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).
For further information, also see Signal specifications.

Signals
The table below summarizes the input signals to and output signals from the Park Brake Module (PBM). The signal types are divided into directly connected signals and CAN communication. The illustration below displays the same information with the Volvo component designations.
