Inspect the hand brake switch: The hand brake switch might be faulty or misaligned. Locate the switch, which is usually near the hand brake lever or pedal, and visually inspect it for any damage or misalignment.
Test the hand brake switch: To test the hand brake switch, disconnect the electrical connector from the switch and use a multimeter to check the continuity across the switch contacts. When the hand brake is engaged, there should be continuity, and when it's released, there should be an open circuit.
Check the wiring: There may be a problem with the wiring connecting the hand brake switch to the instrument cluster or brake light circuit. Visually inspect the wires for any breaks, shorts, or loose connections.
