Monitor Description
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.
The TCM assumes that the vehicle is being driven when the transmission counter gear indicates more than 300 rpm and over 30 seconds have passed since the park/neutral position switch assembly was turned off. If there is no vehicle speed signal with these conditions satisfied, the TCM concludes that there is a vehicle speed signal malfunction. The TCM will illuminate the MIL and store this DTC.
