Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid pump, multimeter.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for safety.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick or access port (if applicable).
Remove the dipstick and wipe it clean with a lint-free cloth.
Reinsert the dipstick and remove it again to check the fluid level against the markers.
If low, use a fluid pump to add the correct type of transmission fluid (refer to the owner's manual for specifications).
Inspect fluid condition; if it’s dark or has a burnt smell, proceed with a fluid change.

3. Inspect and Repair Linkage

Locate the transmission linkage under the vehicle.
Visually inspect for any disconnections or damage.
If damage is found, replace the linkage using a socket set to remove the old component.
Reattach the new linkage, ensuring it is secured tightly to avoid future issues.

4. Check the Brake Switch

Locate the brake switch near the brake pedal.
Use a multimeter to test the switch continuity when the pedal is pressed.
If the switch is faulty, disconnect the power and replace with a new brake switch.

5. Verify Battery Voltage

Use a multimeter to check the battery voltage; it should be around 12.6 volts.
If low, charge or replace the battery as necessary.
Ensure all connections are clean and tight to avoid electrical issues.
