Check For Intermittent Problems [11/2018 - 08/2020]
WARNING: This page is about a different car, the 2020 Toyota RAV4 and 2019 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
Inspect the vehicle ECM using check mode. Intermittent problems are easier to detect with the 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 the DTCs.
- Change the ECM from normal mode to check mode using the Techstream.
- Perform a simulation test.
- Check and wiggle the harness(es), connector(s) and terminal(s).
