Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Control Module
The most important task of the Park Brake Module (PBM) is to manage the functions for the electrically operated parking brake.
Park Brake Module (PBM) is located in the cargo compartment's left side.
Park Brake Module (PBM) communicates both with directly connected components, and with other control modules via CAN communication.
The control module checks activations that are made, and the input and output signals through integrated diagnostics. A diagnostic trouble code (DTC) is stored when the control module detects a fault. Any diagnostic trouble codes (DTC) are stored in the control module memory. The information can be read off using the diagnostic tool.
A simple way to check that the Park Brake Module (PBM) is supplied with voltage is to activate the parking brake and check that the P symbol lights in the Driver information module (DIM).
