General Information - Diagnostic Trouble Code (DTC) Index DTC: Electric
Parking Brake (PBM)
Description and Operation

Electric Parking Brake (PBM)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion


If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals


Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system


Check DDW for open campaigns. Refer to the corresponding bulletins and SSM's which may be valid for the specific
customer complaint and carry out the recommendations as needed.

The table below lists all diagnostic trouble codes (DTCs) that could be logged in the electric parking brake module, for
additional diagnosis and testing information refer to the relevant diagnosis and testing section.
For additional information, refer to: Parking Brake (206-05 Parking Brake and Actuation, Diagnosis and Testing).
