HELP!!! I have just bought an 04 plate Landcruiser a lovely car BUT it has a highly dangerous fault. Very occasionally when driving round a slight bend it bleeps and immediately applies a front brake fully, locking it up at 50mph and veering over uncontrollably. It has just had a full Toyota service and an MOT. The local Bosch service centre say there are no stored faults. On a 100mile drive it did it three times and I nursed it home in trepidation. Sorry but I have no confidence that it is a simple fix Any ideas anyone???

Agree Steve, does sound like abs, but as far as I'm aware there is no audible warning on the system, just a dash fault warning light.
Bodgy, do you have access to Techstream or similar, to see if any fault codes are stored ?

it has just been serviced by Toyota before I bought it 3 weeks ago. I took it to Bosch service agent and there are no stored faults. It would seem to me that it is an EPS fault as this is what it is designed to do but obviously not like this. How about a yaw rate sensor fault or steering angle sensor. I have no confidence that a garage will fix this but the thing is a death trap as it is

What model/series is this 2004 cruiser ?
As it has recently been serviced and I assume wheels off to check the brakes, I would check the wiring/connectors to the wheel speed sensors.

it is an LC4 D4D but would this fault not show on the Bosch plug in or the MIL?

One would assume so, but have no knowledge of the Bosch reader for a 2004 lc4 ?
Try posting on the correct forum specific for your 120, there are more knowledgeable members on there, that may not look here.

That to me sounds like your stability control is kicking in , the toyota dealers should have the knowhow to get to the bottom of it if it is an electronic fault . But have you checked the obvious items that could trigger the stability control in kicking in like front or rear anti roll bar drop links snapping or being loose , or front or rear upper or lower control arms or camber bolts broken or loose ,

Hi TonyC and Traction man, Apologies for not replying but I am not good with this and my computer would not let me reply as it said there was a virus. Thank you both .The update is that the Toyota garage tells me the angle sensor is not outputting and are going to change it . But I have looked on Google and the fault I have is rare but everyone else who has had it (not on an LC) says it is a yaw sensor problem as it does not fail safe and is the only sensor that can apply the brakes individually. They all say disconnect it. I have had the car 6 weeks and it drives beautifully and this fault only happens about twice in 100 miles and this is why it is so dangerous, if it happened on a motorway it could cause carnage. In my 76 years on the planet I have never been so scared to drive a vehicle and believe me I have driven some junk.
