three internal switches as shown (Fig. 24). You
should achieve the results as listed in the figure.
(3) Gently push the plunger on the brake lamp
switch in until it stops.
(4) With the switch in the depressed position
(plunger pushed in), use an ohmmeter to test each of
the three internal switches as shown (Fig. 25). You
should achieve the results as listed in the figure.
If you do not achieve the results as listed in both
figures, the switch is faulty and must be replaced.
(5) Install the switch in the vehicle. Refer to
REMOVAL AND INSTALLATION in this section for
the proper procedure.
SERVICE PROCEDURES
BRAKE FLUID LEVEL CHECK
Check master cylinder reservoir brake fluid level a
minimum of twice a year.
The master cylinder brake fluid reservoir used on
this vehicle includes a brake fluid level sensor. The
brake fluid level sensor location is in the body of the
brake fluid reservoir (Fig. 26). In the event of low
brake fluid level in the brake fluid reservoir, the
RED brake warning light in the instrument panel
will turn on.
Master cylinder fluid reservoirs on both standard
and antilock brake systems, are marked with a
FULL fill line indicating the fluid reservoirs proper
fluid level (Fig. 26).
NOTE: When filling brake fluid reservoir, use only
MoparT brake fluid or an equivalent stored in a
tightly sealed container. Brake fluid must conform
to DOT 3, specifications. Do not use brake fluid
with a lower boiling point then DOT 3, as brake fail-
ure could result during prolonged hard braking. Do
not use petroleum-based fluid because seal damage
in the brake system will result.
If necessary, add brake fluid to reservoir, bringing
brake fluid level to the FULL fill line shown on fluid
reservoir (Fig. 26).
