Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to prevent any electrical issues.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdrivers
Replacement brake light switch (if faulty)
Replacement shift interlock solenoid (if faulty)

2. Inspect Brake Light Switch

Locate the brake light switch, typically mounted above the brake pedal.
Disconnect the electrical connector from the brake light switch.
Use a multimeter to test the switch for continuity when the brake pedal is pressed.
If the switch shows no continuity, replace it with a new one following the manufacturer’s specifications.

3. Check Transmission Range Sensor

Locate the transmission range sensor on the transmission assembly.
Disconnect the electrical connector and inspect it for corrosion or damage.
Test the sensor with a multimeter according to the service manual specifications.
Replace the sensor if it fails the continuity test or shows incorrect readings.

4. Inspect Shift Interlock Solenoid

Remove the center console cover to access the shift interlock solenoid.
Inspect the solenoid for any signs of wear or damage.
Test the solenoid by applying direct power to it; it should click or engage.
Replace the solenoid if it does not operate correctly.

5. Reassemble and Test

Reconnect all electrical connectors and reassemble any panels removed.
Reconnect the negative battery terminal.
Start the vehicle and test the gear shift operation.
