My traction control light comes on sometimes but also the rear left weel makes a funny noise as i start moving of this is not all the time but enough to bother me. am worried. also the abs light comes on sometimes! Any sugestions lads?
Bad wheel bearing.will make noise and mess with sensors,or if had a brake job done caliper maybe loose to cause noise,if a drum which most are not you have parts rolling around in it,have seen it all.
traction control and abs use same sensor,you could have debris in caliper a little pebble between brake shoes and rotor will cause issues.

That would be the "traction control light". There are a couple of times you could see it. When you first start your car, when you push the TCL button or when there is a problem with it. You should take it to a qualified machanic and have it checked out or you can verify what I have told you in your owners manual and then take it to a qualified mechanic.
The traction control will signal when there is a difference in speed of wheel rotation from one side to the other. Sometimes an Emergency brake can come apart inside the drum and jam a wheel.
A worse case condition would be a stripped differential gear on the axle shaft. The wheel sensors may pick up the difference in rotation of the remaining shattered parts.
Only a few things to do to see how bad stuff is. Elevate both rear wheels, put transmission in neutral and try to move rear wheels. If 1 does not move, it is either jammed inside the differential or jammed
out in the brake drum.
Try getting jammed side brake drum off. If still jammed, the differential cover needs to come off.
These trucks are known to have problems with the front wheel speed sensors that control your 'traction control'. The traction control is actually applying your brakes. Thats why when you turn it off, You can move with no problems. The only way to really know this for sure is to take it to a repair shop and have them diagnose the problem. You can always just replace the front wheel bearing assemblies (they have the wheel speed sensors built in), but that can get pricey.
Traction control only works when one wheel is spinning faster than the other it trys to even them out so it wont spin...sometimes if one of the wheels come off the ground in an uneven area or if you take a turn too fast and one wheel turns when the other one dont it is designed to operate.
I would remove all wheels and check the braking system...Is it 4 wheel disc or rear drum ?
If it has rear drums you could have a wheel cylinder leak that will sometimes lock the wheel because of fluid contamination....This would cause both lights to come on...If you find no problems
sometimes the abs sensor builds up fragments on the magnet and makes the light come on...
or if the abs sensor is not close enough to the exciter ring it will make the light come on because it will be out of adjustment.....all you do is press the sensor inward until it barely touches the ring and it will adjust itself....You can sometimes clean the magnet if it is contaminated and make the light go off ( only after you reach 6 to 15 mph. it will go off ).If it dont go off you have to buy a sensor.
Also make sure all tires have same amount and plenty of air to keep vehicle in balance/level.
sounds like the brake pads may be metal to metal, that could be the noise problem, but until u have the system tested for the trouble code that is setin the ABS modules memory when the light comes on you are guessing, the Dealer is the only one in most cases that has the scan tool to check ABS trouble codes.
VTM 4 is a traction control system designed for better traction and fuel efficiency. I'd get it back to the dealer ASAP. There seems to be a coil malfunction in the rear axle. I'd make them fully check out the rear axle in addition to checking out the coil sensors themselves. Best of luck to you! Greg
You can check out what the trouble code is by pushing and holding the information button and the up arrow (right side of instrument cluster above the radio) until all the instrument clusters light. Press the information button (last) to enter test mode. I've had an error C1234, meaning Left rear wheel sensor fault. I found the problem to be a corroded connector under the chasis just under the rear left door about 2 feet in. I had to by-pass (replace 1 wire due to corrosion at the connector.
