Yes, thanks (codes were even included in the leaflet of the reader I bought). I was hoping to get something more precise about the possible cause out of the codes. I'm running out of "cheap" options: next monday I'm having the IACV and PCV valves checked. MAF is clean, vacuum system (including gas cap) seems ok, coolant temp sensor works fine, no sign of ruptures in the exhaust hoses... If the valves are ok, I fear I'll have to check ignitors and/or fuel pump/filter...:cries: :(

Today I managed to question the ECU via the code reader, and I got P0174. Hope this will give another clue. Thanks again!

Thanks for your reply. Unfortunately the gas cap is really tight, and the lights keep returning in a while after they've been resetted. Today I received the code reader. Will be adding more info as soon as those *&$£ lights come out again.

Hi guys, need your expertise on this side of the Atlantic. I'm experiencing the notorious VSC+ENGINE warning. Car's performance is absolutely nominal (2001 RX mark 1 with 88000 KM). So far I've had the spark plugs changed (they were almost due, anyway) and I've checked the vacuum lines (fuel cap, hose behind filter box and so on). Unfortunately I'm unable to provide the 4-digit error codes: my mech's system will "translate" them on the fly (what we get is ECU-SERVICE 3, ECU-SERVICE 7, LEAN FUEL/AIR MIXTURE, on both banks). I've ordered one of those cheap readers in the UK, but it's still in the mail). I'd be grateful for any advice regarding what to focus on next (MAF, lambda sonds, fuel pump/filter, you-name-it... ). My mech (NOT a Lexus mech) says that he would bet on something related to sparks (wiring? coils?). I'm a bit puzzled, because that would mean that something "electric" is wrong on both banks at the same time: possible, but unlikely. My last hope would be Lexus official, but it's quite a long way from where I live to their shop. Many thanks

Thanks folks. The thing seems to behave, lately. However I'll take your advice and see the Lexus guys.

Hi everybody: I'm an Italian member of the UK chapter of LOC, and I'd be grateful if you could provide some advice. Here's the story a of a very stupid guy: was waiting for wife and kids in the car (rx 300 mark I) and I thought about going through the menu of the sat nav, just out of curiosity. Please notice that unfortunately I don't have the instruction manual of the dvd sat nav unit. The last option of the menu is something I would translate in English as "calibration" or "setting". Obviously, I thought to give it a try... cry.gif From then on, the sat nav has become inaccurate: it just seems not to pick up the correct position of the car. I've tried this option several times by now, but I'm having troubles, also because of the lack of instructions. First of all, I assume you have to be still to caliber the unit: is it so? And just how long does it take? I've been waiting for 4/5 minutes, but the (for a reason or the other), I always abort the operation (also because it's not really easy to park an RX in the middle of a crossroad so to pinpoint the correct position...). And what about the following option concerning wheels? Is that to let the system know the size of the tires? Please, please help me! The nav was working like clockwork before, I just can't believe I did this! cry.gif
