Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to prevent any electrical shorts or shocks.
Gather tools such as a socket set, OBD-II scanner, and a multimeter.

2. Check Transmission Fluid

Locate the transmission dipstick (if applicable) and remove it for inspection.
Wipe the dipstick clean, reinsert it, and then remove it again to check the fluid level.
If the fluid is low, top it off with the manufacturer-recommended transmission fluid (typically ATF Type T-IV for this model).
Inspect the fluid for burnt smell or dark coloration; replace if necessary.

3. Inspect Transmission Linkage

Remove the center console cover to access the shifter assembly.
Check the linkage for any visible damage or disconnections.
Adjust or reconnect the linkage as necessary, ensuring it is securely attached and operating smoothly.

4. Test Brake Switch

Locate the brake switch, usually situated above 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.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and attempt to shift through the gears while monitoring for any issues.
