What does Electronic Chassis Control Module control on 1993 Le baron Convt and what other models will interchange with this unit?

In a 1993 Chrysler LeBaron Convertible, the Electronic Chassis Control Module (ECCM) is a crucial component responsible for managing several aspects of the vehicle's handling and performance. It primarily controls:

* Automatic Transmission Shifting: The ECCM interacts with the transmission control system, influencing shift points and overall transmission behavior. It doesn't directly control the transmission itself, but acts as a significant interface between the engine and the transmission.

* Speed Control (Cruise Control): The ECCM manages the functionality of the cruise control system, maintaining a set speed.

* Vehicle Speed Sensor Input: It receives speed signals from the vehicle speed sensor and uses this information for various functions, including cruise control and transmission control.

* Other Sensor Inputs: It takes inputs from numerous other sensors to refine its control strategies, though the precise sensors can vary. These might include throttle position sensor, coolant temperature sensor, etc.

Interchangeability:

Finding a direct, interchangeable ECCM for a 1993 LeBaron Convertible is challenging. The ECCM's part number is highly specific to the model year, engine type (3.0L or 2.5L), and options (like the presence of specific electronic features). Simply put, there aren't many other Chrysler models that will use the *exact same* part.

To find a suitable replacement, you'll need:

1. The precise part number of your ECCM: This is the most reliable way to identify a compatible replacement. This number is usually found on a sticker on the module itself.

2. Consult a reputable parts supplier: They can use your vehicle's VIN (Vehicle Identification Number) to determine the correct ECCM for your specific LeBaron.

3. Check online parts databases: Sites like RockAuto, AutoZone, or Advance Auto Parts allow you to search for parts using your VIN or other vehicle details. However, double-check the compatibility information they provide.

Important Note: Even if you find a module with a similar part number from another Chrysler vehicle, compatibility isn't guaranteed. The ECCM needs to be programmed (flashed) to match your vehicle's specific configuration, and incorrect programming can cause serious problems. A professional mechanic or specialized shop will be better equipped to deal with this. Don't attempt to simply swap an ECCM without understanding the potential consequences.
