Swift GL L4-1298cc 1.3L SOHC MFI (2000)
6. Detach air cleaner case (housing) and shift air cleaner case and hose position to observe ignition timing.
7. Using timing light, 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
Special Tool
(A): 09900-27301 or 09930-76420
8. If ignition timing is out of specification, check the followings:
-
CKP sensor
-
Crankshaft timing belt pulley (signal rotor)
-
TP sensor
-
Test switch signal circuit
-
VSS
-
Timing belt cover installation
9. After checking Initial Ignition Timing, release ignition timing fixation by using SUZUKI scan tool or disconnect service wire from monitor
connector.
10. With engine idling (test switch terminal ungrounded, throttle opening at closed position and car stopped), check that ignition timing is about 12 ° -
15 ° BTDC. (Constant variation within a few degrees from 12 ° - 15 ° 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 sensor, test
switch terminal circuit and ECM (PCM).
11. Install air cleaner case.
