ABS, Traction control and Brake warning lights

@ShimStack seems to only trigger these codes when my steering wheel is turned and I lose traction. Today it gave me 10 codes, 5 under ABS and the same 5 under power steering. BTW, not sure if it matters but I have already replaced my power steering rack. Rack is not leaking and fluid level is correct. I wonder if a bad abs/speed sensor cable be causing this or a bad sensor? I'm still waiting on the replacement cable to arrive.

Techstream cable can't get here fast enough!

 

Could it be this simple?

The fact you replaced your rack is definitely pertinent new information. What are the 10 codes today? Something in the system is not creating the response or feedback the skid control ECU expects. This could be a mechanical issue (loose bushings/mounts, malfunctioning solenoid, malfunctioning pump, brake line obstruction, etc.) or it could just be an electrical signal (sensor, wiring, calibration, control, etc.) issue. It has now thrown codes at startup (diagnostic checks) and constantly throws codes when the traction or stability system functions. There is a problem to find.

 

I guess more backstory would be pertinent sorry.
I had my dealer replace the rack in the summer of 2019. Also replaced my UCA uniball to delta joint as the uniballs were worn. Also I have had the occasional abs/traction/vsc lights ever since my truck got a lift years ago. I did a little research at the time and wrote it off as just an issue that people contend with when you get a lift. It started getting worse this winter so I decided to really look into it that's when I found the loose abs/speed sensor. Same 5 codes (see screenshot)under ABS and power steering

 

Stretched cable(s)?

 

I definitely want to eliminate that possibility. I could of paid dealer price and had it today but I wanted to save some cash and bought one from a Toyota dealer off eBay

 

My truck has seen a lot of suspension work over the years. I started with 5100's, then went to a heavier spring, then icons with #650, then to #700 springs. Plenty of opportunity for cable stretch.

 

Replaced both front(LH/RH) abs sensor wires, stop light sensor, and entire abs actuator unit (sport). Still getting error on startup very occasionally particularly in cold weather when I leave it overnight. If I turn ignition off and on again error goes away and abs works fine. My tire pressure was down on all four tires to 27 psi. Due to the extreme cold weather. I'm wondering if this would have caused the errors below? I filled the tires to 35 PSI and reset the TPMS sensors. Waiting to see if the error comes up again. Any help appreciated @ShimStack ? Thanks in advance

 

Sorry for digging up this old post, but I've been battling this same issue for 2 or 3 years now every time the weather turns cold in my area. I've got a 2018 Sport that will intermittently throw these same exact codes. The dash lights up and cycles between the messages "ABS Check Anti-Lock Brake System", "Brake Check Brake System", and "Pre-Collision System Malfunction". Gets real bad at times and happens almost every time I drive it, then I may go 2 or 3 days before it happens again. Once the weather warms up in the spring/summer months it'll never happen. I've taken it to the dealership once and they charged me $200 just to pull inactive codes and said they couldn't diagnose it since they were unable to get it to flash the warnings.

@ponts Curious if you were ever able to solve it?

 

Following up in case anyone ever stumbles upon this post in the future...after fighting the CEL codes described in this thread for the last few years during the winter months and recently experiencing additional intermittent issues (ex. the truck would stumble/stall coming out of first gear around 5 mph) I decided to replace the battery. For reference I have a 2018 TRD Sport that I bought brand new that still had the original battery in it, mileage is ~50k. While replacing the battery I also found that the chassis connection at the negative battery terminal wire was somewhat loose. I attribute this to the fact that I added raptor lights and used the same chassis termination point to secure the (-) lead of the raptor wiring harness, thus causing a less secure connection. I need to move the raptor light wiring harness lug onto a dedicated chassis connection but haven't gotten around to it yet.

Since replacing the battery and tightening up the chassis connection I've driven the truck for almost 2 weeks without issues. During that time it's been the coldest here it has been all season, so I'm increasingly confident that either the battery, chassis connection, or some combination of both were major contributors to my problems. Fingers crossed it continues to behave. I replaced the battery with an Autozone Duralast Gold.
