8G-8 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
DIAGNOSIS
ECM/PCM and Immobilizer Control Module have on-board diag-
nostic system (a system self-diagnosis function) as described pre-
viously.
Investigate where the trouble is by referring to "DIAGNOSTIC
FLOW TABLE" and "DIAGNOSTIC TROUBLE CODE TABLE" on
later pages.
PRECAUTIONS IN DIAGNOSING TROUBLES
[PRECAUTIONS IN IDENTIFYING DIAGNOSTIC
TROUBLE CODE]
ECM/PCM
<Vehicle not equipped with immobilizer indicator lamp>
D Before identifying diagnostic trouble code indicated by malfunc-
tion indicator lamp or Suzuki scan tool, don't disconnect cou-
plers from ECM/PCM, battery cable from battery, ECM/PCM
ground wire harness from engine.
Such disconnection will clear trouble codes for engine and emis-
sion control system stored in memory of ECM/PCM.
D If abnormality or malfunction lies in two or more areas, malfunc-
tion indicator lamp indicates applicable codes three times each.
And flashing of these codes is repeated as long as diagnosis ter-
minal is grounded and ignition switch is held at ON position.
D When ECM/PCM detects a trouble in both engine and emission
control system and immobilizer control system, malfunction indi-
cator lamp indicates trouble codes of both systems alternately
while the ignition switch is turned ON and the diagnosis terminal
is grounded.
D Take a note of diagnostic trouble code indicated first.
