5A-10 Automatic Transmission/Transaxle:
2 Driving Cycle Detection Logic
When a malfunction is detected during initial driving
cycle, TCM transmits a data to inform ECM of
malfunction occurrence. At this time, ECM stores a
corresponding pending DTC in its memory. (but MIL
does not light). If the same malfunction is also detected
in next driving cycle, ECM lights MIL when it receives a
data informing occurrence of a malfunction from TCM.
Freeze Frame Data
Refer to "Freeze frame data" in "On-Board Diagnostic
System Description in Section 1A".
For Vehicle without Immobilizer Lamp
For automatic transaxle control system, TCM has
following functions.
• 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. If O/D off switch is ON at
this time, however, "O/D OFF" lamp remains ON to let
driver known that gear is not shifted to overdrive gear.
• When TCM detects a malfunction in A/T control
system, it flashes "O/D OFF" lamp (1) and stores
malfunction DTC in its memory.
• It is possible to communicate with TCM through data
link connector (DLC) (2) by using SUZUKI scan tool
(3). Diagnostic information can be checked and
erased by using scan tool.
• It is also possible to check DTC stored in TCM
memory by displaying DTC on digital display
odometer (5). DTC is displayed on odometer by
connecting diagnosis switch terminal (7) with ground
terminal (8) of blue monitor connector (6) while reset
button (4) is pressed. If no malfunction DTC is stored
in TCM memory, DTC No.12 is displayed. If one or
more DTCs are stored in TCM memory, they are
displayed 3 seconds each sequentially. After all DTCs
are displayed, they are displayed in the same manner
as above repeatedly.
