Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, and flashlight.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Inspect Brake Pedal Switch

Locate the brake pedal switch, which is usually mounted above the brake pedal.
Sub-steps:
1. Disconnect the electrical connector from the brake pedal switch.
2. Use a multimeter to test for continuity when the brake pedal is pressed.
3. If there is no continuity, replace the brake pedal switch.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Sub-steps:
1. Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
2. If the level is low, top off with the recommended brake fluid (usually DOT 3 or DOT 4).
3. Inspect for any leaks in the brake lines or connections.

4. Verify Shift Interlock System

Inspect the shift interlock solenoid and its wiring.
Sub-steps:
1. Disconnect the wiring harness from the shift interlock solenoid.
2. Use a multimeter to check for power at the connector when the brake pedal is pressed.
3. If no power is present, trace the wiring back to the brake switch and fuse.

5. Check Transmission Fluid

Locate the transmission dipstick and check the fluid level and condition.
Sub-steps:
1. Remove the dipstick, wipe it clean, and reinsert it to check the level.
2. If the fluid is low, add the manufacturer-recommended transmission fluid.
3. If the fluid is dark or has a burnt smell, consider a transmission fluid change.

6. Inspect Shift Linkage

Check for any visible obstructions or damage to the shift linkage.
Sub-steps:
1. Inspect the linkage from the gear lever to the transmission.
2. Ensure all connections are secure and adjust if necessary.
3. If damaged, replace the shift linkage components.
