Automatic Transmission/Transaxle: 5A-9
On-Board Diagnostic System Description
S3RH0A5101006
For Vehicle with Immobilizer Lamp
For automatic transaxle control system, TCM has the
following functions.
• When TCM detects a malfunction in A/T control
system, it stores malfunction DTC and at the same
time transmits DTC of that malfunction to ECM. Based
on this signal, ECM turns ON malfunction indicator
lamp (MIL) (2) and stores DTC / freeze frame data in
its memory.
• If no malfunction is detected after detecting
malfunction, TCM immediately halts to transmit DTC
of that malfunction to ECM, however, DTC stored in
TCM memory will remain. If ECM receives no DTC of
malfunction for 3 driving cycles continuously, it turns
MIL off although DTC stored in ECM memory will also
remain.
• It is possible to communicate with ECM and/or TCM
through data link connector (DLC) (3) by using
SUZUKI scan tool (4). 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 (6). DTC is displayed on odometer by
connecting diagnosis switch terminal (8) with ground
terminal (9) of monitor connector (color in Blue) (7),
with reset button (5) 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 again.
