I need to replace the abs module. How does the wiring harness disengage from the module?
My car has 157000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
First, replacement of the ABS control module is a big job that requires opening up the hydraulic system and bleeding the brakes afterwards. I recommend having this task performed by a professional, such as one from YourMechanic. If you’re sure this is something you want to do yourself, you can remove the electrical connector by doing the following: push in the locking tab and pull up on the lock of the ABS control unit and the connector disconnects itself.

Yes, you can `bypass` the ABS system altogether just by doing nothing. Eventually the pump will run dry and the dash light will light up indicating you do not have a working ABS system. This is not really a problem. You still have full braking power, just not the ABS assist, which has always been of questionable value.
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car`s braking performance.
The ABS module will need to be programmed once everything is installed. This procedure also will vary quite a bit depending on the manufacturer. Tip: For this step in the ABS module replacement procedure, refer to the manufacturer`s instructions to find the specific programming procedure.
2. ABS Module. The ABS control module is a microprocessor that runs diagnostic checks on a vehicle`s anti-lock braking system and controls the ABS modulator. It uses data from the speed sensor to manage the valve system in the ABS modulator to restore hydraulic pressure.
The anti-lock function will stop working properly, which may increase the distance it takes to safely stop your vehicle. The rear tires will lock, which will increase vehicle swing on turns and may make your vehicle more difficult to control.
During an emergency brake (possibility of wheel “block”) the ECU controls the electromagnets of two valves simultaneously causing them to operate. The input valve releases the brake chamber from the master cylinder and the output valve connects it with the hydraulic accumulator, thus reducing the pressure.
In order to operate, your ABS system needs electricity. This is controlled by the anti-lock fuses and relay. The first fuse (a 10 amp fuse) must be good in order for electricity to flow to the relay, and the relay must function to provide power to the second fuse (a 30 amp fuse).
As one of the most important parts of a working car, your vehicle`s brakes are designed to work no matter what happens to the ABS system. So, yes, your car will still be able to stop without ABS. However, it`s not recommended to drive without ABS if your car is equipped with it.
You can`t “bypass” an ABS sensor. You need to get the problem repaired. Then the light will go off ( usually by itself). If you want to disable the ABS system ,remove the fuse.
The most convenient means of reprogramming is the use of the DLC interface. This can be accomplished with a scan tool or an SAE J2534 pass-through interface.

In fact it can only be programmed once, so it will stay programmed to it`s original car. That won`t matter, though since they are similar cars.

What should i check before replacing the ABS module
ANSWER : Hello There,
It sounds like you may have some faulty wheel speed sensors that may be causing the ABS light to come on. Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS and traction control system which are controlled by the car’s ECU. When the ECU senses an abnormal speed given specific conditions, it engages the ABS or traction control as needed to control the vehicle properly and safely. Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. The ABS or traction control system may be inadvertently activated by these false or inaccurate signals. I would suggest having a professional from Your Mechanic come to your home to diagnose your ABS and traction control system.

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.
I have a 2016 kia forte. A rodent ruined my wiring harnesses causing safety and operational issues. Kia says the harnesses have to
ANSWER : Hi there. The automotive manufacturer is 100% correct in their estimation about splicing a wiring harness. Today’s vehicles are 100% controlled and monitored by electrical and computer operated systems. These systems require a clear and unaltered wiring system that sends electrical signals from sensors and components to the ECU and back. Splicing or altering the wiring in any way is very unsafe and can disable several safety systems including air bags, anti-lock brakes and other systems.
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).

I need to know which body wiring harness goes to my truck- VIN lookup
ANSWER : My best recommendation would be to contact your local dealership. If you give them your year, make, model, vin, and a description of the wiring harness that you need, they should be able to give you some information in regards to the part number. Unfortunately, the dealership is about the only possible chance of tracking down this harness other than getting one from a junk yard.
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.
My ambient air sensor needs replacing. A rat got in the engine compartment and chewed away the wire. So probably need to splice a
ANSWER : Such a repair can be performed by a certified Mechanic, dispatched by YourMechanic right to your location if you request an electrical circuit/component diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
