Those are two different things, but for the EBCM, there will be a small locking clip that needs to be slid out of the connector. Next the connector has a "arm" that you will lift to disengage it.

SOURCE: Squeak in front end

Okay....I have been working on my boss' car for a week with this SAME issue....first....try to figure out the spot it is coming from. This part is the pain. Second, have a can of WD-40 and spray it into any joint you find. This squeek could be from an upper bushing, a lower bushing, an A arm bushing, or any other bushing on that side....so start out with this method first because it will only cost you a few dollars, or free if you have it already. But do one at a time till you find it. Then, you'll know what item to replace.

Can leaky shocks on a 2006 Cadillac DTS cause the traction control light to come on


If the light is on there are DTC'S - diagnostic trouble code's stored in ABS - anti - lock brakes computer . Have codes checked first , something wrong with electrical part of antilock brakes , I know, what does ABS have to do with traction control ! traction control is a function of the ABS control module . Leaking shocks ? clarify , air shocks etc.... Before you start guessing , have it check for codes .
This vehicle is equipped with the TRW 440 V antilock braking system.
The vehicle is equipped with the following braking systems:
?€¢
Antilock Brake System (ABS)


?€¢
Engine Drag Control (EDC)


?€¢
Dynamic Rear Proportioning (DRP)


?€¢
Traction Control System (TCS)


?€¢
Vehicle Stability Enhancement System (VSES) (w/JL4)

The following components are involved in the operation of the above systems:
?€¢
Electronic brake control module (EBCM)--The EBCM controls the system functions and detects failures.


?€¢
Electronic brake control module (EBCM)--The EBCM controls the system functions and detects failures.


The EBCM contains the following components:


-
System relay--The system relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves and pump motor.


-
Vent tube--The vent tube, located in the EBCM connector, is an opening to the internal cavity of the EBCM. It allows ventilation of the EBCM internals.


?€¢
Brake pressure modulator valve (BPMV)--The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.


Important: There is a rubber isolator located under the BPMV and on the mounting studs. The rubber isolators protect the BPMV and the EBCM from vehicle vibrations.


?€¢
The BPMV contains the following components:


-
Pump motor


-
Inlet valves (one per wheel)


-
Outlet valves (one per wheel)


-
Master cylinder isolation valves (one per drive wheel)


-
Prime valves (one per drive wheel)


?€¢
Wheel speed sensors (WSS)--As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses this AC signal to calculate wheel speed. The wheel speed sensors are replaceable only as part of the wheel hub and bearing assemblies.


?€¢
Traction control switch--The TCS is manually disabled or enabled using the traction control switch.


?€¢
Stoplamp switch--The EBCM uses the stoplamp switch as an indication that the brake pedal is applied.


?€¢
Lateral accelerometer sensor (w/JL4)--The EBCM uses the lateral accelerometer sensor as an indication of the lateral acceleration of the vehicle.


?€¢
Yaw rate sensor (w/JL4)--The EBCM uses the yaw rate sensor as an indication of the yaw rate of the vehicle.


?€¢
Steering wheel position sensor (SWPS) (w/JL4)--The EBCM uses the SWPS as an indication of the position and rotation of the steering wheel.


This systems are very complex , your best bet would be to take it to a qualified repair shop .

How to diagnose an ABS problem


You need to find out what code is stored in the ABS control module, if the light is on there is a DTC an the system is disabled ! Don't know if auto part stores can pull ABS codes or not , You'll have to check it out . Personally I say take it to a ASE certified repair shop if you don't know anything about anti lock brakes !

Co196 yaw rate sensor re accruing problem


Good day and welcome to Fixya!
Yes it's considerable to reprogram the ebcm. But before you do that, try to remove the positive battery connector and leave it for atleast 5mins. then put it back on. Try to scan it again. If same issue occurs then I strongly suggest the reprogram.
Hope this helps and thank you for using FixYa!

Why does the ABS system keep activating in my 2005 tahoe for no reason mostly on take off?


most likely you have a wheel speed sensor problem and one sensor is dropping out causing traction control to kick in. this works off of abs system. if your abs motor is just running all the time the ebcm has internal failure and would need replacing. there is a ground wire on left side of frame would be rt under drivers side body mount behind front tire. try cleaning this area by removing bolt and scuffing frame if it gets corroded abs will do some funny things. worth a shot wont cost you anything.
