs are present and a driveability condition exists, proceed to «TROUBLESHOOTING - NO CODES»(/toyota/land-cruiser/100-2002-2005/remont/testing-diagnostics/#engine-controls-trouble-shooting-no-codes) article for diagnosis by symptom (i.e., ROUGH IDLE, ENGINE STALLS, etc.).
  7. Verification Procedure - After repairs have been completed, clear all DTCs from ECM. See «CLEARING DIAGNOSTIC TROUBLE CODES»(/toyota/land-cruiser/100-2002-2005/remont/testing-diagnostics/#engine-control-system-self-diagnostics-land-cruiser__clearing-diagnostic-trouble-codes) .
