Ignition Timing: Testing and Inspection

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.

1. Start engine and warm it up to normal operating temperature.
2. Make sure that all of electrical loads except ignition are switched OFF.




3. Check to be sure that idle speed is within specification.
4. Connect SUZUKI scan tool to DLC with ignition switch OFF, restart engine and fix ignition timing by using fixed spark mode of SUZUKI scan tool.

Special Tool
(A): 09931 - 76011 (SUZUKI scan tool)
(B): Mass storage cartridge
(C): 16/14 pin DLC (OBD-II adapter) cable




5. Set timing light to high-tension cord for No.1 cylinder.
6. Using timing light, check that timing is within specification.

Initial ignition timing of viewpoint
(when it is fixed by SUZUKI scan tool): 5 ± 1 ° BTDC
Ignition order: 1-3-4-2

Special Tool
(A): 09930 - 76420

7. If ignition timing is out of specification, check the followings:
- CMP sensor
- Signal rotor on camshaft
- TP sensor
- VSS
- Crankshaft pulley/timing belt cover installation

8. After checking, end fixed spark mode of SUZUKI scan tool.

NOTE: In this state, ignition timing may vary more or less of initial ignition timing but it is nothing abnormal.

9. With engine idling (closed throttle position and vehicle stopped), check that ignition timing is about BTDC 6 ° - 10 °. Also, check that increasing engine speed advances ignition timing. If above check results are not satisfactory, check input signals related to ignition system.
