Audible Warning Device Control Module: Description and Operation

The Ram Truck utilizes a [1][2]Central Timer Module ([1][2]CTM). This system is available in a Base or High line configuration. The Base (IEM) configuration does not communicate on the CCD bus and will not be addressed. The CTM will handle most of the electronic timing and chime functions for the systems on the truck. For example: the halo lamp around the key cylinder is timed out after 30 seconds. This is a typical CTM function. The High line CTM provides the following features:
- Remote Keyless Entry (RKE)
- Chime
- Courtesy Lamp controls/Illuminated Entry
- Power Door Locks
- Speed Sensitive Intermittent Wipers
- Enhanced Accident Response
- Vehicle Theft Security System (VTSS)

The [1][2]CTM is located on the right side of the steering column behind the kneeblocker on a metal bracket welded to the instrument panel. It contains a white 8-way and a green 14-way connector.

For additional information on the [1][2]Central Timer Module, refer to Powertrain Management / Computers and Control Systems / Body Control Module. Description and Operation
