Fault Type	Description		ABC Type
64h	Plausibility Failure		Sbx_cf
F1h	Safety Case 1		Sbx_cf
F2h	Safety Case 2		Sbx_cf
F3h	Multiple Failure		Sbx_cf
Detection Conditions for Bit 4 (readiness)
64h	[No accelerator pedal track 1 or 2 signal detected failure (high or low) AND no failure on acc. pedal track 1 or 2 power supply] OR DTC 0226h present
F1h	– accelerator pedal variation < 0,300097751710654 Uref ratio/s – accel pedal position > 0,204301075268817 Uref ratio – vehicle speed > 0 km/h – no accelerator pedal detected failure, – no AYC, ASR or MSR current request if configuration bit is not set, – accelerator pedal sensor information not invalid. – engine speed > 608 rpm. – no braking setpoint from Adaptive Cruise Control system (only for applications with ACC) if configuration bit is not set. – brake pedal pressed
F2h	– accelerator pedal variation < 0,300097751710654 Uref ratio/s – accel pedal position > 0,204301075268817 Uref ratio – vehicle speed > 0 km/h – no accelerator pedal detected failure, – no AYC, ASR or MSR current request if configuration bit is not set, – accelerator pedal sensor information not invalid. – engine speed > 608 rpm. – no braking setpoint from Adaptive Cruise Control system (only for applications with ACC) ifconfiguration bit is not set. – brake pedal pressed
F3h	Always
Detection Conditions for Bit 0 (test failed)		Detection timing	Resorption Timing
64h	Difference between accelerator pedal track 1 & 2 position > [6%..8%] Uref ratio	400 ms	1600 ms
F1h	No accelerator pedal position variation during at least cxx_acel_pdl_dly1 + cxx_acel_pdl_dly2 AND brake pedal pressed during cxx_acel_pdl_dly2	1200 ms	20 ms
F2h	No accelerator pedal position variation during at least cxx_acel_pdl_dly1 + cxx_acel_pdl_dly2 AND brake pedal pressed during cxx_acel_pdl_dly2	30000 ms	0 ms
F3h	[(DTC 2120h OR DTC 0641h) AND DTC 0226h] OR [(DTC 0225h OR DTC 0651h) AND DTC 0226h] OR [(DTC 2120 OR 0641h) AND (DTC 0225h OR DTC 0651h)]	250 ms	10000 ms
