DTC P1586: Acceleration Sensor Malfunction: 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.

DTC No.	DTC Detection Condition Diagnosis Condition Malfunction Status Malfunction Time Other	Trouble Area
P1586	Ignition switch ON With the vehicle speed 30 km/h (18 mph) or more, the difference between longitudinal G calculated based on the G sensor value and longitudinal G calculated based on the vehicle speed exceeds 0.35 G for 60 seconds or more. Condition 2 is determined for 3.0 seconds or more. 1-trip detection logic	Yaw rate and acceleration sensor Brake actuator assembly (Skid control ECU) CAN communication system
P1586	Ignition switch ON The yaw rate and acceleration sensor signal does not change 16 times or more while the vehicle speed decreases from 30 km/h (18 mph) to 0 km/h. Condition 2 is determined for 3.0 seconds or more. 1-trip detection logic
