Flashing 4WD Lo and VSC and Engine warning lights


Recommended Posts

hi everyone. i have a 2010 Prado Kakadu, diesel. about 6 weeks ago I had to get a new battery. two days later I started having all of the problems with the flashing warning lights. I would have a bit of trouble getting the car started and then the lights would come on. sometimes they would stay and sometimes not, but whenever the car struggled to start they came on.

mechanic payed around a bit and we had about 6 weeks without. a few days ago, same starting issue and same lights back on.

im really interested to know if anyone has had a definitive answer. we have electric brakes fitted but no other accessories, other than the standard fitted in the car.

I haven't had loss of power issues (yet) but its really frustrating, particularly as we are thinking of selling later this year as we don't need the car for towing anymore. i can try to sell with this going on.

any suggestions????

I once had a 120 series Grande. The override brakes on the boat trailer crushed the trailer wiring. This caused the 4 lo, VSC, traction, etc. lights to come on. At the time I didn't know this was the trailer wiring's fault as the lights were still on long after the trailer was parked in the shed.

Toyota dealer took a few hours of reading to realize that fuses were blown and the computer had to be reset.

So check there is no short circuit of your trailer wiring & check that there are no blown fuses. As mentioned in previous posts, you can fix the problems that cause the lights to come on, but you still need to remove certain fuses to reset the warning lights.

Thankyou all for posting i seem to have solved my problem( My auto elect has at least solved it.)


I took my car down to have a new battery put in , when he had done this he tested the voltage between pos and neg 12.3 volts


then checked between pos and engine earth 14.4 volts


installed new earth from neg to engine block and problem seams to have
been fixed YAHOO who would have thought this would have caused the drama

Thanks

I have had this problem with my 2010, 200 series as well but only really gets noticeable when I am towing my van. Completely looses power and blows lots of smoke, also uses a lot more fuel. Have had it back to Toyota dealer this morning they say it is the MAP sensor and seldom fails so none in Australia have to wait for part to arrive from Japan, then may be other faults but can't test until the MAP is replaced.

Hi Guys

I am new to the site, but thought I would contribute, after getting the same warning in my 2009 VX TTD, just recently.

The "check VSC" warning came up, along with flashing 4 lo, ABS & traction control warning lights. In addition, I also had trouble starting the vehicle, and couldn't get it out of park, when it did start, ( needed to use the manual override button). I didn't have any loss of power, and I could engage 4 lo, but was uncomfortable, whilst in the bush, with the family, as I didn't know if I was going to get out.

I checked all batteries, both car & remote, checked fuses, relays etc. - all were ok

In the end, I found it was the brake pedal switch - it was faulty. The tell tail sign was the stop lights, flashing or not coming on when the brake pedal was pushed - I wiggles the switch and all warnings disappeared.

I took it to my friendly mechanic,when I got home, who checked the error codes, and it showed the same, plus other errors - he reset them, and all appears ok at the moment

Will keep you informed.

to taxman. 

            after a yr of it always coming on and being stuck in high or low in vic alps. thankyou very much. removing fuse 3 in engine bay solves problem instantly and gets you straight back into 4low or vice versa. much appreciated after many frustrating times out on the track.

I have a similar problem with my 2009 VX turbo diesel Landcruiser. Have had a scan done which has shown a P004B DTC. ( Turbocharger Boost Control Solenoid 'B" open circuit).  Occurs under heavier acceleration resulting in engine going into Limp Mode with loss of power. Usually clears itself overnight. However if I actuate the Cruise Control as soon as I start the engine it does not occur under normal and heavier acceleration. Mechanic advised that I need to replace the Turbocharger Electronic Stepper Motor/Actuator "B" Bank.  Booking in vehicle to have this done this week. Will advise outcome.

Thanks for that information Cleo. I will certainly ask the mechanic to check that out and other possible wiring issues before he commences replacing expensive components.

Hi all

I have had this problem in my 2010 Prado and ive  have a engine data scan it puts up a code P0400 which is EGR blocked or outside EGR values , if you are experiencing this your EGR may be blocked and have to get it cleaned .

I have a Landcruiser 200 series V8 twin turbo diesel. I have had this same problem a couple of times. I set the trip meter at the neutral mark I. E. No numbers and turned off the car. Came back a few minutes later and turned on, and presto the lights had gone off. The trip meter set itself back to the mileage setting and not where it was when it was turned off.

Gentlemen. Been reading your posts. I have LC200 V8 Petrol and also have had the same issue for years!! Always been when towing and ambient temp was high. 
toyota say it’s Catalytic Convertor, but they really dont know. Firstly they said it was MAS, but it wasn’t that. They also saying could be transmission overheating!!

Anyway, I think it is voltage related, but really, NO ONE KNOWS!’
