Welcome to JustAnswer!!! My name is Brad, I will be helping you with your question today...

I'm a 15 Yr Dodge Dealership technician, and it sounds liek the CTM Central Timer Module is faulty.. It's located here:

In the drivers side kickpanel.. I would disconnect it and reconnect it.. IF everything works replace the CTM... It controls this:

The Central Timer Module (CTM) monitors many hard wired switch and sensor inputs as well as those resources it shares with other modules in the vehicle through its communication over the Programmable Communications Interface (PCI) data bus network. The programming and all of the inputs allow the CTM to determine the tasks it needs to perform and their priorities, as well as both the standard and optional features that it should provide. The CTM then performs those tasks and provides those features through both PCI data bus communication with other modules and through hard wired outputs through a number of driver circuits, relays, and actuators. These outputs allow the CTM the ability to control numerous accessory systems.

The CTM operates on battery voltage received through two fuses in the Junction Block (JB) on two non-switched fused B(+) circuits, a fused ignition switch output (run-start) circuit, and a fused ignition switch output (run-acc) circuit. This arrangement allows the CTM to provide some features regardless of the ignition switch position. The CTM is grounded to the chassis. Two of these ground circuits are on the left inner cowl panel near the CTM, while the third is near the Airbag Control Module (ACM).

The CTM monitors its own internal circuitry as well as many of its input and output circuits, and will store Diagnostic Trouble Codes (DTC) in memory for any failure it detects. These DTCs can be retrieved and diagnosed using a DRBIII® scan tool. Refer to the appropriate diagnostic information.


The hard wired inputs to the CTM include the following:

  • Cargo lamp switch sense
  • Courtesy lamp switch sense
  • Cylinder lock switch sense - high line with VTSS only
  • Driver door ajar switch sense
  • Driver door switch mux - high line with power locks only
  • Fog lamp switch sense
  • Front washer pump/motor control
  • Front wiper park switch sense
  • Fused B(+) (two circuits)
  • Fused ignition switch output (run-acc)
  • Fused ignition switch output (run-start)
  • Ground (three circuits)
  • Headlamp switch off sense
  • High beam switch output
  • Interior lamp defeat
  • Intermittent front wiper mode sense
  • Intermittent front wiper switch signal
  • Key-in ignition switch sense
  • Low beam switch output
  • Park brake switch sense
  • Park lamp switch sense
  • Passenger door ajar switch sense
  • Passenger door switch mux - high line with power locks only
  • PCI bus circuit
  • Radio control mux - high-line with remote radio switches only
  • Washer switch sense
  • Wiper park switch sense
  • Wiper switch mode sense
  • Wiper switch mode signal


The hard wired outputs of the CTM include the following:

  • Cargo lamp driver
  • Courtesy lamp driver
  • Door lock relay output - high-line with power locks only
  • Door unlock relay output - high-line with power locks only
  • Driver door unlock relay output
  • Fog lamp relay control - with fog lamps only
  • Front washer pump/motor control
  • Front wiper park switch sense
  • Front wiper relay control
  • Glove box lamp driver
  • High beam indicator driver
  • Horn relay control - high-line with power locks only
  • Interior lamp driver
  • Left high beam driver
  • Left low beam driver
  • Park lamp relay control
  • Right high beam driver
  • Right low beam driver
  • VTSS indicator driver - high-line with VTSS only


I hope this helps!!!!
