1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and a flathead screwdriver.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

Remove the radio unit from the dashboard using appropriate tools (flathead screwdriver may be needed for trim removal).
Inspect the power connector for any signs of wear, damage, or loose connections.
If damaged, repair or replace the wiring harness as necessary.

With the radio unit still accessed, hold the power button for 10 seconds to perform a hard reset.
Alternatively, reconnect the negative battery terminal, wait for a few minutes, then reconnect it to reset the system.
