Actuator Output Short Circuit to Ground
PINPOINT TEST G414281p13: ACTUATOR OUTPUT SHORT CIRCUIT TO GROUNDG414281t49: CHECK THE ACTUATOR NEGATIVE SIGNAL CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Key off. 2.
Electric parking brake switch connector, CA243 disconnected. 3. Key on, engine off. 4. Measure the resistance between:
^ Is the resistance greater than 100 Kohms?
Yes
GO to Pinpoint Test G414281t50.
No
GO to Pinpoint Test G414281t51.
G414281t50: CHECK THE ACTUATOR POSITIVE SIGNAL CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. 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
GO to Pinpoint Test G414281t52.
G414281t51: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE ACTUATOR
1. EPB actuator connector, CA269 disconnected. 2. Measure the resistance between:
^ Is the resistance greater than 100 Kohms?
Yes
INSTALL a new EPB actuator.
Parking Brake Release Actuator
No
REPAIR the short circuit.
G414281t52: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE ACTUATOR
1. EPB actuator connector, CA269 disconnected. 2. Measure the resistance between:
^ Is the resistance greater than 100 Kohms?
Yes
INSTALL a new EPB actuator.
Parking Brake Release Actuator
No
REPAIR the short circuit.
