once the following parameters are met:
o
Waiting time, vehicle must be stationary
for at least 2 minutes to allow the oil to
settle;
o
Engine at idle;
o
Oil at normal operating temperature,
between 140°F (60°C) and 220°F (104°C);

NOTE
Note that the quantities LO 4 and HI 3 are the
largest values displayed and that the actual
variation in oil level may exceed these
numbers.
NOTE
Failure to meet one of the above parameters
will stop the two minute countdown. One of
the codes shown hereafter will indicate the
cause of the countdown interruption. Once all
parameters are met, the countdown will
continue from where it left off.
If the fluid level check cannot be completed, an
Invalid for Display fault is reported. This
condition is reflected by the display of "OL",
followed by “–“, followed by one or two additional
characters. The displayed characters define the
cause of the fault, which may be either a system
malfunction or an improper condition for
conducting the check.
