A Guide to Resetting the Jeep 4xe Charging System

Owning a Jeep 4xe is an exciting venture into the world of plug-in hybrid technology, offering the best of both gasoline and electric power. However, like any vehicle, there may be instances where you encounter issues with the charging system.

One common problem is the “Service Charging System” error message. In this article, we’ll explore the steps to reset the Jeep 4xe charging system and address common concerns associated with this error.

Understanding the “Service Charging System” Error

The “Service Charging System” error can be a source of frustration, especially for new Jeep 4xe owners. This message may appear on your dashboard, signaling potential charging issues.

While it’s essential to address this promptly, there are steps you can take before heading to the dealership.

Check for Additional Messages: Before attempting a reset, check if there are any additional error messages or warnings. Understanding the full context of the issue can provide valuable information and help you communicate effectively with your dealer.

Inspect Charging Equipment: Ensure that your charging equipment, whether it’s a WallBox Level 2 Charger or the L1 charger that came with your Jeep, is functioning correctly. Some users have reported issues related to charging amps, so it’s worth verifying your settings.

Resetting the Jeep 4xe Charging System

If you’ve ruled out simple equipment issues and want to try resetting the charging system on your own, follow these steps:

Manual Reset: Start by manually resetting the vehicle’s systems. Turn off the Jeep, open the hood, and locate the negative terminal on the battery. Disconnect the negative terminal for a few minutes, then reconnect it. This process can help reset various electronic systems, including the charging module.

Use an Aftermarket Tuner or Code Reader: Some users have successfully reset the charging system using aftermarket tuners or code readers. If you have access to such tools, they might provide an alternative solution. However, be cautious and follow the instructions provided by the tuner or code reader manufacturer.

Adjust Charging Amps: If you have a WallBox or similar charging equipment, check the charging amps settings. The Jeep 4xe has a maximum charging capacity of 32 amps. If your equipment allows for settings beyond this limit, adjusting it to a maximum of 32 amps may help prevent charging system errors.
