Door Control Modules are placed inside both doors. They manage all actuators in the driver- or passenger door and are directly connected to a separate switch panel. Central Locking, Window Winders as well as Mirror Adjustment are controlled by this ECU.
What is the Smart Entry System? The Smart Entry System is a newer technology feature that makes it possible to lock and unlock your vehicle without using a key or a key fob.
Unfortunately, any control module needs to be flashed or reprogrammed to link to the sensors and monitors of an individual vehicle in order for them to work correctly. This needs to be completed by a dealer or some automotive specialists, as they control security codes to reprogram these systems.
The main components of the smart lock include the physical lock, the key (which can be electronic, digitally encrypted, or a virtual key to provide keyless entry), a secure Bluetooth or Wi-Fi connection, and a management mobile app.
The BCM communicates with other on-board computers via the car`s vehicle bus, and its main application is controlling load drivers – actuating relays that in turn perform actions in the vehicle such as locking the doors, flashing the turn signals (in older cars), or dimming the interior lighting.

Smart Entrance Control Module needs replacing
ANSWER : The SECM may be ok. It may have a power issue due to a blown fuse or relay. The SECM is an expensive part and may require factory level programming. I suggest having a qualified technician fully inspect your vehicle’s electrical system before condemning the SECM.

transmission control module failing. We just replaced the computer module (pcm) 4 days ago?
ANSWER : The P0700 trouble code is a code for transmission control module (TCM) failure. Without knowing the other codes, it will not be possible to give you an accurate answer; it all depends on the other codes:

If you get a P0755 code, you may have a transmission solenoid pack issue.
P0725 indicates a likely crank position sensor issue.

I would suggest having your Check Engine Light diagnosed by a qualified mechanic.

Does the whole steering column need to be replaced in order to replace a fried steering column module?
ANSWER : I would ask the mechanic for the exact part number of the electronic component that he believes has failed. Or, at least have him "name" the part and indicate where in the column assembly the part resides. The steering column is made up of many parts, most of which are separately serviceable. As discussed below, limp mode (reduced power) has many, many causes. Consequently I would also ask the mechanic to explain to you EXACTLY how he arrived at his diagnosis and ALSO have him show you the exact test results, on a diagnostic tool, multi-meter, or scope, that has led him to conclude that the particular "module" has to be replaced. With no evidence and no intelligible confirmation you would be taking a risk.

YourMechanic does offer a reduced power (limp mode) diagnostic. If you request a reduced engine power diagnostic the responding certified mechanic will give you confirmation of the cause of the issue in your case. Typically, a vehicle’s powertrain control module (PCM) will have stored one or more diagnostic trouble codes that will identify the "general area" in which the fault lies in the engine management controls. Although the throttle control system is a common trouble area with reduced power, there are quite a few other components and systems that could come into play and, of course, there is always the possibility of multiple, or "coincident", faults. Here are some of the possibilities that YourMechanic dispatched technicians would consider:

Defective throttle position (TP) sensor
Defective oxygen sensor
Defective accelerator pedal position (APP) sensor
Loose or damaged wiring
Defective throttle body
Defective powertrain control module (PCM) (not typical; ONLY if a long, long list of other possibilities is ruled out)
Any fault/error that will affect drivability function
Any fault/error that will affect vehicle performance
A fault/error in the emissions system
A fault/error in the throttle control system
A fault/error in the transmission control system

If you request the recommended diagnostic the mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ABS, ESP, EBR malfunction
ANSWER : You’re getting into an area that is kind of a dark art when you’re getting these kinds of codes. While I don’t know any of the symptoms that the car is exhibiting, I can tell you that failure in one of the control units can lead to codes showing up in the others and the ABS, ESP is a likely culprit since it interprets the wheel speed signals and sends the information to the other modules. You’re right that the module has to be coded, and I don’t think that Snap On has the software for that so the only place to go is the Star Diagnostic. (The consumer version of the Mercedes SDS ) You can Contact YourMechanic and see if anyone in your area has the appropriate equipment for this. Otherwise, this may be a case that would best be consigned to the Mercedes Dealer.

Do i need to replace the receiver drier and/or the expansion valve when replacing the condenser assembly?
ANSWER : Replacing the system drier is absolutely essential. If the system has been open to the atmosphere (due to the leak in the condenser), the desiccant in the drier has been fully saturated with moisture. As far as the expansion valve, replacement is not normally implicated in a leak repair, in your case a leak in the condenser. To justify replacing the expansion valve, there would have to have been a diagnostic performed which proved a fault. If no diagnostic was performed, and there is no evidence of a fault, then it is pointless to replace the valve. But, again, drier replacement is absolutely essential. To add the drier to your order, you can simply add a note to the mechanic in your order and/or add it as a service (you will see a link that you can click on to "add services" or write in specific services). If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

When replacing ball joints can you just replace the ball joints or do you need to just replace the control arm?
ANSWER : Suspension components on modern vehicles are not as heavy as they used to be. Components like control arms can be lighter and thinner. Ball joints are riveted or pressed into control arms. Sometimes bolted/screwed. Since replacing a ball joint will usually involve removing the control arm from the vehicle to either press or drill rivets out – which is more labor intensive, it can be a time and money saver labor wise to simply replace the entire control arm.

You are removing the old control arm and replacing it with a new one, complete with new ball joint and control arm bushings. Even if the control arm bushings are in good shape at the time the ball joint is replaced, they will eventually require replacement. You then have parts and labor involved again to remove the control arm, replace the bushings, then reinstall it on the vehicle.

Sometimes the ball joint replacement can be more cost effective in the long run, to simply replace the entire control arm. If you’d like to have this done, consider YourMechanic, as one of our mobile technicians can come to your home or office to service your ball joints.

Can I get front upper ball joints for our 2007 Ford Edge? I don’t need the entire control arms, for they don’t need to be replaced
ANSWER : The front suspension system on the Edge incorporates a strut assembly that takes the place of the upper arm and ball joint. There is a lower arm assembly though on your vehicle. If you desire to replace just the ball joints in the lower arms, Moog, AC-Delco and Mevotech all vend these lower arm ball joints separately. You’ll want to very carefully evaluate the rubber bushings in the existing arm though though. Generally, rubber based products (control arm bushings) are at the end of their service life once you get to 6-8 years or so. If wear in the rubber allows the control arm to move even .020 inches, it can make it technically impossible to align the vehicle. The tolerances are very small in front end alignment. If you desire that this issue be inspected and resolved by a certified mechanic, please request ball joint replacement and the responding certified mechanic will address all of your concerns. If you have further questions, do not hesitate to re-contact YourMechanic as we are always here to help you.

When replacing my ball joints on my 2005 dodge Strauss do I need to replace the control arms as well
ANSWER : Hi there. When changing out the ball joints, you don’t need to change the control arms if you have a replacement ball joint. However, if you are wanting to replace the bushings and the ball joint, then you may get a better deal when buying a control arm with the bushings and ball joint already installed. I suggest checking the bushings on the control arms before making your decision. If you need further assistance with replacing the control arms, then seek out a professional, such as one from Your Mechanic, to help you.
