Where is the CTM on a 2005 Dodge Dakota?
There isn’t a standalone Central Timing Module (CTM) in a 2005 Dodge Dakota. The vehicle relies on the PCM (Powertrain Control Module) for engine timing and fuel management, and the BCM (Body Control Module) for non-engine electrical functions.
In more detail, the term CTM appears in some dealer notes or owner discussions but is not used as a separate, serviceable module in official Dodge documentation for this truck. When diagnosing timing or electronic control issues on a 2005 Dakota, you’re typically dealing with the PCM and BCM, not a distinct CTM. Below are the main modules you’re likely to encounter and where they’re usually located.
CTM terminology and Dakota hardware
The Central Timing Module (CTM) label is not part of the standard Dakota wiring layout. The truck’s timing and electronic control responsibilities are split mainly between the PCM and the BCM. The following sections identify these two core modules and their typical locations.
These are the two main modules most people are trying to locate when diagnosing timing or electronics issues on a 2005 Dakota.
- Powertrain Control Module (PCM) — located in the engine bay, usually on the driver’s side near the firewall or inner fender. It’s the primary ECU that oversees engine timing, fuel delivery, and emissions controls.
- Body Control Module (BCM) — located under the dash on the passenger side or behind the glove box/kick panel area, depending on trim. It manages non-engine electrical systems such as lighting, door locks, and instrument communications.
These are not labeled as CTM in typical service materials, but they perform the timing and control functions that some owners might attribute to a “CTM.” If you see a CTM reference in diagnostic notes, prepare to investigate PCM or BCM faults rather than a separate CTM unit.
Where to look on your Dakota
To physically locate these modules on your specific 2005 Dakota, you’ll generally search the engine bay for the PCM and inspect the under-dash area for the BCM. The following sections outline practical steps to identify each module on most Dakotas of this era.
Locating the Powertrain Control Module (PCM)
In many 2005 Dakotas, the PCM sits in the engine compartment on the driver’s side near the firewall or inner fender. It’s a rectangular unit with a large multi-pin connector. You may need to remove some ducting or a cover to access it safely.
Locating the Body Control Module (BCM)
The BCM is typically mounted under the instrument panel on the passenger side or behind the glove box, depending on the exact trim and market. Access usually requires removing the glove box or nearby trim panels to reach the connector bundle.
Accessing and safety tips
Always disconnect the negative battery cable before touching electrical modules. When removing panels, label screws and connectors to ease reassembly. If you’re diagnosing a CTM-like symptom, start with a reputable OBD-II scan to read PCM/BCM codes and consult the factory service manual or dealer for the wiring diagram specific to your VIN and engine variant.
Note that there can be slight variations by trim level or production region. If you cannot locate the PCM or BCM using these guidelines, refer to the official Dodge service manual for your exact configuration or consult a certified technician.
Summary
For the 2005 Dodge Dakota, there is no distinct Central Timing Module (CTM) as a separate component in the standard wiring diagrams. Timing and related control functions are handled by the PCM (engine timing and management) and the BCM (body/electrical systems). Knowing where the PCM (engine bay, driver’s side) and BCM (under-dash on the passenger side or behind the glove box) sit will help you diagnose timing or electrical issues more effectively and determine if a module replacement is necessary.
