Toyota—LEXUS LS460 and LS600hL—Steering Control ECU Replacement
What are the defects?
On certain Lexus LS460 and LS600hL vehicles the Steering Control ECU programming for the Variable Gear Ratio Steering (VGRS) system can result in the steering wheel becoming off-centre by a maximum of up to 90 degrees under certain limited driving conditions such as when conducting a U-Turn or accelerating quickly following a sharp turn. If the driver has fully turned the steering wheel to full lock and then very quickly attempts to turn it back to the centre position, the steering wheel may temporarily become off-centred before automatically returning to the centre position within 1-5 seconds.
