IGNITION TIMING

NOTE:
Before starting engine, place transmission gear shift lever in
"Neutral" (shift selector lever to "P" range for A/T model), and
set parking brake.
INSPECTION AND ADJUSTMENT
1) Connect SUZUKI scan tool (1) to DLC (2) with ignition switch
OFF.
2) Start engine and warm it up to normal operating temperature.
3) Make sure that all of electrical loads except ignition are
switched off.
4) Check to be sure that idle speed is within specification.
(Refer to SECTION 6E1)
5) Set timing light to No.1 high-tension cord.
6) Fix ignition timing to initial one as follows:
Select "MISC" made on SUZUKI scan tool and fix ignition tim-
ing to initial one.
7) Using timing light, check that timing is within specification.
Initial ignition timing (Ignition timing fixed):
5 ± 3_ BTDC (at idle speed)
Ignition order: 1-3-2
Special Tool
(A): 09900-27301 or 09930-76420
8) If ignition timing is out of specification, loosen flange bolts, ad-
just timing by turning distributor assembly while engine is run-
ning, and then tighten bolts.
Tightening Torque
.
(a): 15 N m (1.5 kg-m, 11.0 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.
11) With engine idling (ignition timing not fixed, idle switch ON and
car stopped), check that ignition timing is about 10_ BTDC.
(Constant variation within a few degrees from 10_ 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 CTP switch,
test switch terminal circuit and ECM.
