ABS and Traction Control Light On

translated top English poorly

2005 CHEVROLET EQUINOX
CODE C0276 SOMETIMES GIVES CODE CO035 LEFT SPEED SENSOR
BUT I CHECKED SENSOR IS OK BUT REPLACE HUB WITH SENSOR.CIGUE(check) CODE C0276,
DELETE AND CIGUE(check?) SENDING C0276 AND ABS, BRAKE AND TC LIGHTING LIGHTS
---------------ANSWERS------------------------------

LEARN THIS ABOUT ABS OR TRACTION CONTROLS
ABS MUST BE HAPPY OR TRACTION CONTROL FAILS OR GOES OFFLINE ! THEN
AND RULE 2 IS ACTUAL BRAKES, WE CHECK BRAKES ACTUAL FIRST!!!!
NO ACTUAL BRAKES WORK THIS OLD. 18 YEARS WARN OUT PADS
OR BAD CALIPERS.
NO COMPUTER CAN HIDE BAD ACTUAL BRAKES
IT CAN COMPENSATE FOR 1 SET OF PADS SAY WEAK.
NO GREASE ON PADS.
BAD ROTORS(WARPED OR OMG WORSE CRACKED)
BAD PADS , WE INSPECT THEM. EYE BALLS ON THEM .
BAD CALIPERS. , PISTONS BAD OR SLIDER PINS JAMMED. (BOTH ARE DANGER TO LIFE AND LIMB .
WHAT YOU ALSO FAILED TO DO IS SCAN THE ABS IT SELF
THAT TAKES ABS SCAN TOOL.
BE SAFE !!! SALUD

Rotors could be one problem.Check fluid level.Who did the brakes.Abs is sensor which is in hub bearings .Could be bad.

Have a competent mechanic scan the codes in the ABS control. A common fail point of the 2005 Equinox is the wire harness jumper for the drivers front wheel sensor. This is a foot and a half long jumper that connects the wheel sensor to the engine compartment wire harness. It is rigidly held in place by a couple of plastic stays that create a pinch flex point just beneath the lower stay where wheel turn moves the wire against this rigid point. After about 60-80k miles, the wire begins to break down in the insulator and false wheel speed readings are read as false wheel slip indications while the ABS system tries to modulate brake pressure. This modlation creates the grinding feel. After an amount of time, the ABS computer "recognizes" this as a fault and shuts ABS and traction control off since both systems use the wheel spin input, and the dash lights light.
Although this is a pretty pricey part at a dealer, a genuine Delco replacement part can be found online often at a much more reasonable price.

I personally never have had one braking issue, in 47 years
of doing brake work,on any vehicles

That said & not to write book here

The brake work & choice of friction material
(brake pads) was not done correctly

Very few shops remove rust from anything
Rotor mounting surfaces,wheel hub surfaces,
calipers,caliper sliding surfaces,pad siding surfaces

Then they use no lube, so pads can move & release

They don't use MFG Specific & quality pads

A proper professional job would go for at least
$300.00 for front or back,just 2 wheels

Rotor machining is critical

I think your OEM Rotors that were machined, most likely
were okey new & not a good grade of Chinese Steel to
be machining

CHECK WHEEL SPEED SENSOR CONNECTION.IF ALL IS GOOD.PROBLEM COULD BE FAULTY WHEEL SPEED SENSOR.

they are called wear indicators time to replace your brakes before they damage the rotors

The rotors are warped, need to replace them, also when the wheeles are put back on, the lug nuts need to be tourqued down to the specifications for that car, or the new rotors will warp again.

make sure u didnt break a wire, there are sensors on the brakes, make sure theyre plugged in

You have a bad sensor at one of the tires that need replacing that operates ABS and traction control. If you take it in to a shop it will run $130 but they can find which sensor is causing the problem. But if you do it you might have to replace all 4 sensors to make sure you got the right one. Every hard to diagnoses. Its better for the shop cause they can get electrical read outs for each sensor.

have to ask is the relucter for the abs sensor on the axle or rotor
