Question about 1991 Buick Park Avenue

1 Answer

The brake light came on and brake pressure went to zero

Driving at low speed <20 mph, the brake light came on and brake pressure went to almost zero. Is there a fuse that controls power to the brake pressure on a 1991 Buick Park Ave., or is this most likely a master cylinder problem?

ABS CHECK LIGHT DOESNT COME ON WHEN YOU TURN KEY ON


1. I would not be concerned because if there was a failure in the ABS you would definitely get an ABS warning light and the ABS and most likely the stability control/traction control systems (with added warning lights) will all switch off .

2. You can test if the ABS is operational. On a very quiet damp surface, straight, wide road( with NO other cars around), apply your brakes hard from a very low speed - up to 20 mph ONLY driving in a straight line - until the car stops. The front brakes should attempt to lock up under hard braking and if the ABS is operational you will feel it kick in and the brake pedal will pulsate as the ABS constantly allows brake pressure and then releases it to prevent the wheels from locking up on the damp road. If the ABS does not kick in be ready to release the brake pedal quickly to allow the wheels to rotate so you can steer the car safely. Without the ABS the front wheels should begin to lock up on the damp road surface due to the low level of tire grip. ONLY test this at very low speed and ONLY when driving in a straight line on a straight section of wide road with no other vehicles around.

How do you reset the low tire pressure light?


To reset the tire pressure system, do the following:

(NOTE!....Do not reset the check tire pressure system without first
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.)

1. With the engine off, turn the ignition to ON.
2. Press the MODE button until the DIC reads LOW
TIRE PRESSURE HOLD SET TO RESET.
3. Press and hold the SET button until you hear a
chime, and TIRE PRESSURE RESET is displayed.

You will hear three chimes, then the LOW TIRE
PRESSURE message will go off and the DIC will return
to TIRE PRESSURE NORMAL. If the LOW TIRE
PRESSURE message comes back on, the check tire
pressure system has not reset. Repeat the procedure.
The system completes the calibration process during
driving. The system learns the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 30 and 60 minutes of
driving to learn the tire pressures. The system normally
takes 10 to 20 minutes of driving in each speed range to
learn tire pressures. The speed ranges are 20 to 40 mph
(32 to 64 km/h), 40 to 60 mph (64 to 96 km/h), and above
60 mph (96 km/h). This time may be longer depending on
your individual driving habits. The learning process does
not need to be completed during a single trip. Once
learned, the system will remember the tire pressure until
the system is reset.

My low tire light came on so I went and had air and all the tires checked but now I don't know how to turn the light off. I have had the car since 2000 and it has 50,000 miles on it but could never figure...


Hello Mattingly.

Here is some information for you regarding your problem.

The Tire Inflation Monitor (TIM) system alerts the driver when the pressure changes in one of the tires. The system only detects a low pressure condition while the vehicle is being driven. Once a low tire pressure condition is detected, the system informs the driver that a low tire pressure condition exist's, whenever the ignition is ON.
The LOW TIRE message appears on the Instrument panel if the tire pressure in one tire becomes at least 82 kPa (12 psi) lower or higher than the other three tires. The message does not appear if more than one tire is low or high, or if the system is not calibrated properly. The system does not inform the driver which tire is low. To clear this message, set the tire pressures in all four tires to the proper pressures and perform the system reset procedure. Refer to Tire Inflation Monitor Reset Procedure for service procedure.
The Tire Inflation Monitor software requires approximately one half hour of straight line driving to complete the TIM autolearn. There are several speed ranges that the EBCM needs to learn the tire inflation configuration in order to have the full capability of detecting a low tire condition. The speed detection ranges are the following:

  • 24-64 km/h (15-40 mph)
  • 64-113 km/h (40-70 mph)
  • 113-145 km/h (70-90 mph)
Each speed range has 2 modes of low tire detection.

  • Monitor Mode 1
  • Monitor Mode 2 The EBCM learns the tire inflation configuration for each speed range independently. In Monitor Mode 1, the EBCM has only partially learned the tire inflation configuration for the speed range and has limited detection capability for a low tire condition. In Monitor Mode 2, the EBCM has fully learned the tire inflation configuration for the speed range and has full detection capability for a low tire condition. If the EBCM is not in Monitor Mode 1 or Monitor Mode 2, a low tire condition cannot be detected because the EBCM has not learned the tire inflation configuration of the vehicle.

To reset (calibrate) the system:
Turn the ignition switch to RUN. Then press and hold the RESET button for about five seconds. The red RESET button is located inside the instrument panel fuse block on the right side of the dash.. The LOW TIRE light will come on and flash three times and then it will turn off.
The system completes the calibration process during driving.
The system normally takes 15 to 20 minutes of driving in each of three speed ranges to "learn" tire pressures. The speed rages are 15 to 40 mph (25 to 65 km/h), 40 to 65 mph (65 to 105 km/h) and above 65 mph (105 km/h).

There you are, this should fix you up.
Keep in mind this system uses wheel speed sensors to calculate. If one of your sensors isn't working your low tire light will remain on.

Thank you for using FixYa.

Unless you really know what you are doing it is best to get a mechanic to repair this. People's lives and safety are at risk and you could be held legally if something went wrong with your repair job. I would not touch it.

Changed right front tire now reads zero on dash light is on


Your tire pressure monitor needs to be reset whenever you change or rotate your tires...

1. check and make sure that your tires are inflated to the correct pressure

2. turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns off and then release the switch.

3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.

4. initialization is *not* completed until driving at the vehicle speed of 19 mph or over for more than one hour. the tire pressure monitoring starts when initialization is completed.
