What caused the brake sound from fusing unit?

If your 2007 Impala is stuck in park and the gear override silver button doesn't work, there may be a few potential problems that are causing the problem. Here are some common causes and troubleshooting solutions you can try: Brake light switch: The most common cause of this problem is a faulty brake light switch. The brake light switch is responsible for sending a signal to the shift interlock solenoid to release the shifter when the brake pedal is depressed and can prevent the shifter from releasing if the switch does not operate properly. Make sure your brake lights work by pressing on the brake pedal. If they don't work, it's probably a brake light switch issue that needs to be replaced. Shift Interlock Solenoid: The shift interlock solenoid is a mechanism that prevents the shifter from moving without pressing the brake pedal If the solenoid is faulty or a blown fuse can cause the shifter to go into park. Check the fuse connected to the shift interlock system and replace if necessary. If the fuse is good, the solenoid may need to be replaced. Shift Cable: The shift cable connects the shifter to the transmission and allows you to change gears. Damaged, loose, or misaligned cables can prevent the shifter from leaving the parking space. Inspect the shift cable for any obvious issues and make sure it is securely attached to the shifter and transmission. Shift lock control module: Some vehicles have a shift lock control module that ensures proper operation of the shift interlock system. Malfunction of this module can cause the problem. It may be necessary to use a diagnostic scan tool to check for any error codes associated with the module. Ignition switch: Faulty ignition under certain conditions

The flasher unit is located under the dash, near the steering column. This could also be caused by a faulty ground wire. Check the wiring for broken, bare, or loose wires or connections.

Possibilities are brake switch, fuse, or grounds. Since all three are out. Grounds are usually on the drivers side attached to the frame by the left tail light assembly. I would recheck the fuse if you didn't pull it out and look at it. Corrosion can cause the lights not to work, but the fuse is good.

Many of these require that you apply brake n order to put it into gear. Fuse probably is in circuit for brake pedal to let control unit know you have foot on brake. It is likely that the in-line fuse holder has broken (quite common) and thus the fuse fell out. Remove any under dash panels as needed to be able to see into this area, and you should find a wire with a part of broken fuse holder attached. Find the two ends and splice in a new fuse holder and fuse=fixed!

hi. does this sound familiar.

Anti Lock Brake System (ABS) problem. Has trouble code C1243.

1. Pin test power and ground to the Electronic Brake Traction Control Module (EBTCM).

2. Stress test the power and ground by using a high beam headlight or blower motor to put a load on the system.

3. If power and ground are OK, remove the EBTCM and hot wire the pump motor. If it runs OK and is quite, replace the EBTCM. If the motor is noisy replace both the Motor and the EBTCM.

Brake Pressure Modulator Valve (BPMV) - BRAKE PRESSURE MODULATOR VALVE WAS NEEDED

Precor Error 54, Target Pulses Lost During Operation Probable Cause 1. Blown F2 fuse.
2. Gear motor wiring is damaged or has intermittent connection.
3. Gear motor is bad.
4. Gear motor target is damaged.
5. Lower PCA is bad.
Corrective Action

1. Disconnect power from the unit. Remove the F2 fuse from the lower PCA. Using an ohm meter, measure the fuse for 1 ohm or less. If the reading is considerably high, replace the fuse. If the fuse is blown, inspect further for the cause to avoid the fuse blowing again. Inspect for damaged gear motor wiring or a bad gear motor. Replace if necessary.
2. Thoroughly inspect the gear motor wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
3. With unit disconnected from power, disconnect both wires from the gear motor. Using an ohm meter, check for approximately 9 ohms through the gear motor wiring. If the reading is considerably high or low, replace the gear motor.
4. Inspect the gear motor target for rips, tears, or bad scratches. If any of these are found, replace the target.
5. During the start up sequence, check the voltage at the gear motor. Voltage should be approximately 12VDC. The voltage should only be present between the time the sequence was started and the error 53 occurred. If the voltage is considerably low or absent and the F2 fuse proved good, replace the lower PCA.

Sounds like a short in the brake light switch or at the bulb sockets themselves.

I think your brake shift interlock solenoid is not releasing the Park position when you apply the brake.

Check for a blown fuse first. see owner manual for location of fuse.

Also, check owner manual for how to manually bypass the interlock.

When you step on the brake pedal, it activates a solenoid that unlocks the shift linkage cable so it will move. It is a safety feature to ensure you have you foot on the brake and not the gas, as you shift out of park.

please rate highly if this helps.

Sounds like a fuse, in the underhood fuse box, the brake lights & cruise are on the same 20 amp fuse. After replacing the fuse, check the brake lights first. Then see if the horn works, horns usually are the cause for a blown fuse, they short out.

This problem sounds like and ABS module that has gone bad, the ABS module has toothed gears inside that actuate the ABS motor, if one of these gears slips a tooth or "unwinds" itself if will not circulate brake fluid to where it needs to go (ex: the rear brakes) alot of times the brake and ABS light will come on, but will not set any trouble codes. My recommendation is to take this to a repair shop and have them verify the problem and replace the ABS module, the motor gears have to be properly aligned when replacing or the lights will stay on and you will still have the same problem. Hope this helps.
