Check For Intermittent Problems
WARNING: This page is about a different car, the 2006 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
Intelligent tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect when the ECM is in check mode with the intelligent tester. In check mode, the ECM uses 1 trip detection logic, which has a higher sensitivity to malfunctions than normal mode (default), which uses 2 trip detection logic.
- Clear the DTCs (See DTC CHECK/CLEAR ).
- Set the check mode (See DTC CHECK/CLEAR ).
- Perform a simulation test (See HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS ).
- Check the connector and terminal (See ELECTRONIC CIRCUIT INSPECTION PROCEDURE ).
- Wiggle the harness and the connector (See ELECTRONIC CIRCUIT INSPECTION PROCEDURE ).
