    CR32 connector, harness side EPB actuator connector, harness side
    Electric parking brake actuator - signal - Pin 10 Electric parking brake actuator - signal - Pin 04
    • Is the resistance less than 10 ohms? 
    • Yes:  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.
