Repair Instructions

1. EPB Warning Light Activation / System Malfunction

Step 1: Use the OBD-II scanner to retrieve DTCs. If codes indicate a specific fault, address that issue (e.g., replace a faulty sensor).

Step 3: If the switch works, check the EPB motor by applying direct power to it to see if it engages the caliper.

3. Unusual Noises During Operation

Step 1: Remove the rear wheel and inspect the EPB mechanism and motor. Look for signs of wear or debris.
Step 2: Clean the mechanism and lubricate if necessary.
Step 3: Replace any worn components (e.g., EPB motor) based on inspection.

4. EPB System Malfunction Messages

Step 1: Disconnect the vehicle battery for 10 minutes to reset the EPB system.
Step 2: Reconnect and check if the messages reappear after normal operation.
Step 3: If messages persist, further diagnostics may be required, potentially involving the ABS module.

5. Brake Drag or Poor Performance

Step 1: Check for proper adjustment of the EPB. Follow the manufacturer’s specifications for any necessary adjustments.
Step 2: Inspect the brake pads and rotors for wear and replace if they are beyond specifications.
Step 3: Test drive the vehicle to ensure the issue has been resolved.
