Code P0617 2001 Toyota Highlander Description

While the engine is being cranked, the positive battery voltage is applied to terminal Starter Control (STA) of the Engine Control Module (ECM). If the ECM detects the Starter Control 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 Diagnostic Trouble Code (DTC).
