DTC P1585: Acceleration Sensor Circuit [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 in 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 The output value of the airbag sensor assembly (yaw rate and acceleration sensor) remains at -1.5 G or less, or 1.5 G or more for 1.2 seconds or more. Malfunction Time 0.5 seconds or more Other 1-trip detection logic Diagnosis Condition The ignition switch is ON. Malfunction Status The power source voltage to the airbag sensor assembly (yaw rate and acceleration sensor) remains at 4.4 V or less, or 5.6 V or higher for 1.2 seconds or more. Malfunction Time 0.5 seconds or more Other 1-trip detection logic Diagnosis Condition The ignition switch is ON. Malfunction Status No signal from the airbag sensor assembly (yaw rate and acceleration sensor) is detected 7 times or more. Malfunction Time 0.5 seconds or more Other 1-trip detection logic Diagnosis Condition The ignition switch is ON. Malfunction Status With the vehicle stopped, the difference between GL1 and GL2 does not become less than 0.4 G within 60 seconds after exceeding 0.6 G. Malfunction Time 0.5 seconds or more Other 1-trip detection logic Diagnosis Condition The ignition switch is ON. Malfunction Status A airbag sensor assembly (yaw rate and acceleration sensor) power source voltage malfunction signal is received for 10 seconds or more with the vehicle speed at 3 km/h (1.8 mph) or more.
