DTC C15A3/63: Motor Rotation Angle Not Detected; DTC C15C5/69: Motor Rotation Signal Not Detected [08/2015 - ]: Description

The steering actuator assembly drives the internal motor using the current output from the VGRS ECU (steering control ECU) to change the relative angle between the tire angle and steering wheel angle.

The motor rotation angle sensor in the steering actuator assembly detects the motor rotation angle and outputs this information to the VGRS ECU (steering control ECU).

If the VGRS ECU (steering control ECU) detects a malfunction in the motor rotation angle sensor circuit, it stores DTC C15A3/63.

The test mode DTC C15C5/69 is only stored during test mode.

DTC No.	DTC Detection Condition	Trouble Area
C15A3/63	All conditions are met for approximately 0.03 seconds or more: 2 seconds or more elapse after turning the engine switch on (IG). 2 seconds or more elapse with the power source voltage at 10 V or higher. A problem with the motor rotation angle sensor is detected.	Steering actuator assembly VGRS ECU (steering control ECU) Harness or connector
