Multi-Axis Acceleration Sensor Module Programming and Setup

Multi-Axis Acceleration Sensor Module Programming and Setup

Note: The Multi-axis Acceleration Sensor is also known as the Inertia Sensor Module (IMU) in SPS. The sensor must be configured using SPS before the vehicle yaw sensor learn is performed.

The multi-axis acceleration sensor module must be programmed with the proper calibration software. The module stores and utilizes this information however if it is not properly configured with the correct calibration software, the multi-axis acceleration sensor module will not control all of the vehicle features properly.

Ensure that the following conditions exist in order to prepare for multi-axis acceleration sensor module programming:

1. The battery is fully charged.
2. The MDI data link connectors are secure.
3. The scan tool is loaded with the most current software version.
4. All disconnected modules and devices are reconnected securely.
5. This entire procedure has been reviewed before proceeding.

Do not reprogram the multi-axis acceleration sensor module unless directed by a service procedure or a service bulletin.

Multi-Axis Acceleration Sensor Module Programming

To program and setup an existing or new replacement multi-axis acceleration sensor module, perform the following procedure:

1. With a scan tool, access the Service Programming System (SPS) and follow the on-screen instructions. Refer to Service Programming System (SPS) (Service Programming System (SPS)).
2. On the SPS Supported Controllers screen, select IMU Inertia Sensor Module - Configuration and follow the on-screen instructions.
3. With a scan tool, clear all DTC's from all modules.
4. Calibrate the yaw sensor using the scan tool. Refer to Vehicle Yaw Sensor Learn (Vehicle Yaw Sensor Learn).

If the multi-axis acceleration sensor module fails to accept the program, verify all scan tool and multi-axis acceleration sensor module connections are secure.

Note: After programming is completed, perform the following to avoid future misdiagnosis:

1. Turn the ignition OFF for 10 seconds.
2. Open and close the door.
3. Connect the scan tool to the data link connector.
4. Ignition ON, engine OFF.
5. With a scan tool, clear all DTC's from all modules.
