I'm wondering if another diagnostic tool would reset it. I have checked the fuses, disconnected the battery while the emergency light switch was depressed, checked for pin 19 (it seems to be in place) and still the E10 code persists. I've tried every trick recommended in the lousy manual to get the B800 to communicate using both diagnostic connectors, but it just won't communicate. I bought a B800 to diagnose and reset the light, but I am only getting an E10 code. The ignition was turned on after the seat was disconnected thereby causing the airbag dash light to illuminate. I was unaware that it was important to disconnect the battery - my mistake. I recently removed the passenger seat to replace the worn bushings on the threadscrews and to replace the broken seat belt guide.
