DTC P0615-19: Starter Relay Circuit Current Above Threshold [11/2016 - ]: Description

WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.

When the engine is started by stop and start control, the engine stop and start ECU controls the starter assembly by activating the ST relay (for starter pinion operation) via voltage from terminal STA and then, using its built-in starter delay circuit, activating the ST NO. 2 relay (for starter motor operation) via voltage from terminal STA2.

If overcurrent is detected in the starter relay circuit, the engine stop and start ECU stores DTC P061519 and blinks the stop and start cancel indicator.
