Question

I have a 2000 Volvo 2.3 liter V70.I keep getting different lights on the dash.The engine light,the abs light,traction light,the transmission arrow.Sometimes the odometer goes off and the speed indicator and the milage count.I reset them with my Innova 3100 diagnostic reader and all is fine for a couple of days.They seem to appear at random without effecting car operation.I have also had the following readouts Calc Load % 19.2,ECT(Degrees C)47,LIFT BI(%)9.4 and MAP(KPA)31.
