CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P1585

DTC Code	DTC Name
P1585	Acceleration Sensor Circuit

DESCRIPTION

The ECM determines the vehicle inclination based on a signal from the yaw rate and acceleration sensor (airbag sensor assembly). If a malfunction in the yaw rate and acceleration sensor (airbag sensor assembly) is determined based on a malfunction signal from the skid control ECU (brake actuator assembly), the ECM stores this DTC.

Tip:

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


DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory
P1585	Acceleration Sensor Circuit	1. Diagnosis Condition 2. Malfunction Status 3. Malfunction Time 4. Other DTC Detection Condition 1: The ignition switch is ON. The output value of the yaw rate and acceleration sensor (airbag sensor assembly) remains at -1.5 G or less, or 1.5 G or more for at least 1.2 seconds. 0.5 seconds or more 1-trip detection logic DTC Detection Condition 2: The ignition switch is ON. The power source voltage to the yaw rate and acceleration sensor (airbag sensor assembly) remains at 4.4 V or less, or 5.6 V or higher for 1.2 seconds or more. 0.5 seconds or more 1-trip detection logic DTC Detection Condition 3: The ignition switch is ON. No signal from the yaw rate and acceleration sensor (airbag sensor assembly) is detected 7 times or more. 0.5 seconds or more 1-trip detection logic DTC Detection Condition 4: The ignition switch is ON. 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. 0.5 seconds or more 1-trip detection logic DTC Detection Condition 5: The ignition switch is ON. A yaw rate and acceleration sensor (airbag sensor assembly) 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. 0.5 seconds or more 1-trip detection logic	Yaw rate and acceleration sensor (airbag sensor assembly) Skid control ECU (Brake actuator assembly) CAN communication system	Does not come on	DTC stored
