DTC P0615-19: Starter Relay Circuit Current Above Threshold [08/2020 - 12/2021]: Description

When the engine is started by stop and start control, the engine stop and start ECU controls the starter assembly by activating the ST NO. 1 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 P0615-19 and blinks the stop and start cancel indicator.
