Locate the brake light switch (usually near the brake pedal).
Use a multimeter to test the switch for continuity when the brake pedal is depressed.
If faulty, replace the brake light switch and re-test.

4. Check the Transmission Range Sensor

Tools Required: Socket set, multimeter
Disconnect the wiring harness from the transmission range sensor.
Test the sensor for proper resistance values as per the manufacturer's specifications.
If defective, replace the transmission range sensor with a new one.

5. Examine the Shift Cable
