Overhead Travel Information System (OTIS)

WARNING: This page is about a different car, the 1995 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.

The OTIS provides vehicle operator with supplementary information on a Vacuum Fluorescent Display (VFD). The OTIS is located in overhead console. Vehicle operator selects and resets display functions through the use of 4 buttons (US/M, STEP, C/T and RESET). The OTIS obtains most of the information from the CCD bus.

The OTIS powers up when it senses vehicle (battery) voltage on the ignition input circuit. The OTIS blanks the display, then illuminates all segments of the VFD. During this time, the OTIS sends and receives information over CCD bus to determine what to display after its 2 second initialization. The OTIS displays dashes (- -) for any of the screens for which it did not receive bus messages during the 2 second initialization. Dashes will be replaced by valid information if and when it is received.
