B0062Knee Airbag Deployment Loop Short to Ground

How the car detects it: None of the publicly available J2012 code lists contain B0062; they jump from B0061 to B0070, and no carmaker describes it with the knee airbag meaning shown in the title. J2012 files knee airbag loops under B0004 for the driver and B0013 for the passenger, with the fault type in the added byte; Mercedes-Benz logs kneebag squib faults as B000413 and B001313, and in that scheme a grounded loop would carry byte 11 instead. The only public use of B0062 is at Saab: 9-3 airbag modules (manuals of 2003 and 2007) store it for the driver-side curtain or rollover bar loop, with byte 04 for open and 0E for resistance too high. Knee airbags sit in the lower dash; an IIHS study of 414 crash tests found little overall benefit for belted drivers.
