Pinpoint Test G531320p24: Actuator Output Open Circuit
PINPOINT TEST G531320p24: ACTUATOR OUTPUT OPEN CIRCUITG531320t102: CHECK THE ACTUATOR CIRCUIT RESISTANCE
1. Key off.
2. Electric parking brake module connector 1 (CR50) disconnected.
3. Key on, engine off. Make sure the brake pedal is not pressed.
4. Measure the resistance between:
^ Is the resistance between 0.5 ohms - 1 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 module connector, CR50
-> No GO to Pinpoint Test G531320t103.
G531320t103: CHECK THE ACTUATOR SIGNAL CIRCUIT FOR OPEN CIRCUIT
1. EPB actuator disconnected
2. Measure the resistance between:
^ Is the resistance less than 10 ohms?
-> Yes GO to Pinpoint Test G531320t104.
-> No REPAIR the open circuit. For additional information, refer to Vehicle/Diagrams.
G531320t104: CHECK THE ACTUATOR RETURN CIRCUIT FOR OPEN CIRCUIT
1. Measure the resistance between:
^ Is the resistance less than 10 ohms?
-> Yes GO to Pinpoint Test G531320t105.
-> No REPAIR the open circuit. For additional information, refer to Vehicle/Diagrams.
G531320t105: CHECK THE ACTUATOR CIRCUIT RESISTANCE
1. Measure the resistance between:
^ Is the resistance between 0.5 ohms - 1 ohm?
-> Yes REPAIR the open circuit. For additional information, refer to Vehicle/Diagrams.
-> No INSTALL a new EPB actuator.
