P1586

K41B CVT: CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: P1586: Acceleration Sensor Malfunction
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.
