Monitor Description
WARNING: This page is about a different car, the 2015 Lexus IS 250 and 2014 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.
While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM.
If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores this DTC.
This monitor runs when the vehicle is driven at 20 km/h (12.43 mph) or more for 20 seconds or more.
