Random Problems

Recommended Posts

My brother has a 91 ls400 and the check engine light has been on for a while, he took it to autozone to get his codes read and they told him that it was 95 or older, so they couldnt read his codes..... is this just crap or what?.... and when i was driving his car, it seems like you have to press awefully hard to get the car to slow(im comparing brake feel to our sc430 and toyota sienna), he said he just got new pads, could he be in need of some steel braided lines?... hes around 160K miles, is there anything he should be looking at changing? I.E. motor mounts, new shocks and struts, etc. he has gotten a new steering pump recently, and a new retractible antenna, but sometimes it doesnt go down all the way, is there any lubricant that would help?... I have tried WD-40 and it seems to wear off after a couple days.... thats all of the problems I can think of right now...

I have tried wd40 on the antenna as well, it didnt work well at all. I have since used a lithium grease and it lasts much longer.

Autozone doesn't have the equiments to retrieve code from obd1 vehicles. You will need to replace the antena mast.

his antenna mast is pretty new, because the dealer broke it last time he took it in, so they gave him a new one.... and if autozone cannot read the obd1 codes, then is the dealer the only one who can?... and will that cost big bucks just for them to check it?

"Under your hood there should be a black cover usually located on the drivers side that says DIAGNOSTIC. You want to short TE1 and E1 with a paper clip or short wire run. When these two are shorted get in the car and turn the ignition to ON, do not start. The engine light will blink the first number in the error code, pause then blink the second number. Count these, post them here and I'm sure someone can help you out."......... I dug this up from some really old threads, is this a good idea, and will it work on a '90 ls400?

We have the lexus scan tool to retrieve the code and properly diagnost the problem. Where are you located in Tx?

Re your power antenna my guess is it's "gunked up". Try cleaning it with a clean dry cloth and gradualy it will extend and retract the full length. Re what maintenance the LS400 needs might be answered by its service records from a Lexus dealer(computer printout), also check the maintenance records book that came with the owners manual. Another option is to take it to a Lexus dealer and have them do a full inspection (125 point) that they would do for a "certified" LS400, a fairly thorough inspection. Before I purchased my '92 LS400 I went thru all the maintenance records (Lexus dealer printout) and found that it had a complete service history and was all up to date and the next service was an oil change. I wouldn't dream of buying an LS400 or any other vehicle without knowing its service history. On top of that the vehicle looked spotless and the prior owner kept it garaged night and day.
