2004 LAND CRUISER (RM1071U)
DTC P0617 Starter Relay Circuit High
MONITOR DESCRIPTION
While the engine is being cranked, the battery positive voltage is applied to terminal STA of the ECM.
If the vehicle is being driven and the ECM detects the starter control signal (STA), the ECM concludes that
the starter control circuit is malfunctioning. The ECM will turn on the MIL and a DTC is set.
