Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety while working on the electrical systems.
Tools required: OBD-II scanner, multimeter, socket set, torque wrench.

2. Inspect and Repair Wiring

Remove the center console cover to access the parking brake switch.
Inspect the wiring harness for any frayed or broken wires; repair or replace as necessary.
Ensure all connectors are firmly seated.

3. Check and Replace Actuator

If the actuator is faulty, locate it at the rear brake assembly.
Remove any components blocking access to the actuator.
Disconnect the actuator's electrical connector.
Unbolt the actuator from the assembly using the appropriate socket size.
Install the new actuator by reversing the removal steps and ensuring it is properly torqued to specifications (typically around 20-30 Nm).

4. Reassemble Components

Reconnect any components removed during the actuator replacement.
Reinstall the center console cover.
Reconnect the vehicle's battery.

5. Reset the System

Use the OBD-II scanner to clear any error codes from the parking brake system.
