Toyota RAV4 (XA40) 2013-2018 Service Manual: Starter relay circuit high

Description
While the engine is being cranked, the 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 sets
the dtc.
This monitor runs when the vehicle is driven at 20 km/h (12.4 Mph) for over 20
seconds.
