ABS, BRAKE, VSC TRAC, VSC OFF, ACTIVE TRAC Lighs On

[LandCruiser828]

I've read several posts in regards to all of these lights being illuminated but have yet to figure out my issue.

2001 LC with 199k miles, new to me. I knew this could be an expensive fix before purchasing if it happened to be the entire brake/abs module but I'm trying to narrow it down myself without having to pay shop hours.

Brakes and brake lights work just fine, no loss of pressure. Ive done the test where you pump the brakes 40-50 times then turn on to see how long the brake motor runs. I timed mine at 35 seconds.

Ive tried jumping the terminals in the diagnostic port to get the ABS light to flash, however, all of the lights stay solid, but, the cruise control light starts flashing. I've also tried disconnecting the battery for an hour or so but the lights remained. The battery is older and I haven't checked the voltage output to see if this could be the cause. Of note, the transmission was rebuilt about 8k miles ago and I do not know if these lights were on prior to this or immediately after, or maybe not involved with it at all.

Would really appreciate any advice or help with this!

Sorry I’m just now getting back to this!

From that picture alone, this makes me think it’s the ECU. But like you said, without ruling out all of the other things, it’s not 100%.

Do you know if it will throw any codes? Once you get confirmation that the ABS and traction control will not throw a code/communicate, that’s usually the tell tale sign it’s the ECU-simple fix with just 4 plugs and 2 nuts.

My first through was the ABS module/actuator but I was able to rule it out with a series of tests. First, with the car off, pump the brake pedal about 50 times until there’s no pressure in it. Then turn the key to the in position and see how long it takes the brake accumulator to run. I believe the normal run time is around 35 or so seconds. That gives you a pretty good assumption that is usually ok.

I haven’t had my 01 LC for a month so I’m still new to all of this. No experience with the wheel speed sensors at this time.

Keep me posted and let me know how I can help in any way.

Thanks, I appreciate that — I’ll definitely try that brake pump test when I go see it.

I’m planning to check it out Thursday. Since the seller mentioned the ABS actuator was replaced, this helps rule out one of the bigger items, but I still want to verify everything myself.

Main thing for me right now is making sure the brakes feel solid and safe since I’d be driving it a long distance right after.

I’ll report back with what I find.
