Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check Brake Pedal Switch

Locate the brake pedal switch, typically mounted above the brake pedal.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity when the brake pedal is pressed.
If faulty, replace the brake pedal switch.

3. Inspect Gear Shifter Linkage

Remove the center console to access the gear shifter assembly.
Visually inspect the linkage for any signs of wear or disconnection.
If loose or damaged, reattach or replace the linkage as necessary.

4. Transmission Fluid Check

Locate the transmission dipstick, remove it, and wipe it clean.
Reinsert the dipstick and pull it out again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid (e.g., Mercon LV).
Check the fluid for burning smell or contamination; if needed, perform a fluid change.

5. Electrical System Check

Inspect relevant fuses in the fuse box for the transmission and brake system.
Replace any blown fuses with ones of the same amperage.
Reconnect the battery and test the brake lights and shifter operation.

6. Final Assembly

Reassemble the center console, ensuring all components are secured.
Reconnect the battery after all work is completed.
