2007 Cadillac CTS No Brake Lights In Iluding The Third Brake Light


Is the EBCM energizing the BAS relay to turn on the brake lights ?
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.

Did you have a qualified repair shop check for DTC'S - diagnostic trouble codes ?
DTC B3903 Stop Lamp Relay Circuit
The electronic brake control module (EBCM) supplies voltage to the BASS relay coil side voltage supply circuit when the stop lamps are active. The coil side control circuit of the BASS relay is permanently grounded at G402.

DTC C0278 Brake Pedal Position Sensor Not Calibrated
The brake pedal position sensor (BPP) is a potentiometer. The electronic brake control module (EBCM) supplies a 5-volt reference circuit and low reference circuit to the BPP sensor. The BPP sensor signal circuit is a direct input to the EBCM. The EBCM determines the BPP based on the voltage from the BPP sensor. The EBCM converts the BPP sensor feed back voltage to a digital signal and puts it on the class 2 communication bus.

DTC C0282 Brake Pedal Position Sensor Circuit Range/Performance
DTC C0283 Brake Pedal Position Sensor Circuit Low
DTC C0284 Brake Pedal Position Sensor Circuit High
DTC C0880 Device Voltage Reference Output 2 Circuit

Without knowing if any of these DTC'S are stored do not know what diagnostic direction to point you in .

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.

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 .

Back lights won't come on changed bulbs can't find 5he fuse


we need :
mfg name of monitor (vast)
model name (vaster)
product p/n , like viewsonic, VA22xxxxxx ?
there are no 2 monitors alike, and never will be..
be specific.
my guess you are working an old cold cathode florescent tube LCD monitor. (yes, ive mixed many)
it has 3 parts. (a/c power, fuse, power pack, and the tubes)
check for power to the power pack (highvoltage it is)
120vac in (usa) and hv out for the tubes.
if the power to it is good and the tubes are dead, the pack is Dead.
this is the #1 failure mode for all old LCD.
the pack dies. and costs more than a new or used monitor.
but it is true fleabay sellers do rip them out and sell them used.
but usually dont last long. due to Age.
btw too, a full manual (with schematcs) can had, but usually costs $$$

Ford f-250 taillights wont work bulbs new everything else works??? 1999 model checked fuses


check the rear whip,usually right under the bumper where the left side and right side come together,un-tape everything and check the brown wire and connection,if looks green with corrosion then cut it and re-solder it and seal with insulating wire wrap or shrink wrap tube---its for the tail lights or parking lights

Disconnect all speaker wires from the amp and disconnect the RCA cables from the amp. If it still goes into protect mode, use a multimeter to confirm that you have 12v on the B+ and remote terminals. Place the black meter probe on the ground terminal of the amp when measuring the voltage. If the voltage is sufficient and the amp goes into protect, it will have to be repaired. JL only accepts repairs from authorized dealers. You'll have to find one in your area or you'll have to find a repair shop willing to work on JL amps.

Let me know if you have any other questions.
