WARNING: This page is about a different car, the 2016 Toyota Highlander, 2015 Toyota Highlander, and 2014 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
- Refer to inspection procedure for CAN communication system.
- If the CAN communication system is malfunctioning, the TCM cannot receive current data from the ECM. In this case, the freeze frame data output from the TCM has not been updated, so it will not be useful for inspection. However, reading the Data List as the first step in troubleshooting is effective to find malfunctions.
- The malfunction area can be checked using the Bus Check function on the Techstream.
