Bring it back to the repair shop that did the initial repair and have them complete this repair. There is something wrong. They have to reinspect their work and check the ECU for loose wiring and determine whether you need a new ECU.

Abs light came on


What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control. How this system works: Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid. Common reasons for this to happen:
  • ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
  • Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working. What to expect: A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. How important is this service? It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

ABS light and traction light and no cruise control


how on earth would the blind know what is wrong.?
scan it? yet?
btw, newer cars cut cruise feature for any signs of danger.
new laws...
the traction needs ABS to work ,so forget that and fix ABS.
ABS needs 2 things to work , brakes and ABS.

so if brakes are bad, then ABS will get upset.
after all, if it cant brake right, how can the puter save you?
if brakes are known to be ok (inspections work here)
but in this case it was BREACHED by you, with out reading the book first.
then scan the ABS. (omg? code for dead sensor?) nah, you caused it..
easy

ABS resets every key on. so...
my guess, if ABS was happy before your actions( you never said)
then you got air in to the system. and failed to follow the FSM instructions on bleeding brakes, in ABS car.

front caliper, did you block the hose with cap, so it didn't allow air to the modulator? oops... never just let them drip... or . max pain.
bleed it again, (using any or all 5 ways to do so, bleeding is skill thing) (many modulators can not just be simply bled)

now Ill quote the 2012 fSM for you , under brakes

Data: -----------------------------------------------------------------
ABS Brake Bleeding
STANDARD PROCEDURE - ABS BRAKE BLEEDING

ABS system bleeding requires conventional bleeding methods plus use of a scan tool. The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system.

Perform base brake bleeding, (Refer to Brakes - Standard Procedure)(Refer To List 1).

Connect scan tool to the Data Link Connector.

Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then ABS BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed.

Perform base brake bleeding a second time, (Refer to Brakes - Standard Procedure)(Refer To List 1).

Top off master cylinder fluid level and verify proper brake operation before moving vehicle.

ABS LIGHT AND TRACTION CONTROL LIGHT STAYS ON


ABS = Anti-lock Brake System.
TC = Traction Control System (Engine Control Module).
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS & TC Electronic Control Units (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.

I suspect bad brake pedal switch, but you should scan the ABS & TC ECU's.

I have a 2002 VW New Beetle. The ABS light has come on and there is a chiming beep and the ABS light flickers. What could be the problem?


ABS - Anti-lock Brake System.
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car.

After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.
ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.

For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.
tdisline_703.jpg


ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.
The ESP system means the Electronic Stability Program. ESP system includes the ABS system.

Abs light came on and a tc with line through it came on


when you have antilock "problem " on this vehicle you automatically get t\c light, I fixed this problem for a friend when the tire rubbed through one of his abs sensor cables .. just re-connected it don't spend $500 at a "RELIABLE" shop if you can fix this yourself....they will never tell you how easy it might be to repair!!

Transmission Traction "Off" light stays lit with Traction button


The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.

The traction control gets its information from the ABS system, so a faulty sensor reading will automatically shut down the traction control system.

It is common in this vehicle for the sensor to malfunction!

Brake system warning
Momentarily illuminates when the
ignition is turned to the START
position. Also illuminates if the
parking brake is engaged. If the
brake warning lamp does not
illuminate at these times, seek service immediately. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON
position. If the light remains on,
continues to flash or fails to
illuminate, have the system serviced
immediately. With the ABS light on, the anti-lock brake system is
disabled and normal braking is still effective unless the brake warning
light also remains illuminated with the parking brake released.
