Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Check Brake Fluid Level

Locate the master cylinder reservoir.
Remove the cap and check the fluid level; if low, top up with the manufacturer-recommended brake fluid.
Reconnect the cap securely.

3. Inspect Brake Light Switch

Locate the brake light switch, usually mounted above the brake pedal.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity when the brake pedal is pressed; replace the switch if defective.

4. Test Shifter Interlock Solenoid

Locate the shifter assembly and the interlock solenoid.
Disconnect the wiring harness from the solenoid.
Use a multimeter to check for voltage at the connector when the brake pedal is pressed; replace the solenoid if no voltage is present.

5. Check for Fault Codes

Reconnect the battery.
Use an OBD-II scanner to check for any stored error codes related to the transmission or shifter.
Address any error codes found, which may include clearing them after repairs.
