Performing a soft reset on your vehicle's electrical system can help resolve minor issues by restarting the vehicle's electronics and clearing temporary glitches. Here’s how to perform a soft reset:
Steps to Perform a Soft Reset
-
Initial Reset Procedure
- Get in Your Vehicle: Sit in the driver’s seat.
- Insert the Key: Put the key in the ignition.
- Set to Run Mode: Turn the key to the run mode (just short of cranking the vehicle) and hold for 12 seconds. Use a stopwatch for precision.
- Turn Off the Vehicle: Turn the key to the off position.

Battery Disconnect Method
- Ensure Safety: Park your vehicle on a flat surface and engage the parking brake. Ensure the engine is turned off.
- Disconnect the Battery: Open the vehicle’s hood and locate the battery. Use a wrench or socket to disconnect the negative (black) terminal of the battery. Loosen the nut and remove the cable from the terminal. This will disconnect the power from the vehicle’s electrical system.
- Wait: Allow the vehicle to sit without power for about 10-15 minutes to discharge completely and reset the vehicle’s electronic modules.
- Reconnect the Battery: Reattach the negative (black) cable to the battery terminal and tighten the nut securely.
- Restart the Vehicle: Start the vehicle’s engine and allow it to idle for a few minutes to give the vehicle’s electronic systems time to recalibrate and reset.
- Check for Issues: Verify the functionality of the vehicle’s electronic components and systems, including lights, dashboard indicators, radio, and other electrical features.
