PINPOINT TEST G414281p24: ACTUATOR OUTPUT OPEN CIRCUITG414281t102: CHECK THE ACTUATOR CIRCUIT RESISTANCE
1. Key off. 2.
Electric parking brake module connector 1, CA265 disconnected. 3. Key on, engine off. 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 CA265
No
GO to Pinpoint Test G414281t103.
G414281t103: CHECK THE ACTUATOR SIGNAL CIRCUIT FOR OPEN CIRCUIT
1. EPB actuator connector, CA269 disconnected. 2. Measure the resistance between:
