Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if it has been recently operated.

2. Inspect Wiring and Connections

Sub-steps:
1. Locate the brake control module, usually found near the master cylinder.
2. Visually inspect the wiring harness for frays or breaks.
3. Disconnect the harness and check for corrosion on the connectors.
4. Clean any corrosion using electrical contact cleaner and a soft brush.

3. Test Brake Control Module

Sub-steps:
1. Reconnect the wiring harness to the brake control module.
2. Use a multimeter to check voltage at the brake control module connector.
  - Expected voltage should be around 12V with the ignition on.
3. If voltage is absent, trace the wiring back to the ECU to identify breaks or shorts.

4. Replace Brake Control Module (if necessary)

Sub-steps:
1. Remove the brake control module by unscrewing it from its mounting bracket.
2. Disconnect the electrical connectors and remove the module.
3. Install the new brake control module by reversing the removal steps.
4. Torque the mounting screws to the manufacturer’s specifications.

5. Reconnect Battery and Perform System Reset

Sub-steps:
1. Reconnect the vehicle’s battery terminals.
2. Use a diagnostic scanner to clear any stored codes and reset the system.
3. Conduct a road test to ensure proper functionality and that the C1201 code does not return.
