Diagnostic Steps

1
Check the brake pedal switch for proper operation.
2
Inspect the brake light fuse for continuity.
3
Verify that the gear selector is properly aligned and not obstructed.
4
Test the shift interlock solenoid for functionality.
5
Scan for error codes using an OBD-II scanner to identify any transmission-related issues.

Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is on a flat surface and the parking brake is applied.

2. Inspect Brake Pedal Switch

Locate the brake pedal switch, usually found above the brake pedal.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity when the pedal is pressed.
- If no continuity, replace the brake pedal switch.
- If continuity exists, reconnect the switch.

3. Check Brake Light Fuse

Access the fuse box, typically located under the dashboard or in the engine compartment.
Locate the fuse for the brake lights (refer to the owner’s manual for the specific fuse location).
Remove the fuse and inspect for any signs of damage or burning.
- Replace the fuse if it is blown; otherwise, proceed to the next step.

4. Test Shift Interlock Solenoid

Locate the shift interlock solenoid, usually near the gear shifter assembly.
Disconnect the wiring harness from the solenoid.
Using a multimeter, check for voltage at the connector while pressing the brake pedal.
- If there is no voltage, trace the wiring back to the brake switch and check for any breaks.
- If voltage is present, replace the shift interlock solenoid.

5. Reassemble and Test

Reconnect all components and ensure they are secured properly.
Start the vehicle and attempt to shift out of Park while pressing the brake pedal.
