ABS, VSC TRAC, VSC OFF, BRAKE lights, alarm sounding. Brakes hardly working 2001 LX470

Hi all,

This morning pulling into a parking garage my dash lit up with the following lights ABS, VSC TRAC, VSC OFF, BRAKE as well as an alarm and brakes barely working.

I just changed out passenger side ignition coils and spark plugs. (Don’t know if this could have done anything). has this happened to anyone or can someone direct me where to inspect my vehicle. I just moved to NYC and it is pretty pricey up here to get mechanical work done.

thank you everyone

Typically, this is the brake booster motor/pump/accumulator failing. $1400+ part + installation (fairly easy DIY). You need to dump any codes and do basic brake motor tests. Unlikely that your plug/coil work had anything to do with this.

See reply #12 in the link in my signature - the brushes on my brake motor wore out and wiped out the commutator.

Sounds like a brake booster system failing as @StevenH mentioned.

If you are on any of the 100 Series Facebook Groups, there is a member Andy Lee who specializes in rebuilding them. He's got a good reputation and it fairly quick if memory serves.

Thank you for your help Steve, I read somewhere this could be due to a faulty batter. Any idea if there is some truth to this?

Check Brake fluid level.

Check Brake fluid level.

It’s full

How many miles on your truck? Typically the booster units fail at very high miles.

hello everyone - I have 2003 Lexus LX 470 232K miles

I am reading through these threads as I have a similar issue. I had the brakes with rotors done and the next day found two leaks the driveway - which I thought was oil - turned on car and for first time ever the ABS alarm, VSC VSC Off and Brake light on. Brakes low. Took it back to brake place and they said it had nothing to do with them but got codes - C0278 C0279 C1223, 1253, 1254, 1256 They are 99% sure it is ABS Module.
The oil was brake fluid. It was intermittent as I was then able to drive next day. Suggested to get an alignment so got the rack and pinion done as steering wheel was 180 degrees off. Again the Alert. Took it to my mechanic and he says it's the ABS Module. Before I invest any more money, I want to make sure that is the issue.

Thank you in advance for any input.
