2011-2020 Dodge Durango ABS Light On: Common Causes and Fixes

By Core Brake Parts Tech Team — Circleville, OH warehouse

On a 2011-2020 Dodge Durango, a yellow ABS light that stays on means the anti-lock part of the brake system has shut itself off after finding a fault; your normal brakes still work as long as the red BRAKE light is not on too. The most common causes are a failed or dirty wheel speed sensor, damaged sensor wiring, or a problem inside the ABS module itself, and 2018-2019 owners should check for open recall 24V-838 before paying for any diagnosis.

What the ABS Light Means on This Durango

Dodge's owner's manual for the 2020 Durango explains that the ABS warning light comes on for up to four seconds when the ignition is turned on as a bulb check. If it stays on, or comes on while you drive, the anti-lock portion of the brakes is not working and service is required as soon as possible. The conventional brakes keep working normally, provided the red Brake Warning Light is not also lit.

ABS on the Durango is not a standalone system. The manual lists it as one piece of the Electronic Brake Control system, which also includes Electronic Brake Force Distribution, Brake Assist, Hill Start Assist, Traction Control, Electronic Stability Control (ESC) and Electronic Roll Mitigation. They all share the same wheel speed data and the same control module, which is why an ABS fault very often brings the traction control or ESC light on with it.

How the Wheel Speed Sensors Feed the ABS Module

Each wheel has a speed sensor that reads a rotating encoder, either a multipole magnet or a toothed steel ring. Bosch describes its active sensors as Hall effect devices that turn the changing magnetic field into digital pulses whose frequency is directly proportional to wheel speed, readable almost down to a standstill. The ABS module compares all four signals continuously. When one wheel's signal drops out, reads erratically, or disagrees with the others in a way that makes no physical sense, the module stores a fault code, disables anti-lock and stability control, and turns the light on.

That design means the light rarely tells you which corner is at fault. A scan tool that reads ABS codes (not just engine codes) is the first real diagnostic step; a basic engine code reader often cannot see the ABS module at all.

Common Causes, Most Likely First

1. A wheel speed sensor or its wiring

The sensors live at the hubs, right in the path of road salt, water, brake dust and heat. Typical failures are an open circuit inside the sensor, a pigtail chafed against a suspension part, a corroded connector, or metallic debris stuck to the sensor tip. The code usually names the wheel. Watching live wheel speed data on a scan tool during a slow drive shows which sensor drops to zero or spikes.

2. Damage from recent brake or suspension work

If the light came on right after a brake job, hub replacement or suspension repair, look there first. Sensor leads get pulled, pinched under a bracket or left unplugged, and a sensor pried out of a seized bore can crack. A damaged or dirty encoder ring on the hub gives the same symptom as a bad sensor.

3. Low brake fluid or a hydraulic problem

The manual notes that fluid level naturally drops as disc pads wear, and that an abnormally low level means you should look for a leak. Low fluid is normally shown by the red BRAKE light, but when both lights come on together the cause is often hydraulic rather than electrical. Dodge specifies Mopar DOT 3 (SAE J1703) fluid for this Durango, with DOT 4 as the alternative if DOT 3 is not available, and the manual says DOT 4 must be changed every 24 months.

4. The ABS module or its pressure sensing

On 2018-2019 models, a known module fault is covered by recall (see below). On any year, internal module faults, a low-voltage condition from a weak battery or charging problem, and blown ABS fuses can all switch the system off. Rule out battery and charging voltage before condemning an expensive module.

5. Mismatched tires

Wheel speed is calculated from how fast each tire turns. One tire of a different size or badly different tread depth makes that wheel look like it is slipping all the time. Dodge warns that tires of different size and type between axles can cause unpredictable handling; keep all four matched.

Recalls That Can Turn On Durango Brake Lights

Check your VIN at nhtsa.gov or with a Dodge dealer before paying for diagnosis. Recall repairs are free. The campaigns below come from NHTSA's recall records for this generation.

The booster recall matters for warning lights because the Durango manual states that a booster problem can be detected by the ABS/ESC system. In that case the red BRAKE light stays on, the ABS pump runs when you press the pedal, and you may feel pedal pulsation on each stop.

The Fix and What to Replace at the Same Time

Once a scan tool names the wheel and the fault type, the repair is usually straightforward:

• Sensor signal fault at one wheel: clean the sensor tip and bore, inspect the encoder ring and wiring, then replace the sensor if the signal is still bad. Replacing the hub is the fix when the encoder ring is built into it and damaged.
• Wiring fault: repair the chafed or corroded section and re-secure the harness in its clips so it cannot rub again.
• Hydraulic fault: find the leak before topping up. Leaking flexible brake hoses and seeping brake calipers are the usual suspects, and the system must be bled properly afterward.
• Module fault: recall work first on 2018-2019 trucks; otherwise the module and its programming are dealer or specialist territory.

If the wheel is already apart for a sensor or hub, it is the right time to measure pads and rotors. Worn pads lower the fluid level, and heavily scored or warped rotors add their own pedal pulsation that is easy to confuse with ABS activity. For this platform we carry a front ceramic brake kit with rotors and pads for the 2011-2020 Durango and Grand Cherokee, plus separate brake pads and brake rotors if you only need one or the other.

How Hard Is the Job?

Reading codes and checking fluid is driveway work. Replacing a wheel speed sensor is usually one bolt and one connector, but seized sensors in salt-belt trucks can take penetrating oil and patience, and the harness must be routed exactly as it came out. Hub replacement is a moderate job with a large axle nut torqued to the value in the factory service manual. Hydraulic repairs need a correct bleed, and some ABS bleed procedures require a scan tool to cycle the pump. Module replacement and programming are best left to a dealer. After any repair, clear the codes and drive the truck; the manual notes that if the ESC light stays on after several ignition cycles and several miles above 30 mph, the fault is still present and needs a dealer diagnosis.

Frequently Asked Questions

Is it safe to drive my Durango with the ABS light on?

Normal braking still works if the red BRAKE light is off, but you lose anti-lock and, usually, stability control. Stops on wet or icy roads can end with locked wheels, so drive gently and get it diagnosed soon. If the red BRAKE light is on too, have it checked immediately.

Why did my ABS and traction control lights come on together?

They share the same wheel speed sensors and the same control module. When the module sees a bad wheel speed signal it switches off every system that relies on it, so both lights come on together.

Can a bad battery turn on the ABS light?

Yes. The ABS module needs stable voltage, and a weak battery or charging fault can set codes. Test the battery and charging output before replacing sensors or modules.

Will a brake job turn off the ABS light?

Only if the brake problem caused the light, such as low fluid from a leak. New pads and rotors do not fix a sensor or module fault, and a careless brake job can cause one by damaging the sensor wire.

Does my 2018 or 2019 Durango have an ABS recall?

Many do. NHTSA campaign 24V-838 covers certain 2018-2019 Durango and Grand Cherokee models for an ABS module fault, and it replaces the earlier 22V-426 remedy. Enter your VIN at nhtsa.gov or call a Dodge dealer to confirm.
