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 gear position indicator is integrated with the Transmission Control Module (TCM) as one unit.
The gear position indicator informs the Transmission Control Module (TCM) 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 5V which equates to current gear selector lever position.
The gear position indicator can be diagnosed.
