DTC P1586: Acceleration Sensor Malfunction [08/2013 - 08/2016]: Description

The ECM determines the vehicle inclination based on a signal from the airbag sensor assembly (yaw rate and acceleration sensor). If a malfunction of the airbag sensor assembly (yaw rate and acceleration sensor) is determined based on a malfunction signal from the brake actuator assembly (skid control ECU), the ECM cancels neutral control as a fail-safe function.

HINT:

The airbag sensor assembly (yaw rate and acceleration sensor) signal is sent to the brake actuator assembly (skid control ECU) via CAN communication.
If CAN communication DTCs are output, perform troubleshooting for those DTCs first.

Malfunction Status At a vehicle speed 30 km/h (18 mph) or more, the difference between longitudinal G calculated based on the airbag sensor assembly (yaw rate and acceleration sensor) (G sensor) value and longitudinal G calculated based on the vehicle speed exceeds 0.35 G for 60 seconds or more. Malfunction Time 3 seconds or more Other 1-trip detection logic Diagnosis Condition The ignition switch is ON. Malfunction Status The airbag sensor assembly (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 (0 mph).
