An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other

physical damage to the harness. If no fault is found in the circuit, suspect the following

component(s): - EPB module - EPB actuator - EPB module connector, CR50 - EPB module connector,

CR32 - EPB actuator connector

-> No

REPAIR the open circuit. For additional information, refer to the wiring diagrams.
