Monitor Description

WARNING: This page is about a different car, the 2024 Lexus TX 500h. However, it is still accessible from the selected car via links, so may be relevant.

If the SP1 vehicle speed signal from the skid control ECU is 0 km/h (0 mph) or less, even though the vehicle is being driven (vehicle driving ON flag received from the TCM), the ECM illuminates the MIL and stores a DTC.
