DTC P1585: Acceleration Sensor Circuit: Description
The ECM determines the vehicle inclination based on a signal from the yaw rate and acceleration sensor to perform neutral control. If a malfunction is determined in the yaw rate and acceleration sensor based on a malfunction signal from the brake actuator assembly, the ECM cancels neutral control as a fail-safe function.
HINT:
- The ECM receives a yaw rate and acceleration sensor signal from the brake actuator assembly via CAN communication.
- If a CAN communication DTC is output, perform troubleshooting for that DTC first.
