1) "Continuous" under the "Time Required" column indicates that the specified test cycles at a frequency greater than once every 0.5 seconds whenever the
test entry conditions are met.
2) "Once per driving cycle" under the "Time Required" column indicates that the specified test will complete during the first 2 bags of an FTP as well as under
the test entr
y conditions specified, on the road.
3)All test entry condition parameters are measured instantaneously unless otherwise indicated.
p) If a 6 hour soak is met, some strategies will not require another continuous 6 hour soak if the customer performs a brief key-off. This has been put into
effect to improve evap monitor completion frequency.
q) Some strategies will have the ability to base evap monitor soak length on the CARB cold soak criteria which consists of an ECT range and ACT/ECT
differential.
r) A minimum soak time has been added to CARB's cold soak criteria (footnote q) to allow calibrators to set a minimum soak time if longer soak times are
n
eeded than given by the ACT/ECT-based CARB soak criteria.
a) A pending code will be stored after a malfunction has been detected on one driving cycle; a DTC will be stored after the same malfunction has been detected on the second consecutive driving cycle. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been
extinguished for the DTC.b) A DTC will be stored immediately upon detection of a malfunction. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for the DTC.k) A DTC will be stored after a malfunction has been detected on one drive cycle.The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for that DTC.l) A DTC will be stored after a malfunction has been detected on six consecutive drive cycles. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for that DTC.o)For intake air temperatures below 20 deg F, no DTC will set for indicated AIR malfunction.
s) A DTC will be stored after an evaporative system leak has been detected and the refueling debounce check has been completed on the subsequent
driving cycle
c)The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles.
The MIL will be extinguished after three consecutive driving cycles where the monitor was run without a malfunction.d)The MIL will blink immediately upon detection of a misfire rate that exceeds the catalyst damage threshold, regardless of whether fuel is shut off or not.
If the misfire rate drops below the catalyst damage threshold, the MIL will stay on solidly.
The MIL will be extinguished after three consecutive drive cycles where similar conditions have been seen without the malfunction.e)The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles.
The MIL will be extinguished after three consecutive drive cycles where similar conditions have been seen without the malfunction.f)For intake air temperatures below 32 deg F, the MIL will not illuminate for the indicated EGR DTCs.
For barometric pressures below 22.5"Hg, the MIL will not illuminate for the indicated EGR DTCs.
For intake air temperatures below 20 deg F, the MIL will not illuminate for the indicated AIR DTCs.
This prevents false MIL illumination due to ice in the EGR hoses or AIR switching valve(s).g)This monitor employs EWMA.
The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles after DTCs have been erased or Keep Alive Memory
h
as been erased (battery disconnect).
The MIL will be illuminated after a malfunction has been detected on up to six consecutive driving cycles during subsequent, "normal" customer driving.
The MIL will be extinguished after up to six consecutive driving cycles without a malfunction.
h) Some automatic transmission monitors are demonstrated following the USCAR Abbreviated On-Board Diagnostic Test Procedure for Vehicles Equipped
wi
th Automatic Transmissions.
This prevents false MIL illumination on this non-turbine speed sensor transmission application.
i)The MIL will be illuminated after a malfunction has been detected on the first driving cycle.
The MIL will be extinguished after three consecutive driving cycles where the monitor was run without a malfunction.j)A DTC will be set after a malfunction has been detected on two consecutive driving cycles.
m) MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles. MIL will be extinguished after the monitor has run
wi
thout a malfunction (same or subsequent drive cycle).
n) A check cap light will be illuminated after a malfunction has been detected on one driving cycle. The check cap light will be extinguished after the monitor
h
as run without a malfunction (same or subsequent drive cycle).
