Fault Type	Description		ABC Type
92h	Component Performance Outside its Expected Range
13h	Circuit Open		Sbx_cf
11h	Circuit Short to Ground		Sbx_cf
12h	Circuit Short to Battery		Sbx_cf
Detection Conditions for Bit 4 (readiness)
92h	Coolant temperature > -7 °C
13h	10V < battery voltage < 16V AND [[engine autonomous AND O2 sensor heater output is ON] OR at key-on]
11h	10V < battery voltage < 16V AND [[when engine autonomous AND O2 sensor heater output becomes ON] OR at key-on]
12h	10V < battery voltage < 16V AND [[engine autonomous AND O2 sensor heater output is ON] OR at key-on]
Detection Conditions for Bit 0 (test failed)		Detection timing	Resorption Timing
92h	Number of acquisition windows where the mean value of heater current is faulty = 45 wu	2 ms	2 ms
