SOURCE: Non working brake lights in Nissan Altima

make sure the button is working, it may need to be replaced. with your foot off the brake peddle, it is on upper part of brake peddle arm. when you let off brake peddle it pushes button in to shut lights off. it may just be stuck in, spray a little lubracant on it if it's stuck and push in manually several times to loosen.

SOURCE: how to reset the brake lamp warning indicator and chime

The light will go off as soon as the light or the circuit to the light is repaired, if it is still on and the brake lights work correctly, meaning bright normal not dim looking then the monitor for the lamp out warning is defective, they are very pricey would take the bulbs out if i where you.

Check for bad wiring at the 3rd brake light. You may find frayed or broken wiring there.

SOURCE: Lamp resistance and voltage

1. Projector lamps use customized ballasts that ignite the lamp by charging it with a higher voltage in the ignition phase and then dropping down to a lower running voltage once the circuit is created.

2. Projector lamps CANNOT be tested with an AMP or OHM meter. Projector lamps function by igniting ultra-high pressurized mercury vapor across an ARC tube. At the point where the mercury vapor resides there is no conductive electrical material and therefore testing a projector lamp with an AMP or OHM will not work.

1999 ford escort, parking lights don't go to off, brake lights stopped operating


Could be caused by stuck contacts inside the park lamp relay . The brake light problem could be caused by a faulty brake light switch . This switch is on top of the brake pedal . Check for B+ voltage with a voltmeter before replacing the switch .
The park lamp relay is in the relay box Relay Box

07 cadillac cts has no brake light all fuses are good and replace the brake switch.still not working any advice


Stop Lamps
The brake pedal position sensor is a resistive device used to sense the action of the driver's application of the brake pedal. The brake pedal position sensor provides an analog signal that will increase as the brake pedal is pressed.
The brake pedal position sensor receives both a 5-volt reference voltage and a low reference signal from the electronic brake control module (EBCM). When the brake pedal is pressed, a variable signal is applied from the brake pedal position sensor to the EBCM through the brake sensor signal circuit. The fuse block left rear supplies battery positive voltage to the bass relay switch through the BASS fuse. One side of the bass relay coil is permanently grounded at G402. The EBCM supplies voltage to the bass relay coil upon receiving the signal from the brake pedal position sensor. The switch contacts of the bass relay close and battery positive voltage is applied through the bass relay switch to the center high mounted stop lamp (CHMSL), and to the turn signal/hazard flasher module through the stop lamp switch signal circuit. The ground for the CHMSL is applied from G402. The turn signal/hazard flasher module then supplies voltage to the left and right stop lamps in the tail lamp assemblies that have ground at G401 and G402. For export vehicles the stop lamps receive battery positive voltage directly from the bass relay.

Do you know where the rear fuse box is ? Check BAS fuse 15amp. and the bas relay , should be marked on the inside of the fuse box lid . The rear fuse box is located

Fuse Block - Left Rear
In the passenger compartment, under the left side of the rear seat at carpet
Power and Grounding Component Views
Electrical Center Identification Views
Fuse Block - Right Rear
In the passenger compartment, under the right side of the rear seat at carpet.

If fuse and relay are ok your best would be to take to a cadillac dealer .

I have a 2007 yukon denali xl, I got my front brakes and right wheel hub changed. When he got doney brake lights in the back of the truck wI'll not shut off. Brake light switch did nothing to help..


Who put the front brakes an wheel hub bearing on the vehicle ? A qualified repair shop ? A friend ? The front brakes an wheel hub would have nothing to do with the brake lights . An the brake light switch is an input to the BCM - body control module .
Stop Lamps
When the driver presses the brake pedal, the switch contacts open and battery positive voltage is interrupted to the BCM. The BCM then supplies voltage to both the turn/stop lamp supply voltage circuit and trailer rear turn/stop lamp supply voltage circuits. The BCM also supplies voltage to the CHMSL though a dedicated circuit.
I suggest you take it back to who did the front brakes , or a quailfied repair shop .

My brake lights are staying on even when I unplug the brake light switch


The brake light switch is an input to the BCM - body control module , do you know about BCM'S - electronic module ?
Stop Lamps
When the driver presses the brake pedal, the switch contacts open and battery positive voltage is interrupted to the BCM. The BCM then supplies voltage to both the turn/stop lamp supply voltage circuit and trailer rear turn/stop lamp supply voltage circuits. The BCM also supplies voltage to the CHMSL though a dedicated circuit.

could have DTC'S stored in the BCM
DTC B3445 00: Stop Lamp Circuit
Circuit/System Description
The stop lamp switch is used to sense the action of the driver application of the brake pedal. The body control module (BCM) provides a low reference signal and a B+ reference voltage to the stop lamp switch. When the stop lamp switch contacts close indicating the brakes have been applied, the BCM will apply battery voltage to stop lamp relay control circuit and the center high mounted stop lamp (CHMSL). When the stop lamp relay receives battery voltage from the BCM, the relay coil is energized and the stop lamp relay switch contacts close applying battery voltage to the STOP LAMPS fuse to illuminate the left and right stop lamps.

DTC C0277 00: Brake Pedal Position Sensor Calibration Not Learned
DTC C0297 00: Brake Applied Output Circuit
DTC C0890 00: Device Voltage Reference Output 3 Circuit Voltage Out of Range

In the event that DTC C0277, C0297, or C0890 sets as current in the body control module (BCM) is an indication of a possible internal BCM malfunction or programming error. There are no external circuits available to diagnose on this vehicle with respect to these DTCs.
Your best bet would be to take your vehicle to a qualified repair shop or the Cadillac dealer.

I have saturn ion3 sedan 2005 . My stop light not working. I checked the switch and fuse. They are OK. But didn't find relay. Where I can find it? Thank you.


The 15-amp STOP fuse located in the body control module (BCM) supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to both left and right stop lamp assemblies and the center high mounted stop lamp (CHMSL), through the BCM. The stop lamps are grounded at G401 and G403.
Do you know where the BCM is located ? If it should come down to it that the BCM needs to be replaced , It has to be programmed an the dealer is your best bet !
Replace the BCM. Refer to Control Module References for replacement, setup, and programming.
There is no relay ! !
Do you know where the BCM is located

Where is the stop lamp or brake lamp fuse and panel for a 2007 cadillac cts?


Kevin , this is a very complex way of stoplamp control , I will post GM service Description and Operation of how they work an let you deside if you want to tackle this ! Do the center high mount brake lights work ?
The brake pedal position sensor is a resistive device used to sense the action of the driver's application of the brake pedal. The brake pedal position sensor provides an analog signal that will increase as the brake pedal is pressed.
The brake pedal position sensor receives both a 5-volt reference voltage and a low reference signal from the electronic brake control module (EBCM).

There could be a code stored in the EBCM - electronic brake control module - DTC B3903 Stop Lamp Relay Circuit
DTC C0278 Brake Pedal Position Sensor Not Calibrated
there are several other codes that pertane to the brake lights . you could try Replaceing the bas relay !

Is there a fuse or relay or micro relay for the CHMSL on 98 sts


check the lt blue wire at upper lamp,(under trunk lid trim panel) for 12 volts when brake is applied. if no voltage,check same color wire at brake lamp switch for voltage.(by brake pedal).if no voltage replace stop lamp switch asm. if voltage is detected at rear by lamp then replace CHMSL asm.(center high mount stop lamp). this lamp is made of many LED's,if some work and some don't you will need to replace lamp asm. can be repaired by a trained GM tech, possibly. there is no seperate fuse or relay for this lamp,only a stop lamp fuse.

Where is the 97 tiburons (light blue) brake relay located?


there is no stop lamp relay on this model. See diagram below. If your stop lamps aren't working, check the fuse (#3, 15 amps) and the brake light switch above the pedal. Please let me know if you have any questions.

Click on the link.
Did you check fuse circuit for voltage? Use a test light with headlamp switch on to check for voltage. See the park lamp relay, I'm not saying the relay is faulty, but, you might be able to use jumper wire on load side of relay, if lamps work, the problem is on control side of relay, for some reason.
The load side of relay is that line with arrowhead. There could be other issues.
