1990 Lexus LS 400 Error Code Help?
Hi,
I have five lights that light up and I can't seem to detect the error code from the manual and online sites. Attached is the image.
The Error Lights that light up are the:
-Battery
-Emergency Brake
-Engine Coolant
-Engine Oil
-Replace Brake Light
So far I've gotten a recent oil change, refilled the engine coolant, replaced front brakes and back brakes are fine, and no signs of damaged brake light.
And the battery appears to be working, though I haven't tested it yet and am about too.
Are these combination of error lights suppose to represent something else wrong with the car? I don't notice anything immediately wrong.
I do plan to replace the timing belt soon, but I'm not sure if these are the error codes for a broken water pump or serpentine belt or something similarly related to warrant this

All those lights together does not indicate an error. Your check engine light is the only ones to throw codes and this link will tell you how to check it.

Do all these lights stay on while the car is running? If so then there is definitely a problem. The battery would most likely point to an alternator issue, oil lamp is a sensor/pressure issue, brake lights are probably a blown bulb. Or you could be experiencing the famous trunk harness issue that plagues the early generation cars.

The lights turn on and off while it's running, but this is the first time i've seen after driving it for 3 or so months.
All these lights come on in the middle of my drive and stay on or turn off sometimes.
I'll check with a mechanic about the alternator,

Do you know if the ECU has been replaced or repaired? If you're not familiar go to the thread about it, there was issues w/ bad capacitors, i.e. they leaked. That might be the source of your issues...
