Recently the speedo and tachometer have locked on 32kmh and 2200rpm . Also the digital odometer/tripmeter are no longer working, nor is the alarm that alerts you that you left the lights on. Any suggestions on a remedy please ?

A POR (power off reset) may help with some of it - aka disconnect
battery leads for 10 mins
