PINPOINT TEST G542812p12: PRIMARY RELEASE SWITCH CIRCUIT SHORT CIRCUIT TO GROUND

G542812t47: CHECK THE PRIMARY RELEASE SIGNAL CIRCUIT FOR SHORT CIRCUIT TO GROUND

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 greater than 100 Kohms?

-> 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
