Ninety-Eight V6-3.8L VIN K (1995)
Brake Warning Indicator: Description and Operation
Circuit Operation
The BRAKE indicator receives battery voltage when the ignition switch is in "RUN," "BULB TEST," OR "START." Three switches are connected to
the bulb so that when any one closes, the indicator lights. The ignition switch "BULB TEST" position does not have a detent, but the ignition switch
should close to ground and light the BRAKE indicator before the "START" position is reached.
The master cylinder brake fluid level switch closes to light the BRAKE indicator and briefly sounds a fast chime when there is low brake fluid in the
hydraulic brake systems. This could be caused by a leak in one of the brake lines. The switch opens by refilling the reservoir to its normal level. Make
sure the brake system has been repaired before filling the master cylinder reservoir.
The park brake switch closes when the park brake is applied, lighting the BRAKE indicator. Vehicles equipped with U2E clusters also briefly sound a
fast chime after the vehicle has traveled approximately 50 feet. Vehicles equipped with UH8 or U2A clusters briefly sound a fast chime when the gear
selector lever is moved out of "PARK" or "NEUTRAL." Releasing the park brake opens the switch and turns off the BRAKE indicator.
