Why does my check braking system light come on?

Any warning lights lit on the insturment cluster ? ABS
Vehicle Speed Signal
The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-wheel anti-lock brake system (4WABS) module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input.
Speedometer
The electronic speedometer receives a speed signal from the 4WABS module.

Take it to a qualified repair shop .

Brake Hydraulic System Red Warning Light - RepairPal

repairpal.com/brake-hydraulic-system-red-warning-light
If the brake hydraulic system red warning light comes on and stays on, this indicates... and seems to come on and off depending on whether the vehicle is turning, ... if it is discovered that the light was illuminating due to a low brake fluid level.

Check cable which plugs into back of instrument cluster. Also fusible links.

Have a shop check for codes & check their
data base, to learn how to diagnose the issue

Same procedure as any vehicle problem

Stop using it & get to work looking for any problem
& resolve them, as you find them

The light may go away,but not the problem,get it fixed

Hi Douglas, The ABS warning light is indicating a fault with the system. The vehicle can be driven, but the Anti Lock System is not working. The best course of action is to take the vehicle for a diagnostic scan and find out where the problem is. It is most likely to be with one of the wheel speed sensors, which may need cleaning or replacing. That is not to say that is the problem, only the most likely. Regards John

check your brake fluid levels, if low there may be a leak in the system. If ok, check the ABS system for malf.

Could be a fan clutch. It allows the fan to "slip" up to speed and can make a wind noise untill it gets up to speed.

I had a Mazda 626 with a similar problem, the car seemed to 'shut down' with no warning, even at highway speeds, as if I just turned the ignition key to 'Off'; After trying to fix it unsuccessfully by replacing several electrical parts, the problem was found to be a defective ignition switch, it was replaced and the problem went away.

Anti-Lock Control —Vehicles Built After 03/2002 The 3-channel anti-lock brake system consists of the following components:

• front wheel speed sensors
• front wheel speed sensor rings
• hydraulic control unit (HCU)
• Anti-lock brake control module (ECU)
• rear wheel speed sensor
• rear wheel speed sensor rings
• yellow anti-lock brake warning indicator

The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components:

• active brake booster with integral solenoid
• brake booster release switch
• front wheel speed sensors
• front wheel speed sensor rings
• hydraulic control unit (HCU)
• stability assist module (ECU)
• stability assist event indicator
• lateral accelerometer
• longitudinal accelerometer (4x4)
• rear wheel speed sensors
• rear wheel speed sensor rings
• steering wheel position sensor
• yaw rate sensor
• yellow anti-lock brake warning indicator
• brake pressure transducer
• traction control switch

---------------------------------------------------------------------
I suspect the abs issue is causing the speed control not to work if it happened at the same time the cruise control stopped working. When the yellow ABS light comes on, it means the ABS is dactivated. You may have a faulty accelerometer which senses acceleration and yaw (side to side lean). I have not seen a bad one but you said it is sensitive to acceleration.
I would unplug it and see what happens. The connector should have a small tab to depress so you can pull the connector out.
Here is where it is:

Accelerometer Removal and Installation

1. NOTE: The accelerometer is located under the center, rear passenger seat carpet. (I think you have to remove seat for access).
   Cut the carpeting along the perforations.

1. Disconnect the electrical connector.

1. Remove the nuts and remove the accelerometer.

Have dealer hook up tester and pull fault codes if you can't find an easy solution.
Some background info

A malfunction in the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.

Malfunctions are indicated by the yellow ABS warning indicator in the instrument cluster.

The anti-lock brake system is self-monitoring. When the ignition switch is turned to the RUN position, the anti-lock brake control module will carry out a preliminary self-check on the anti-lock electrical system indicated by a three-second illumination of the yellow ABS warning indicator in the instrument cluster.

During vehicle operation, including normal and anti-lock braking, the anti-lock brake control module monitors all electrical anti-lock functions and some hydraulic operations.

Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20 km/h (12mph), the anti-lock brake control module turns on the pump motor for approximately one-half second. At this time, a mechanical noise may be heard. This is a normal function of the self-check by the anti-lock brake control module.

Pedal pulsation coupled with noise while braking on loose gravel, bumps, wet or snowy roads is normal and indicates correct functioning of the anti-lock brake system.

Warning Lamp Indicator
The anti-lock brake system (ABS) uses the yellow ABS warning indicator to alert the driver of a malfunctions in the ABS.
The yellow ABS warning indicator will come on to warn the driver that the ABS has been turned off due to a symptom that exists in the ABS. Normal power assist braking remains but wheels can lock during a panic stop while the yellow ABS warning indicator is illuminated.

Please report back, I am curious if that is what it is. Good luck

Most new cars nowadays have Wiring-Check systems, which are themselves a bunch of extra wiring to make sure the wiring to, in this case, your brake lights works. Its somewhat rare, but does happen, the wiring on the Brake Light Function Check system probably has a bad ground, explaining the internittent illumination of the warning light.

Unfortunately repairing it would have to be done by a more than competent and qualified Acura technician, which may be hard to find because a wiring fault of this kind is generally a very hard one to find. Unfortunately some dealerships will probably take the car in, look it over, figure out whats wrong and decide "I'm not doin that" and tell you they can't figure it out.

When this happens, most people just put a piece of electrical tape over the Warning light in the dash so that you can't see it anymore. Because if the Warning Light is on, but the brake lights still work, then there is nothing actually wrong with the brake light system.
