DTC P1586: Acceleration Sensor Malfunction [01/2019 - 11/2022]: Description
WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, and 2019 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
The ECM determines the vehicle inclination based on a signal from the yaw rate and acceleration sensor. If a malfunction is determined in the yaw rate and acceleration sensor (airbag sensor assembly) based on a malfunction signal from the skid control ECU (brake actuator assembly), the ECM stores this DTC.
HINT:
- The signal of the yaw rate and acceleration sensor (airbag sensor assembly) is sent to the skid control ECU (brake actuator assembly) via the CAN communication system.
- If CAN communication DTCs are output, perform troubleshooting for those DTCs first.
