Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Brake Light Switch

Locate the brake light switch, typically near the top of the brake pedal.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity when the brake pedal is pressed.
- If no continuity, replace the brake light switch.
- If functional, reconnect the wiring harness.

3. Test Shift Interlock Solenoid

Locate the shift interlock solenoid, usually near the shifter assembly.
Disconnect the electrical connector from the solenoid.
Use a multimeter to check for voltage when the brake pedal is pressed.
- If there is no voltage, trace wiring for issues or replace the solenoid.
- If voltage is present, proceed to reinstall the solenoid.

4. Inspect Shift Cable

Remove the shifter trim cover to access the shift cable.
Check for any signs of fraying or damage on the shift cable.
If damaged, remove the cable from the shifter and transmission, and replace it with a new one.

5. Reassemble and Reconnect

Reconnect all components in reverse order of disassembly.
Reconnect the negative battery terminal.
Ensure that everything is secured and properly installed.
