Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdrivers, flashlight.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts.

2. Inspect Brake Light Circuit

Reconnect the battery.
Check the brake lights by pressing the brake pedal. If the lights do not illuminate, replace any burnt-out bulbs.
If the brake lights work, proceed to test the brake pedal switch for continuity using a multimeter.

3. Test Shift Interlock Solenoid

Locate the shift interlock solenoid (typically found near the gear shift assembly).
Disconnect the electrical connector and use a multimeter to check for power (should be around 12V) and ground while the brake pedal is pressed.
If the solenoid does not receive power, trace the wiring back to the brake switch or fuse.

4. Inspect Gear Shift Linkage

Remove any trim covers around the gear shift lever to access the linkage.
Check for any physical damage or disconnection in the linkage.
Manually shift the linkage to confirm it moves freely and engages the transmission.

5. Check Transmission Fluid

Locate the transmission dipstick (if equipped).
Remove the dipstick, clean it, and reinsert it, then check the fluid level.
If low, add the appropriate transmission fluid (consult the owner's manual for specifications).
