How TO Use Flow Charts

  1. Use appropriate trouble shooting flow chart corresponding to fault code. Test Harness (07LAJ-PT3010A) and Adapter (07MAZ-PY4010A) may be required when using flow charts. Modify test harness before connecting, using knife to cut bars off each side of test harness "A" connector. This is the 26-pin connector on test harness.
  2. To connect test harness, ensure ignition is off. Remove door sill molding on passenger's side and remove small cover on passenger's side kick panel. Pull carpet back for access to PCM. Remove PCM cover, located above PCM.
    NOTE: On some flow charts, technician will be instructed to connect test harness to only specified connector and NOT the PCM. Reference is made in flow chart to E(26P) connector. This is "E" connector on left side of PCM. See Fig 1 .
  3. If connecting to PCM, disconnect "E" connector from left side of PCM. See Fig 1 . This is 26-pin connector used for transaxle control.
  4. Connect test harness "A" connector to "E" connector opening on left side of PCM. Install adapter between test harness and "E" connector on wiring harness. See Fig 2 . Disconnect necessary wiring connectors on right side of PCM and connect to test harness.
  5. Use Digital Volt-Ohmmeter (DVOM) to measure voltage unless instructed otherwise. Terminal numbers are located on top of test harness. Test harness is divided into different sections.
    NOTE: The "A" section of test harness and cable adapter corresponds to "E" 26-pin connector on PCM.
  6. On some fault code trouble shooting flow charts, technician will be instructed to see if Malfunction Indicator Light (MIL) is blinking. The MIL is located on instrument panel. See Figure .
  7. If MIL is blinking, PGM-FI system must be checked. See the appropriate TESTS W/CODES article in the ENGINE PERFORMANCE section.
  8. Once all repairs are performed, remove test harness and adapter and reinstall components. Ensure fault code is cleared from PCM memory. See CLEARING CODES  under SELF-DIAGNOSTIC SYSTEM.
