Dash illumination and rear lights went out at the same time.

Hi. Thanks for your question. For issues related to brake warning lights on dash illuminated for Mercedes C180, 1996 saloon. You can visit https://www.reliable-store.com and download the entire workshop manual which includes all the information along with the diagrams for better understanding. Good day!

i had the same problem with a 99 acura cl turns out the rear drivers side tail light was removed and there was a plug on the housing that didnt get plugged in prior

Yes. The reason it looks like the lights on the rear of the car and the reason it comes on every time you are hitting your brakes, is because your lamp-out module is trying to tell you that you have a brake lamp that is not working. This is normal function if you ave a burned out bulb or a broken wire in your brake lamps. It does not set any codes, so there is nothing to "reset". Just fix the brake lamp and the warning lamp will go away.

you should have one fuse int the fuse box under the dash on it that controls the gauge illumination panel aka the dash lights and some dummy lights along with it sounds to be blown

Study light? Do you mean warning light?
There are sensors clipped into the brake pads on the front left and rear right wheels. When the brake pads get very thin, those sensors rub on the brake rotors, and the light illuminates in the dash indicating that it is time to replace the brake pads.
The light can also illuminate if something damages the wire to the sensor. I usually replace my pads before they get down to the sensors, so I re-use my old sensors. Although the wires are fairly well secured to the suspension, after a few years, the wires can get chaffed from the wind blowing them around, and the damaged wire can turn on the warning light.

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

The brake fluid level sensor in the master cylinder is stuck in the lower position which completes the circuit to illuminate the light.. Try tapping lightly on the side of the reservoir to loosen it. If that does not help, you will need to replace the level sensor.
Thanks for choosing FixYa for assistance.

check brakes fluid level and also check to see if the sensor was connect back after the pads was change. If all is ok then take it to Auto Zone and they will scan it and clear the code for free also you can clear the code by disconnecting the negative battery lead for 10 seconds but this might make your radio ask for a code in order to play it. good luck

If someone took the time to look at the electrical schematic you will see several grounds in the circuit My first place I would go would be to check all the Grounds and Connections for the Brake Fluid level control, Brake Warning Indicator
The Instrument Panel Cluster (IPC) illuminates the brake warning indicator when one or more of the following occurs:

• The body control module (BCM) detects that the park brake is engaged. The IPC receives a class 2 message from the BCM requesting illumination.
• The electronic brake control module (EBCM) detects a low brake fluid condition. The IPC receives a class 2 message from the EBCM requesting illumination.
• The electronic brake control module (EBCM) detects a closed brake pressure differential switch. The IPC receives a class 2 message from the EBCM requesting illumination.
• The EBCM detects an ABS malfunction which disables dynamic rear proportioning (DRP) . The IPC receives a class 2 message from the EBCM requesting illumination.
• The IPC detects a closed power brake booster alarm switch and closed power brake booster fluid flow alarm switch. The IPC illuminates the brake warning indicator and sends a class 2 message to the radio requesting the brake warning alarm.
• The IPC performs the bulb check at the start of each ignition cycle. The brake warning indicator illuminates for approximately 3 seconds before turning OFF.
• The IPC detects a loss of class 2 communications with the BCM or with the EBCM.

Driver Information Indicators and Messages
The following indicators are used to inform the driver of several different factors.

Brake Warning Indicator
The Instrument Panel Cluster (IPC) illuminates the brake warning indicator when the following occurs.

• The Body Control Module (BCM) detects that the park brake is engaged. The IPC receives a serial data message from the BCM requesting illumination. The brake warning indicator flashes at a rate of approximately twice per second when the park brake is engaged.
• The EBCM detects a low brake fluid condition or base brake pressure differential and sends a serial data message to the IPC requesting illumination.
• The IPC performs the bulb check.
• The EBCM detects an ABS-disabling malfunction which also disables Dynamic Rear Proportioning (DRP) and sends a serial data message to the IPC requesting illumination.

Here is a description of how the system works But i would check my Grounds and connections

Contact me if you need any more information Ill be glad to help

depending on the system if it is 2 channel or 4 channel one of the sensors that are located on the backing plate located behind calipers is eithier faulty or dirty you can try brake cleaner these sensors use a small magnet pickup device to sense when the wheel "locks up"
