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

WARNING: This page is about a different variant/trim than selected.

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.
