Don't Replace ABS Module Before Watching This | Repair ABS Module for Motor & Valve Relay Error

In this video I explain all relevant internal circuit and components (including the relevant transistors and pins) to test and repair ABS common faults (ABS Motor Failure and ABS Valve Relay Error), so in many cases that you have these two fault codes, you can repair the ABS module and you don't need to replace it, so watch this video before replacing.
What's included in this video:
00:45 Explaining the ABS Power Supply on Wiring Diagram & the typical diagnostics by mechanics
03:30 Explaining the ABS Internal Circuit to Provide the Battery Positive to ABS Motor (On wiring diagram)
04:58 Explaining the ABS Internal Circuit to Provide the Battery Positive to ABS Valve Relay (On wiring diagram)
05:55 Explaining the ABS Module Sections
08:05 Explaining the ABS Power Supply on the Connector & Electronic Board & the Common faults on them & how to Fix it.
14:15 Finding the ABS Motor Transistor on the Electronic Board, Checking the transistor input from the main pin and output to the ABS Motor
17:39 Testing the Power Supply from the ABS Motor Transistor to the ABS Motor
18:48 Testing the Ground on the ABS Motor
20:00 Explaining how power supply will get to the ABS valves & testing the relevant transistors and internal circuit

Ironic I found this video. Actually my ABS was having faults. My mechanic first said need to buy a new one then has to be coded. Which would have cost a fortune. I told him give me the module and I'll send it to an electronics repair place I know who are really good. They fix everything from from gpus, laptops, cpu, etcetc. Sent it to them and they found it was as you rightly pointed out a power pin supply issue. They fix3it and my mechanic fitted and ran diagnostic test. No issues. Save a ton of money too! As you said anyone that has a abs module problem said do this!

Great instructional session. I have the ABS light illuminated on the dash of my '02 Chev TrailBlazer 4x4, with OBD code C0267 -- "ABS Pump Motor Circuit Open". I have good continuity at the motor connector (motor and leads good), but no continuity between the battery pin (#1 your diag.) and motor ground (#10 your diag.) on the circuit board w/ no power applied: is this a normal condition because motor relay is open when unpowered, or am I likely to find a soldering fault once I open up the control module? If I apply power to the circuit board (ignition key on), can I expect to see +12V at the circuit board ABS pump motor output pin connector? I.e., is there a way to check for a pump motor "open circuit" condition on the board w/o removing the module cover? Does the ABS Pump Motor normally run for a few seconds on every "ignition on" as a test? Thanks for the great videos!

I'm an electronics engineer (for over 30 years) and dry joints are a prevalent issue in places that have a lot of vibration etc, just like you pointed out on the +ve supply pins. My Suzuki Grand Vitara has an ABS/ESP error so I'm suspect dry joints on the circuit board is the cause.

I am told that this is inside the ABS control module but did not see it referenced in your video. Can you offer any insight as to where I can find it and possibly repair it? Thank you!

[@AutomotiveDiagnosis]

Hi my friend. It is actually located inside the ABS module and the reason for not addressing in the video is that this sensor is controlled directly by the ABS unit there is not much we can do about it. Most of the time when we have this code, we have to replace the entire ABS module.

Thanks for the excellent video!
I have a 2003 vw mk4 Golf that is not getting any abs errors or trouble codes but I cannot bleed the driver rear calliper and have diagnosed to the abs module. Looks like it could be a sticky/stuck valve. Is disassembling the module a possible way to check or confirm it’s a stuck valve? Using VCDS abs output test to check operation.

[@AutomotiveDiagnosis]

Hi there, and thanks for your comment.
It is possible to dismantle and check the valve, but as it is sometimes a long procedure so from my point of view it is better to make sure nothing else is causing this. Just one question, when bleeding the braking system equipped with ABS, we normally bleed in two steps, first of all conventional bleeding (without scan tool), then bleeding with scan tool (if that scan tool covers the function), When you do the first step, do you get brake fluid on driver rear caliper or no?

[@brentredberger9437]

@@AutomotiveDiagnosis Nothing at the Caliper. I also disconnected the pipe at the ABS valve body for that rear caliper and there's no fluid coming out even with break pressure. All the other ports have fluid so that's why I suspect a stuck valve. I've also tried actuating the valves using a magnet but couldn't hear clicking or activation. Is alcohol and compressed air the best way to try and clean? This makes we wonder how many older vehicles are on the road with this type of issue as it doesn't through an ABS code.
