ABS Repair Completed, But OBD Shows 0 DTC – What's Wrong?

[Fireair]

Hello Everyone,

I'm hoping to get some advice on an issue with my 2016 Ram 1500 Hemi V8. A while back, the check engine light came on, and my scanner pointed to a problem with the ABS sensors. I went ahead and replaced all four ABS wheel sensors, then reset the system, feeling pretty confident I had solved the problem.

However, when I went for my inspection, everything passed—except for the OBD reading, which failed the inspection. The technician advised me to drive more miles and return within 15 days, so I did just that. After putting in some extra mileage, I plugged in my Innova 3020 scanner, only for it to display "0 DTC" (no error codes). You can see the attached photo for reference.
To troubleshoot further, I disconnected the battery and jumped both cables to completely drain the system, aiming for a hard reset of the PCM and ECM. Unfortunately, even after that, the scanner still shows "0 DTC," and the OBD won't read properly.

At this point, I’m out of ideas. Could I be overlooking something? Has anyone else experienced a similar issue with their Ram, or does anyone have suggestions on what else to try? I appreciate any help you can provide!

Thank you in advance!

-James

Thats really not the best scanner. Maybe go to the local auto parts store and see what scanner they have to read for free. Using my OBD MX+ and the factory app (obdlink) will show me codes that others won't. Also ALFAOBD will also show malfunctions that maybe ondlink wont or my actron won't.
Regardless now that you pulled your battery you are going to have to do the drive cycle over again. Get on the highway and drive. If he is saying theres a code, its a 'permanent' code and needs time and mileage to clear it after the fault causing it is repaired.

UPDATE:

Hello everyone,

I recently purchased ALFAOBD, and it displayed one code: C2200. The details are as follows:

• Code: C2200
• Description: Antilock Brake Module Internal
• Issue: Internal electronic failure
• Status: Last test completed unsuccessfully; error is present
• Failure Warning Lamp: "On" requested
• Error Counter: 39

I performed the ABS Recirculation pump test, and I could hear the pump running. Can anyone please guide me on what to check next and how I can fix this issue? Thank you very much for your help.

This is a common problem. Most send their abs module in to be repaired. Do a search on the forum and you'll find the vendors who offer this service.

If your competent with electronics, here is a video showing what to check.

A new control module is only $220 from the dealer online. You have AlphaOBD. What does a repaired module cost???

I went to the Dodge dealership and explained my situation: I have an ABS issue with my truck. I was told the part costs around $1,500, but there are no parts available from the dealer, and there are no aftermarket options either. I feel like I'm at a dead end.
