WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
The gear position indicator is integrated with the Transmission Control Module as one unit.
The gear position indicator informs the Transmission Control Module on the gear selected, and whether reverse gear is engaged to light the reversing lamp. The gear position indicator contains a permanent magnet and a linear Hall sensor. The gear position indicator creates a signal voltage of between 0 and 5 V which equates to current gear selector lever position.
The gear position indicator can be diagnosed.
