7) Using timing light (1), check that timing is within specification.
Initial ignition timing (Test switch terminal grounded or
fixed by scan tool):
5
1
BTDC (at idle speed)
Ignition order 1-3-2
F8B engine
F8D engine
8) If ignition timing is out of specification, remove air cleaner as-
sembly then loosen flange bolts (1), adjust timing by turning
distributor assembly (2) while engine is running, and then
tighten bolts (1).
Tightening Torque
(a): 23 N·m (2.3 kg-m, 14.0 lb-ft)
9) After tightening distributor flange bolts, recheck that ignition
timing is within specification.
10) After checking and/or adjusting initial ignition timing, release
ignition timing fixation by SUZUKI scan tool or disconnect ser-
vice wire from monitor coupler.
11) With engine idling (test switch terminal ungrounded, vehicle
stopped), check that ignition timing is about 8
BTDC
(Constant variation within a few degrees from 8
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 test switch
terminal circuit and ECM.
