Immobiliser and Tyre Pressure Monitoring System (TPMS) Control Module
The control module for the immobiliser and TPMS system.
IMU (if fitted)
The Inertial Measurement Unit measures the following:
• Longitudinal acceleration
• Vertical acceleration
• Lateral acceleration
• Pitch rate
• Yaw rate
• Roll rate
From these measurements the IMU calculates the motorcycle's lean angle.
The IMU outputs are used for multiple systems, for example, optimised cornering ABS
(OCABS) and fall detection.
If the IMU is fitted, the fall detection switch will not be fitted.
Injector pulse time
The time during which an injector remains open (i.e. delivering fuel).
