How do i service traction system


You will need to diagnose the code first. The traction control and abs systems are tied together, usually there is a bad wire on the front end. The way the wires are routed for the abs system makes for cut or pinched wires to one of the front hubs causing an open circuit to one of the sensors for the abs system. This causes the traction control system to quit working. Diagnosing the trouble code should tell you where to look

Anti lock break is on. Break pads still at 50 + % What could be the problem?


If you don't own an OBD II scanner go to your nearest Autozone and have them try to lift the ABS code from your vehicle using one of their scan tools. If they can't find it then go to a a repair shop that has a better scan tool, such as GM's Tech 2 or equivalent, and have them lift the codes. The Tech 2 will also enable them to reset the gears within the ABS pump and preform diagnosis on elements with the ABS. The alternative is to get out an Volt Ohm Meter and start checking everything in the ABS system from the wheel sensors to the connecting cables, the relay(s), and even the brake switch on the car. Many times items that are subject to wear and tear such as the brake light switch and the wheel sensors are those most likely to be at fault. However, the scan tool saves you from this drudgery and points the technician to the difficulty. I'd go the scan tool route as I have tried the other with no result and found that after I purchased a Tech ! scan tool the problem, faulty brake switch, was made apparent quickly.

Abs light came on


Dear, Instances like this happen if the abs sensor has gotten clothed by dirts/ dust.will simply recommend you take the car in for a scan which will help you in knowing the actual thing that must have gone wrong.

The brake pads might have gone flat too and you might have a look at the master brake cylinder too.

Please act fast on this even though it does not affect the transmission of the car engine in any way at all.

Good luck and remember to rate this solution.

Abs light is on and want to find out why is this a wheel sencer or could it be the abs pump this also turns off my allwheel drive


the abs light is tripped by any computer-recognized problem within the abs system. a wheel sensor tends to be the most common cause of an abs light. while the light is on, the standard brakes function normally but the abs system is completely bypassed. the best way to diagnose this is to plug the vehicle into a code scanner. any decent shop can perform this service, or you can purchase a scanner at an auto parts store or online. if you do go that route, ensure that the scanner you purchase specifically can interpret abs codes

ABS brake module sounds like a motor running and won't stop unless battery is disconnected. what is fix?


I would pull the fuse for the ABS hydraulic pump and then put it back in and see what happens. Don't ever recall a pump running. Dealer may need to hook up scan tool for diagnostic fault codes, DTCs.



Principles of Operation
The ABS control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.
The ABS control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.
The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; normal power assisted braking, however, remains.
Inspection and Verification — Scan Tool Communications Check
  1. Verify the customer concern by carrying out the Drive Cycle Test.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

ABS


You may have a wheel sensor or sensor ring damaged or defective at the one of the wheels, that will cause the ABS to think a wheel is locked up and give the problem you have. To disable the ABS remove the fuse or relay, I would not recommend this route, ABS can save your life and those you love in a out of control situation, SUV's are very prone to situations that ABS reallly saves you.........
