Solution

1. Preparation

Ensure the vehicle is in a safe area and on level ground.
Disconnect the negative battery terminal to prevent electrical issues while working.
Gather tools: OBD-II scanner, socket set, fluid pump (if checking fluid), and multimeter.

2. Inspect Gear Shift Mechanism

Remove the center console cover to access the gear shift assembly.
Check for any obstructions or foreign objects around the gear shift lever.
If needed, remove the gear shift assembly from the vehicle for further inspection.

3. Check Brake Pedal Switch

Locate the brake pedal switch, typically found near the top of the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If the switch is faulty, replace it with a new one following the manufacturer's specifications.

4. Transmission Fluid Check

Remove the transmission fluid dipstick (if applicable) or access the transmission pan.
Use a fluid pump to extract a small amount of fluid for inspection.
Check the fluid color and smell; it should be a clear red and not burnt. If contaminated, perform a fluid change.
Refill the transmission fluid to the manufacturer’s specified level using the recommended fluid type.

5. Reassemble and Test

Reattach the gear shift assembly and center console cover.
Reconnect the negative battery terminal.
Start the vehicle and attempt to engage reverse gear to check for functionality.
