On-board Diagnostic System
For automatic transaxle control system, TCM has following func-
tions.
• When ignition switch is turned ON with O/D off switch turned
OFF and no malfunction in A/T control system is detected,
"O/D OFF" lamp (1) lights for about 2 seconds after ignition
switch is turned ON and then goes OFF for bulb check.
• When TCM detects a malfunction in A/T control system,
TCM desire turning on malfunction indicator lamp (MIL) (1)
to ECM and stores malfunction DTC in TCM memory.
• It is possible to communicate with TCM through data link
1
connector (DLC) (2) by using scan tool (3). (Diagnostic infor-
mation can be checked and erased by using scan tool.)
Warm-up Cycle
A warm-up cycle means sufficient vehicle operation such that the
coolant temperature has risen by at least 22°C (40°F) from
engine starting and reaches a minimum temperature of 70°C
(160°F).
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 TCM
memory (in the form of pending DTC and freeze frame data) but
the malfunction indicator lamp (MIL) 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.
