So I had my vehicle (02 TL-S 183k) scanned at autozone with cheap obd2 sensor with no codes coming back. Took it to another place to have codes ran. They gave me this list of codes.

16-01 RR speed sensor malf.
25-01 Yaw malf
41-01 RF wheel lock
47-01 LF apply sol val malf
51-01 ABS plug motor malf
53-01 ABS pump motor relay short
64-01 sensor supply volt malf
72-01 modulator unit malf
81-01 ABS control unit malf
83-01 ECM to PCM module relay malf

Prior to the scans my battery was leaking fluid. Currently in the process of replacing all ABS wheel sensors. New battery installed.

I have been trying to search for fixes, but I can't seem to find any of these codes. Am I missing something?

ABS codes do not erase even with out a battery present.
If I were you go back to where you got it scanned and ask to delete all the codes, then wait for the ABS/VSA lights to come up and scan it again then go after the issues.

After reading other member problems and their codes. These don't even sound right for our vehicle. Just a thought....

These codes must be from Previous faults, you must start fresh with no codes, otherwise you'll be throwing Parts at it.

Is the "CEL" presently on ? If so, then try clearing it by removing the clock backup fuse located in the passenger's side interior fuse panel. If it comes back on, have the codes read again and post them here.

If the "CEL" wasn't on and your 2nd place found the codes which you previously listed, they apparently had the special reader for ABS. Did they tell you what the problem may be ? Could be old codes stored, IDK. Maybe the car had a faulty wheel sensor replaced at some time ?

AS EricUa5 said first thing is to get the codes cleared and start from there. You probably will have to go to a shop to get it done but worth it in my opinion, for your safety, your pocket book and piece of mind. A shop might be able to do it for a very small fee.

No CEL light.

yeah it seems a majority of the codes relate to ABS. As stated earlier, in the process of switching out all ABS sensors after my wrong parts from autozone gonna grab some OEM senors and put those on prior to getting codes ran again.

Nicks2001tl

Typically when the abs system is repaired the codes will go away. Unless they are somehow stored. If you do the proper repair and they are still there than you are going to need to clear them.

3.2TLc

Yeah, have the stored codes cleared if ya had previously done work and then see if they come back. Don't randomly replace parts unless you're sure that the displayed codes are recently related to the ABS system.

any luck with 53-01 pump motor relay stuck on? i have had this on for a while. sometimes the abs activation and deactivation works.(vsa button) 90% abs and ! light on 10% off and works fine.

Kind of lost motivation with this. After replacing all 4 sensors the lights stayed off for a while. After a few days they came back on. Then when it rains they turn off. After roads and car is dry they come back on. Sometimes while parked on an incline/decline they turn off. So you can see why lack of motivation. Lol.

I don't believe those codes are for our car. Most of the time, code must start with a P0xxx

3.2TLc

ABS codes may be different, IDK ???
But, a special reader is required to pull them.

ErickUa5

P codes are Power train codes.
ABS codes are manufacturer specific.
Please check out post #2 and #4 for more info.

Kennedyhuynh did you delete the codes after replacing the sensors? Soon as the light comes back on check again.
These codes can be set by anyone poking around under the hood or pulling fuses with the key on.
