Hi I wonder if you guys can help ? , I've had problems in the past with the red Air bag warning light staying on , the fault showed up on the IID Tool as the drivers seatbelt tensioner . After checking the cable and connections the light went out and stayed out ! This happened a couple of times but managed to remedy the fault as before ! However it's now back with a vengeance , I have plugged in the IIDTool but I'll it says now is ' no communication with ecu ' ! I've checked the cables on both front seats , I have checked the fuse in the fuse box behind the glovebox , and that's ok , I've even disconnected the battery for a short while to see if that sorts it but alas no ! Any ideas ? Thanks
