Vehicle Yaw Sensor Learn
WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The Multi-axis Acceleration Sensor is also known as the Inertia Sensor Module (IMU) in SPS and the Yaw Rate Sensor in the scan tool. The sensor must be configured using SPS before the vehicle yaw sensor learn is performed.
The multi-axis acceleration sensor requires a SPS configuration and a yaw rate sensor learn. This is required after certain service procedures are performed. Some of these procedures are as follows:
- Electronic brake control module (EBCM) replacement
- Multi-axis acceleration sensor replacement
- Vehicle yaw sensor replacement
- Vehicle yaw sensor with lateral and longitudinal accelerometer sensor replacement
The yaw rate sensor learn procedure can be completed with a scan tool using the following steps:
- Place vehicle on a level surface.
- Apply the parking brake, or set the transmission in the P position.
- Install the scan tool to the data link connector.
- Ignition ON, engine OFF
- Select Yaw Rate Sensor Reset in the Multi-axis Acceleration Sensor Module Configuration/Reset Functions list.
- Follow the scan tool directions to complete the calibration procedure.
- Select Yaw Rate Sensor Learn in the Multi-axis Acceleration Sensor Module Configuration/Reset Functions list.
- Follow the scan tool directions to complete the calibration procedure.
- Select Yaw Rate Sensor Learn in the EBCM Configuration/Reset Functions list.
- Follow the scan tool directions to complete the calibration procedure.
- Clear any DTCs that may be set.
