DTC P0C57-00: Electric Motor Resolver Signal: Out Of Normal Determination Range (Low Side)

WARNING: <<High voltage>>

• If the necessary measures are not taken before servicing an electric vehicle, it could cause electrical shock and result in serious injury or, in the worst case, death. Before servicing the electric vehicle, refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in the general information and implement the necessary measures. (Refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in service information).

P0C57-00: (SGC2/DMCM (E-SKYACTIV PHEV)) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Electric motor resolver signal: Out of normal determination range (LOW side)
Detection condition	The drive motor control module detects that the sine signal voltage output by the resolver in the electric motor is the standard value or less.
Fail-safe	Stops the electric motor.
Possible cause	WARNING: <<High voltage>> If necessary measures such as wearing the correct protective gear are not taken when inspecting or removing/installing the high voltage parts, it could cause electrical shock and result in serious injury or, in the worst case, death. Before inspecting or removing/installing the high voltage parts, refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in the general information and [High Voltage Part Inspection and Removal/Installation Notes] of the high voltage system service cautions and implement the necessary measures and preparations. (Refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in service information). (Refer to [HIGH VOLTAGE SYSTEM SERVICE CAUTIONS ] in service information). Wear insulated gloves when working on a high voltage system. Malfunction in wiring harness (including connector/terminal) between electric motor (3002-303A connector) and drive motor control module (3002-302A connector) (See CIRCUIT INSPECTION .) (See CONNECTOR INSPECTION .) Electric motor malfunction (electric motor speed sensor malfunction) (Refer to [ELECTRIC MOTOR INSPECTION ] in service information). Drive motor control module malfunction (Refer to [INVERTER REMOVAL/INSTALLATION ] in service information).
Repeatability verification procedure	Clear the DTC recorded in the memory. (See CLEARING DTC .) WARNING: Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured. Drive the vehicle for 10 min or more.
