7B1-8 AUTOMATIC TRANSMISSION (4 A/T)
On-Board Diagnostic System (Vehicle with
monitor connector)
For automatic transmission control system, PCM (ECM) has fol-
lowing functions. Refer to Section 6/6-1 for details.
•When the ignition switch is turned ON with the engine at a
stop, malfunction indicator lamp (MIL) turns ON to check the
bulb of the MIL.
•When PCM detects a trouble in electronic shift control sys-
tem, it stores its trouble code in ECM back-up memory. (The
memory is kept as it is even if the trouble was only tempo-
rary and disappeared immediately. And it is not erased
unless the power to PCM is shut off for 30 seconds or
longer.)
•It is possible to communicate through DLC by using not only
SUZUKI scan tool (2) but also generic scan tool. (Diagnostic
information can be accessed by using a scan tool.)
•ECM also indicates trouble area in memory by means of
flashing of malfunction indicator lamp (1) at the time of
inspection. (i.e. when diagnosis switch terminal (3) is con-
nected to ground terminal (4) with a service wire (5) and igni-
tion switch is turned ON.)
