Pinpoint Test G542812p21: Apply and Release Switch Contacts Energized Simultaneously

PINPOINT TEST G542812p21: APPLY AND RELEASE SWITCH CONTACTS ENERGIZED SIMULTANEOUSLY

G542812t93: CHECK THE PRIMARY EPB APPLY AND RELEASE CIRCUIT FOR SHORT CIRCUIT FAULTS

1. Key off. 2.





Electric parking brake module connector 1, CA265 disconnected. 3.





Electric parking brake module connector 2, CA266 disconnected. 4. Make sure the parking brake switch is not in the apply or release position. 5. Measure the resistance between:





^ Is the resistance between 1.19 Kohms - 1.222 Kohms?

-> Yes
GO to Pinpoint Test G542812t94.

-> No
GO to Pinpoint Test G542812t95.

G542812t94: CHECK THE SECONDARY EPB APPLY AND RELEASE CIRCUIT FOR SHORT CIRCUIT FAULTS

1. Make sure the parking brake switch is not in the apply or release position. 2. Measure the resistance between:





^ Is the resistance between 1.19 Kohms - 1.222 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 - EPB module connector CA266

-> No
GO to Pinpoint Test G542812t96.

G542812t95: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE SWITCH

1.





Electric parking brake switch, CA243 connector disconnected. 2. Measure the resistance between:





^ Is the resistance greater than 100 Kohms?

-> Yes
INSTALL a new EPB switch.

-> No
REPAIR the short circuit. For additional information, refer to the wiring diagrams.

G542812t96: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE SWITCH

1.





Electric parking brake switch connector, CA243 disconnected. 2. Measure the resistance between:





^ Is the resistance greater than 100 Kohms?

-> Yes
INSTALL a new EPB switch.

-> No
REPAIR the short circuit. For additional information, refer to the wiring diagrams.
