I have a 2007 GS350 and all of the lights (Check 4WD, Check VSC, Brake, Engine Warning, etc.) are on.

I bought a scanner, hooked it up and it came back with no codes. I know the scanner is working because it came back with the correct VIN, but no codes at all. From reading this thread and elsewhere, I'm thinking it is either a fuse (how to tell which fuse) or something with the battery? Can't figure out what else it could be since the reader is coming back with no codes. Also want to make sure it is safe to drive since there are no actual codes flipped. The fact that the Brake (emer brake) light is on too makes me believe it's something electrical. Battery is less than a year old from Autozone.

Any other ideas or something I'm missing?

Alternator or battery would be my guess.

So my GS350 mentioned above with all the lights (brake, VSC, 4WD, CEL, etc.) - the battery tested out ok but alternator tested bad.

We had the alternator replaced but all the lights are still coming on. Taking it to the dealer tomorrow, but anything else I should check before taking it in? It's still coming back with no codes reported on the scanner.

I just had this situation happen this past week with my 2006 GS RWD.

The code was:

P0031
Heated Oxygen
Sensor Heater
Control Circuit Low
Bank 1 Sensor 1

10 dollar gas cap, a few days (3) of regular use and the lights/code are gone.

I made a different thread thinking it was the O2 sensors, so wanted to post in this thread in case anyone else has the same code in future.

The following post can go in multiple threads but I'll post it here and post a link in other threads if needed.

Ok, so my alternator died and I got it replaced. A few days after that, my car would jerk when shifting from 5th to 6th gear. I thought it was transmission but after researching here I decided do a ECU reset. I know I pulled and put the fuse back in correctly. However, after this, I had several issues.

1. VSC light is on with CHECK VSC message.
2. Remote won't unlock the door.
3. The unlock button on the door won't work.
4. Door lights won't come on.
5. cabin lights won't come on.
6. AFS light blinks constantly.

# 2 - #5 works fine once I start the car though.

My question...what may have I inadvertently done wrong while trying to reset ECU? How come so many things stopped working all of a sudden?

By the way, the issue with my transmission stuttering between 5th and 6th gear is still there. If this turns out to be transmission issue, I would dump the car and get a new one, however, I want the lights gone otherwise dealer won't pay anything for it. I just got new tires, batteries and alternater so I have quite a bit invested in the car already but I am willing to cut my losses if it is transmission.

Completely coincidental... there is no way a gas cap sets that code. It will probably come back again.

I have been dealing with the check engine and vsc light for about 1 year on my 2006 gs awd.

Here's my story about how I eventually got it fixed. The first thing was the gas cap which is usually never the problem just a quick fix and a reset. After doing this the light came back on so I took it to another mechanic. He told me after inspecting the car their where no leaks in the exhaust and the O2 sensors seemed ok as well. The mechanic then suggested a $2200 cat convertor replacement. I was not happy to hear this. I did not go through with the repair and continued to drive for 6 months.

Eventually I started hearing a leak in the exhaust so I took to a professional muffler and exhaust place. They notices the leak in 2 minutes and swapped the pipe that was leaking. Finally the vsc light turned off after 2 weeks and has not returned in a week. Before it would turn off once I a while but return within a day. Would suggest that talking your gs to a professional muffler and exhaust place. He even gave me a way better qoute to change the cats if iI had too around 1000 bucks which seems reasonable thank god it looks good for now

Had to replace the starter and crankshaft postion sensor.

Mine was a 2006 Lexus IS 250

The codes read out as:

Cylinder 5 misfire
Cylinder 6 misfire

Solution: changed spark plugs; used NGK Iridium ones and then mechanic reset the OBD. Mechanic also transferred the coil packs 5 and 6 from the back to the front, just in case the coil packs go bad, they are easily reachable.

mechanic also charged 3 hrs for labor so quite expensive though at $70/hour .

car now drives smoothly like new. =)


After driving for two days, check VSC has not come back (hope it'll never come back due to these cylinder misfires)

So my lexus is 220d dies after drift. I try to start it and the start just runs like ten seconds. it may start or may not. But it will start second or third time. After it starts there is no problem with the car. Works fine unless i drift it. Any solutions to that ?

2009 GS350 RWD sitting at 95,500mi. Today the "check engine light" and the "VSC/Slip Control light" came on. Car had zero difference in performance/drive/sound, etc. I, coincidently, had topped off my coolant resivoir this morning and when I did....I cleaned/wiped that front black plastic clean, where the air intake scoops are, with a shop rag and some tire shine. I dried it off pretty well, but a drop or two of the tire shine was left down in the hood latch area. Was wondering if some of that could've got sucked into an area that would have fouled up the MAF sensor or something ??

Or...did I just have my MAF/O2 sensor just crap the bed on me all of the sudden?? Any ideas? I'll drop by a parts store tonight and have them pull codes. Assuming it's a O2 sensor....is this a DIY type fix ? I've done them on my Honda's...hopefully the GS's are easy.

O'Reily's Parts store pulled codes and got... C1201 Electronic Control System Malfunction, C1241 Low or High Power supply voltage, P0101 Mass Air Flow Sensor and P0136 Oxygen Sensor Bank 1 Sensor 2


Then went to AutoZone and had them pull codes.... they came back with P0136 (O2) and P0101 MAF

So...Safe to say that P0136 and P0101 need replacing. I'm sure they both didn't crap out at the same time. Is it just that possibly one was not "quite bad enough" to trip the light but still can show on the scan?? That is what the AutoZone guy said. Crap...I should've had him reset them..then wait to see if they come back on.

I had the guy check the battery too (since some people have found that to be the source) but it's only a little over a year old/18k mi and it checked out ok.
