Intermittent Problems Check (Hand-Held Tester Only)

WARNING: This page is about a different car, the 2003 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

By putting the vehicle's ECM in the check mode, one-trip detection logic is possible instead of 2-trip detection logic and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.

  1. Clear the DTC. See CLEARING DIAGNOSTIC TROUBLE CODES .
  2. Set the check mode. See CHECK MODE DTC RETRIEVAL (HAND-HELD TESTER ONLY)  under RETRIEVING DIAGNOSTIC TROUBLE CODES.
  3. Simulate the conditions of the malfunction described by customer
  4. Check the connector and terminal.
  5. Handle the connector.
