Check For Intermittent Problems
WARNING: This page is about a different car, the 2008 Toyota FJ Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
Techstream only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with a Techstream when the ECM is in check mode. In check mode, the ECM uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detection logic.
- Clear DTCs (See DTC CHECK/CLEAR ).
- Switch the ECM from normal mode to check mode using a Techstream (See CHECK MODE PROCEDURE ).
- Perform a simulation test.
- Check and wiggle the harness(es), connector(s) and terminal(s).
