Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

Tools Required:

Socket set
Multimeter
Screwdriver set
Pliers

2. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the fluid is at the appropriate level (between the minimum and maximum markings).
If low, top off with recommended brake fluid (DOT 3 or DOT 4).

3. Inspect Brake Light Switch

Locate the brake light switch, typically mounted near the brake pedal.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity when the brake pedal is pressed.
If no continuity is detected, replace the brake light switch.

4. Test Shift Interlock Solenoid

Locate the shift interlock solenoid, which is generally found near the gear shift assembly.
Disconnect the wiring harness from the solenoid.
Use a multimeter to check for voltage at the connector when the brake pedal is pressed.
If voltage is present but the solenoid does not engage, replace the solenoid.

5. Reassemble and Reconnect

Reconnect all wiring harnesses and components previously disconnected.
Reconnect the negative battery terminal.
Ensure all components are securely fastened.
