The Dodge Avenger’s Wireless Control Module (WCM) manages key programming and various vehicle functions. Understanding its operation is crucial for successful key programming, WCM replacement, and remote start installation. This article addresses common questions and concerns regarding the Dodge Avenger Wcm.
Key Programming and the Dodge Avenger WCM
Once a key is programmed to a specific Dodge Avenger WCM, it’s permanently linked to that vehicle. This pairing occurs due to a “secret key” exchange between the Powertrain Control Module (PCM) and the WCM during programming. This security measure prevents keys programmed for one vehicle from being used on another.
Replacing the WCM requires a specific procedure. If both the PCM and WCM need replacement, they must be installed sequentially, not simultaneously. First, install the new PCM or WCM and perform the corresponding replacement routine. Then, install the remaining module and repeat the routine. This two-step process allows the “secret key” to be transferred, ensuring proper functionality. Attempting to replace both modules at once will lead to programming failures. Existing keys can be reprogrammed to a new WCM, but it’s recommended to erase old key programming first to ensure a clean slate and avoid potential conflicts.
Dodge Avenger Remote Start Installation and WCM
Adding remote start to a Dodge Avenger often involves installing a new WCM specifically designed for remote start functionality. This kit typically includes two new keys, the remote start-enabled WCM, an antenna, a hood pin safety switch, and the necessary wiring.
While purchasing the complete remote start kit might seem more expensive initially, it can be more cost-effective than sourcing individual components separately. The listed retail price for the kit is around $243, with installed prices varying. Remember that installation time can significantly impact the final cost, as the process involves several steps beyond simply replacing the WCM.
The installation requires expertise and includes tasks like installing the antenna, routing wiring, connecting the hood switch, cutting and programming new keys, and configuring the Totally Integrated Power Module (TIPM). Due to the complexity of the process, dealerships and installers often charge more than the standard book time to adequately compensate for labor.
Conclusion: Working with the Dodge Avenger WCM
Understanding the Dodge Avenger WCM’s intricacies is essential for anyone tackling key programming, module replacement, or remote start installation. The linked nature of keys and the WCM, the sequential replacement procedure, and the complexities of remote start installation all require careful consideration. While DIY might be tempting, professional installation is often recommended to avoid potential complications and ensure proper functionality. Remember to consult official documentation and resources for accurate information and procedures specific to your Dodge Avenger’s model year.
