The park brake switch (1) is located on the park brake lever mechanism on the floor panel transmission tunnel
below the center floor console. This switch includes a spade-type output terminal (2) that connects the switch to
the vehicle electrical system through a dedicated take out and connector of the body wire harness. The output
terminal is integral to the stationary contact within a molded plastic insulator. A locating tab (4) on the insulator
engages a slot in the park brake lever mechanism for positive switch location. External to the insulator is a
movable leaf contact (3) with an integral grounding lug on one end and an integral actuating lever and follower
on the opposite end. The switch is secured to and grounded by a single screw to the park brake lever
mechanism.

The park brake switch cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.

OPERATION

PARK BRAKE SWITCH

The park brake switch is a normally closed, mechanically actuated leaf contact switch that is operated by the
park brake lever mechanism. The switch is grounded through its mounting to the park brake lever mechanism

and provides a ground input to the Electro Mechanical Instrument Cluster (EMIC) (also known as the Cab
Compartment Node/CCN) on a park brake switch sense circuit whenever the park brake is applied, and opens
this circuit whenever the park brake is released. The park brake switch sense input to the EMIC is used for
control of the brake indicator and may also be used as a logic input for other electronic features in the vehicle.

The park brake switch as well as the hard wired inputs and outputs of the switch may be diagnosed using
conventional diagnostic tools and procedures. Refer to the appropriate wiring information.

DIAGNOSIS AND TESTING

PARK BRAKE SWITCH

INDICATOR ILLUMINATES DURING BULB TEST, BUT DOES NOT WHEN PARK BRAKE APPLIED

1. Disconnect and isolate the battery negative cable. Disconnect the wire harness connector for the park

brake switch from the switch terminal. Apply the parking brake. Check for continuity between the park
brake switch terminal and a good ground. There should be continuity. If OK, go to step 2. If not OK,
replace the ineffective park brake switch.

2. Disconnect the instrument panel wire harness connector from the cluster connector receptacle. Check for

continuity between the park brake switch sense circuit cavities of the wire harness connector for the park
brake switch and the wire harness connector for the instrument cluster. There should be continuity. If not
OK, repair the open park brake switch sense circuit between the park brake switch and the instrument
cluster as required.

INDICATOR REMAINS ILLUMINATED - BRAKE SYSTEM CHECKS OK

1. Disconnect and isolate the battery negative cable. Disconnect the wire harness connector for the park

brake switch from the switch terminal. Check for continuity between the terminal of the park brake
switch and a good ground. There should be no continuity with the park brake released, and continuity
with the park brake applied. If OK, go to step 2. If not OK, replace the ineffective park brake switch.

WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable
the Supplemental Restraint System (SRS) before attempting any steering
wheel, steering column, airbag, Occupant Classification System (OCS),
seat belt tensioner, impact sensor, or instrument panel component
diagnosis or service. Disconnect and isolate the battery negative (ground)
cable, then wait two minutes for the system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to
disable the SRS. Failure to take the proper precautions could result in
accidental airbag deployment.

NOTE:

If the brake indicator stays ON with the ignition switch in the ON position and
the park brake released, or comes ON while driving, the brake system must be
diagnosed and repaired prior to performing the following tests. Refer to
DIAGNOSIS AND TESTING . If no brake system problem is found, the following
procedures will help to locate a shorted or open park brake switch sense
circuit, or an ineffective park brake switch.

2. Disconnect the instrument panel wire harness connector from the cluster connector receptacle. Check for

continuity between the park brake switch sense circuit cavity of the wire harness connector for the park
brake switch and a good ground. There should be no continuity. If not OK, repair the shorted park brake
switch sense circuit between the park brake switch and the instrument cluster as required.

REMOVAL

1. Disconnect and isolate the battery negative cable.

2. Remove the console from the floor panel transmission tunnel. Refer to REMOVAL .

3. Apply the parking brake lever mechanism (3).

4. Disconnect the wire harness connector (2) from the terminal of the park brake switch (1) located on the

left side of the park brake lever mechanism.

5. Remove the screw (4) that secures the park brake switch to the park brake lever mechanism.

6. Remove the switch from the park brake lever mechanism.

WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable
the Supplemental Restraint System (SRS) before attempting any steering
wheel, steering column, airbag, Occupant Classification System (OCS),
seat belt tensioner, impact sensor, or instrument panel component
diagnosis or service. Disconnect and isolate the battery negative (ground)
cable, then wait two minutes for the system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to
disable the SRS. Failure to take the proper precautions could result in
accidental airbag deployment.
