5) Fix ignition timing to initial one as follows.
a) When using SUZUKI scan tool:
Select “MISC” mode on SUZUKI scan tool and fix ignition
timing to initial one.
b) Without using SUZUKI scan tool: (vehicle without immobi-
lizer indicator lamp)
Disconnect scan tool from DLC, and connect D and E ter-
minals of monitor connector (1) or E to body ground by
using service wire so that ignition timing is fixed on initial
one.
6) Using timing light (1), check that ignition timing is within
specification.
Initial ignition timing (test switch terminal grounded or
fixed with SUZUKI scan tool)
5
± 3° BTDC at idle speed
Ignition order
1-3-4-2
7) If ignition timing is out of specification, check the followings:
CKP sensor
CKP sensor plate
TP sensor
Test switch signal circuit
VSS
Timing chain cover installation
8) After checking Initial Ignition Timing, release ignition timing
fixation by using SUZUKI scan tool or disconnect service
wire from monitor connector.
9) With engine idling (test switch terminal ungrounded, throttle
opening at closed position and car stopped), check that igni-
tion timing is about 7°–17° BTDC. (Constant variation within
a few degrees from 7°–17° indicates no abnormality but
proves operation of electronic timing control system.) Also,
check that increasing engine speed advances ignition timing.
If above check results are not satisfactory, check CKP sen-
sor, test switch terminal circuit and ECM.
