Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Inclination sensor module (ISM)
The inclination sensor module (ISM) is on the left-hand side of the rear relay box.
The inclination sensor module (ISM) is powered from the rear electronic module (REM), which both activates and deactivates it. Information is transferred from the inclination sensor module (ISM) to the rear electronic module (REM) using serial communication.
The inclination sensor module (ISM) detects when the angle of the car changes. If the angle changes when the car is alarmed, a signal is transmitted to the rear electronic module (REM) which sends this data out on the controller area network (CAN) to activate the alarm.
There are diagnostics for the Inclination Sensor Module (ISM).
