2008 Jeep Patriot Sport P0700 Code: Transmission Issue After Wireless Control Module Replacement?

Model: 2008 Jeep Patriot Sport Fault Code: P0700 Posted: 2015-07-30 16:54

I recently had the wireless control module replaced on my 2008 Jeep Patriot Sport. After the replacement, the engine light came back on and the diagnostic code displayed is P0700. I'm wondering if this issue is related to the previous repair or if it points to a transmission problem. The dealership replaced the wireless control module and programmed it using an internet-based system—this was required at the time of installation. Now, with the engine light back on and only showing P0700, I’m concerned whether this code originated from the first repair or is actually indicating a deeper issue with the transmission control module (TCM). Could this be a result of improper reprogramming or a separate transmission fault? Any insights would be greatly appreciated.

P0700 is a generic diagnostic code that indicates the transmission control module (TCM) has detected an issue. A scan tool will typically reveal specific transmission-related codes—sometimes the 'key dance' trick may not display them, so using a proper OBD2 scanner is essential. Could you clarify what the wireless control module is? Who replaced it? Was this part related to remote start functionality? I don’t believe remote start was an option on 2008 Jeep Patriot Sport models. Please share more details for better context.

Thanks for the input, Kev2. I’m not very familiar with the wireless control module—my understanding is it relates to starting the vehicle. The dealership replaced it, and the mechanic mentioned that sometimes a key fob component also needs replacement, but in my case, only the module was swapped. Previously, when the engine light came on, it showed this same P0700 code, which required a dealer visit for programming via internet. It’s frustrating to see the issue return after what I thought was a successful fix—sometimes I feel like I’m being overcharged because I don’t fully understand these technical systems.

My suspicion is that this involves a SKIM (Security Key Immobilizer Module) system. This module controls vehicle security and can cause no-start issues or illuminate the security light on the dashboard. The SKIM system often requires dealer programming, and the key fob plays an integral role in its operation. As previously suggested, have your vehicle scanned—this service is typically free at authorized dealerships or repair shops. If only P0700 appears during scanning, it may indicate that the TCM isn’t receiving proper power or signal. This could point to a wiring issue, faulty connection, or failure in the transmission control module itself.

I had the vehicle scanned yesterday and only P0700 was detected. Thanks for all the helpful advice—this has been very informative and reassuring.
