VSC, ABS, Brake & 4wd lights on - Help!!!

Hello all,
I have a 06 Sport V6 awd with 257k miles and the VSC, ABS and Brake lights went on intermittently, until recently the 3 lights have been on after about a 1/2 mile drive upon startup. After throughly reading all the threads on this forum, I found out that the culprit is most likely the wheel sensors. So I replaced the 2 rear sensors and put in a k&n air filter at the same time.
Now there's 4 lights on...VSC, ABS, Brake, and the 4wd. All 4 light up right away after startup now, whereas prior to the sensor replacement and k&n air filter, the 3 lights (VSC, ABS, Brake) would go on just after a 1/2 mile drive.
Also I can't reset these 4 lights even with battery disconnected for 15+ minutes and stepping on brake petal (to drain all energy). I clicked back on the older wheel sensors and swapped back the old air filter(non k&n), and made sure there were no loose hoses/connectors on/near the air filter/throttle housing. I'm a bit stumped now. There are no codes on a OBD II reader (simple non=ABS). I've driven about 130 miles after and lights are still on. Even started engine without fuel cap without any luck. Maybe I need to drive at least several tanks for lights to clear? Any thoughts or suggestions would be greatly appreciated. Thanks all!

To determine the cause you need to read the Skid Control ECU codes either with an All Codes reader or the jumper explained in post 2 here: https://www.rav4world.com/forums/99-...lained-16.html
What I do is clear any codes using the tap-the-brake 8 times as described below the fuse box picture and see which come back first.

It's the pedal (or the handgrip) on the right!!

Hi Dr. Dyno,

Here's my findings with a jumper in the 4 & 13 of the OBD:

airbag = 1 3 2 5
p/s = 4 1
vsc = 4 3
abs = 1 1 3 3 4 9
4wd = 9 6 9 9

My question is, how do I interpret the numbers that are more than 2 digits? I read through the "BC-62 BRAKE CONTROL – VEHICLE STABILITY CONTROL SYSTEM DIAGNOSTIC TROUBLE CODE CHART" but can't seem to interpret the code. Can you help. Thanks again in advance.

Ok a quick update. I just reset the codes (via jumper in 4/13 of obd, key to on, and brake 8x's within 5 sec) and took the Rav for a quick drive and found a different set of codes except for the VSC:

airbag = 3 2, 3 5, 3 7, 5 1, not 1 3 2 5
p/s = 4 1 & 4 2
vsc = 4 3,
abs = 3 3, not 1 1 3 3 4 9
4wd = 9 6. not 9 6 9 9

I may use my friend's obd reader which can read ABS and SRS codes...

OK, ABS code 33 means Right Rear Wheel Speed Sensor.

VSC 43 means Acceleration Sensor (yaw sensor) Stuck Malfunction.

P/S 41 and 42 are ECM communication error and Skid control ECU communication error.

SRS 32 is Occupant Classification System Malfunction

SRS 35 is Seat Position Airbag Sensor Circuit Malfunction

SRS 37 is Driver Side Seat Belt Buckle Switch Circuit Malfunction

SRS 51 is Short in Driver Side Squib Circuit

4WD 96 is ABS Malfunction

I'd recommend checking into the wheel sensor. Even new ones can be affected by rust making the gap wrong. Then reset the codes.
It's my experience that several codes can exist but not set any error lights so just fixing the 33 may keep them off.

The SRS codes may be covered under warranty. Honda replaced one of my seatbelt switches that way under a lifetime safety warranty even tho the car had 200,000+ miles. And since you didn't say the SRS light was on you may not need to do anything.

Ok here's an update:

I replaced the right rear wheel sensor and thankfully the 4wd light went off, but the other 3 lights remained on. I ended up purchasing a OBD/ABS sensor and then scanned...the code was for a faulty stop light switch, so I replaced it with another...this time a Beck Arnley 201-2337 which fixed the issue.

I forgot to mention in my original post, that one of the first things I did was I cleaned the contacts on the stop light switch...still was the same so I replaced it with an OEM Toyota one, but it ended up being faulty. So that said, the original right rear wheel sensor was good to begin with. Lessons learned: to make sure replacement stop light switch is good. Also investing in a OBD/ABS sensor is a good investment. I purchased an Autel MaxiLink ML619 for around $109.

Thanks for everyone's feedback...much appreciated! It will be nice using the cruise control again.

Bad news. VSC, ABS and Brake lights came back on after about 2 miles of driving. The ABS codes from the OBD reader is still:
c1223 (malfunction in abs system)
c1249 (open circuit in stop light switch output)
I'm wondering if the second replacement stop switch is bad. Any thoughts? I may try a third stop switch replacement.
