Step 1: Turn on the vehicle. Step 2: Find the ESP/ESC Off button. This is usually denoted by the symbol of a car with swerving lines coming from the rear tires above the word "OFF". Step 3: Press and hold the button for 5 seconds. Step 4: Look to see that the symbol has appeared if it was not there already. Step 5: Power down the vehicle
3) Check the Stator Ring. The ABS wheel sensor works together with the stator ring to monitor wheel speed rotation. If the stator ring is damaged, it can cause a malfunction of the ABS. Check to ensure the stator ring is not damaged or dislodged, resulting in missing teeth activating the ABS light.
The ABS, ESP, BAS, and Traction lights come on primarily because of a faulty wheel speed sensor. If you replace that sensor, all the lights will go away. Although sometimes matters are not that simple. Other potential reasons include wiring issues, faulty steering angle sensors, and the failure of the ABS module.To summarize, here are 14 reasons why the ABS and traction control lights come on: ABS module failure; Computer issues; Blown fuse; Dysfunctional wheel-speed sensor; Low tire pressure; A defective steering angle sensor; Low brake fluid; Faulty steering rack; Defective pump and valve; Bad wheel alignment; Dirt and debris; Low battery voltage
1. Faulty ABS speed sensor The ABS control unit receives data regarding each wheel's speed from the wheel sensors. When one or more wheels begin to slide, the ABS control unit monitors this data and makes the required adjustments.Dirty tone ring Bad ABS module BRAKE light: Low brake fluid Low brake pads Parking brake set Any ABS fault (illuminated in tandem with ABS light on certain vehicles) Depending on the year of the vehicle, most ABS codes can be read by OBDII-based diagnostic tools on '96+ vehicles.
The wheel speed sensors (ABS sensors) must have seen a bad signal for some reason, this can sometimes be caused by a bit of dirt or a piece of rust from the hub sticking to the magnetic tone wheel which disrupts the signal briefly and flags the warning light. Low battery voltage, Damaged wire harness, Dirty ABS wheel speed sensor, Bad brake light switch. To find out why the ABS light is on, read the codes with a Volkswagen scanner via the diagnostic port underneath the dashboard on the driver's side. Let's take a look at how to diagnose VW ABS light.
