How do I get blink codes from Wabco ABS?
The WABCO Enhanced Easy-Stop Trailer ABS ECU detects any electrical fault in the trailer ABS. Each of the faults has a code. When a fault occurs, the ECU stores the code for that fault in its memory. The code (blink code) can be obtained using the Ignition Power Activation method (described below).
What are ABS codes?
The ABS light (usually yellow, amber or orange) should come on briefly every time you start your car as part of a system check. If the light stays on, that means something isn’t working and the system has been shut down. With ABS, sensors mounted at each wheel monitor the speed at which the wheels are turning.
What are ABS blink codes?
The WABCO Electronic Control Unit (ECU) uses a pattern of light flashes called a blink code to identify specific problems, or faults, in the ABS. The warning lamp flashes a blink code for each fault that the ECU stores in its memory, enabling a technician to repair faults and erase them from ECU memory.
What are the symptoms of a bad ABS modulator valve?
The signs of a malfunctioning ABS modulator can mimic problems with calipers, brake hoses or the master cylinder. Common complaints often include pulling brakes, long stops and low brake pedal.
How do I know if my ABS modulator valve is bad?
So, when an ABS control module fails, you’ll likely notice it when you’re braking heavily. A bad ABS module can behave erratically, making your brakes lock up even under normal braking. You might even notice unusual behavior from the brakes, like random clicking noises. These can also indicate ABS module failure.
Can worn brake pads cause ABS light to come on?
To Be Clear, Worn Brakes CAN Cause The ABS Light To Come On, But It’s Not Why You Think. Your brakes and your ABS are not the same, even though they work together. Your ABS system has its own electrical control unit which is separate from your braking system, even though the ABS and your brakes work together.
What are ABS fault codes?
Common fault codes C0070: Right front ABS solenoid 1 circuit malfunction. C0075: Right front ABS solenoid 2 circuit malfunction. C0080: Left rear ABS solenoid 1 circuit malfunction. C0085: Left rear ABS solenoid 2 circuit malfunction.
What causes a trailer ABS light to come on?
During startup, when the auxiliary circuit is first powered, the ABS runs a self-check. The ABS status light comes on for 3 to 5 seconds, and you might hear the air valves “chuffing”. If the ABS status light fails to light up, blinks, or comes on and stays on, an ABS fault is indicated.
