Inclination sensor module (ISM)
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
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).
