convert

Hi, im convert and owned a 2007 4x4 turbo diesel hilux for two years, About a year ago my dash airbag light occassionally came on and more recently is staying lit all the time. I am reasonably sure I caused the problem by driving over scrub because I tow a camper and more often than not its difficult to attempt a three point turn when you run into a deep washout. Has this topic been aired on the forum in the past and can anyone assist me with this? Regards frustrated convert
