Apologies for the late response. Ensure you are using proper method for pulling blink codes. The steps to pull blink codes is different for every manufacturer, as are the diagnostic codes. For example if I were to pull active codes from a Bendix unit, I would apply constant power to the AUX circuit and cycle brake light power 3 times to get active codes. But if I was pulling codes from a Haldex unit I would do the opposite for active codes...Apply constant power to the brake light circuit and cycle the AUX circuit 3 times. If you are using the correct method to pull blink codes and still can't get the ABS light to blink, you could have a defective ECU. Also check to see if someone has mistakenly wired the ABS light straight into the AUX circuit (blue wire). I've seen this a lot. Hope this helps!
@@fleetrepairsolutions6372 dude thank you, I'm a apprentice I've been doing a little truck work but mostly trailer work and you teach me a lot. Keep up the videos they are great!
Thanks for the complement, happy to help! To pull blink codes from a Wabco unit with the ABS light on, you need to power the AUX circuit for 1 second, power off for 1 second, then power back on. No brake light circuit activation with Wabco.
Thanks for sharing! Good information to know
You have great content
Hello my friend
Love your videos!
I'm getting blink code 11, by any chance can you make a video for that code?
What do you do in situations where the abs light just stays on? And is not giving a blink code, but just remains on

@@fleetrepairsolutions6372 for a WABCO module do you do trailer aux cycle 3 times? Anything with brake power ?
