ENGINE GENERAL INFORMATION AND DIAGNOSIS (G13/G16 ENGINE WITH WU TWC) 6-1-7
Warm-up Cycle
A warm-up cycle means sufficient vehicle operation such that the
coolant temperature has risen by at least 225C (405F) from engine
starting and reaches a minimum temperature of 705C (1605F).
Driving Cycle
A "Driving Cycle" consists of engine startup, driving mode where
a malfunction would be detected if present, and engine shutoff.
2 Driving Cycles Detection Logic
The malfunction detected in the first driving cycle is stored in ECM
(PCM) memory (in the form of pending DTC and freeze frame data)
but the malfunction indicator lamp does not light at this time. It lights
up at the second detection of same malfunction also in the next
driving cycle.
Pending DTC
Pending DTC means a DTC detected and stored temporarily at 1
driving cycle of the DTC which is detected in the 2 driving cycle
detection logic.
Freeze Frame Data
ECM (PCM) stores the engine and driving conditions (in the form
of data as shown at the left) at the moment of the detection of a mal-
function in its memory. This data is called "Freeze frame data".
Therefore, it is possible to know engine and driving conditions
(e.g., whether the engine was warm or not, where the vehicle was
running or stopped, where air/fuel mixture was lean or rich) when
a malfunction was detected by checking the freeze frame data.
Also, ECM (PCM) has a function to store each freeze frame data
for three different malfunctions in the order as the malfunction is
detected. Utilizing this function, it is possible to know the order of
malfunctions that have been detected. Its use is helpful when re-
checking or diagnosing a trouble.
Priority of freeze frame data:
ECM (PCM) has 4 frames where the freeze frame data can be
stored. The first frame stores the freeze frame data of the malfunc-
tion which was detected first. However, the freeze frame data
stored in this frame is updated according to the priority described
below. (If malfunction as described in the upper square "1" below
is detected while the freeze frame data in the lower square "2" has
been stored, the freeze frame data "2" will be updated by the freeze
frame data "1".)

FREEZE FRAME DATA IN FRAME 1
Freeze frame data at initial detection of malfunction
among misfire detected (P0300-P0304), fuel system
too lean (P0171) and fuel system too rich (P0172)
Freeze frame data when a malfunction other than
those in "1" above is detected
