Ignition Timing InspectionS7RS0B1806007
NOTE
• Ignition timing is not adjustable. If ignition
timing is out of specification, check
system related parts.
• 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) Connect scan tool to DLC (1) with ignition switch OFF.
Special tool
(A): SUZUKI scan tool
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 referring to “Idle Speed and IAC
Throttle Valve Opening Inspection in Section 1A”

of specification, check the
followings.
• CKP sensor
• CKP sensor plate
• CMP sensor
• CMP sensor rotor tooth of camshaft
• VSS
• Timing chain cover installation
8) After checking initial igniti on timing, release ignition
timing fixation by using scan tool.
9) With engine idling (throttl e opening at closed position
and vehicle stopped), check that ignition timing is
about 3 ° – 13° BTDC. (Constant variation within a
few degrees from 3 ° – 13° BTDC indicates no
abnormality but proves operation of electronic timing
control system.) Also, check that increasing engine
speed advances ignition timing.
If the check results are not satisfactory, check CKP
sensor and ECM.
