Check and adjustment of time of an advancing of ignition
|
|
Before start of the engine, transfer the transmission lever to "neutral" situation (in models from A/T in the range of "P"), and install the parking brake. |
|
|
Start the engine and warm up it up to the normal working temperature.
Make sure that all electric loading besides ignition is disconnected.
Check and be convinced that the speed of idling meets the specification.
Using the SUZUKI scanner
|
|
Connect the SUZUKI scanner to DLC (1) at the switched-off ignition, again start the engine and determine ignition advancing time, using the mode of the fixed SUZUKI scanner spark. Special tool (A): SUZUKI scanner.
|
Without using the SUZUKI scanner
|
|
Ground for check a conclusion of the switch (2) in the coupling of diagnostics (1) using an office wire to record ignition advancing time as initial.
|
Establish a stroboscope on an assembly plait of ignition for the cylinder No. 1.
Using a stroboscope, check that the advancing time observed from a point (1) meets the specification.
Point of observation of initial time of an advancing of ignition (when it is established by means of the SUZUKI Scanner or an office wire): 5 ± 1 ° BTDC

If time of an advancing of ignition does not meet the specification, release a flange bolt(s) (2), adjust advancing time, turning CMP a sensor (1) at the working engine, and then tighten a bolt(s) (2). Torque of an inhaling: bolt(s) of a sensor of CMP of 15 N • m (1.5 kg-m, 11.0 pounds feet).
After a bolt(s) inhaling check again whether ignition advancing time meets the specification.
After check and/or adjustment, leave the mode of the fixed spark of the SUZUKI scanner or disconnect an office wire from diagnostics socket.
|
|
Driving at the grounded conclusion of the switch can become the reason of damage of the catalyst. Surely disconnect an office wire after adjustment. |
|
|
In this state time of an advancing of ignition can vary in comparison with initial time of an advancing of ignition, but it is normal. |
During the operation of the engine idling (situation with the closed throttle and at a vehicle stop), check that ignition advancing time about BTDC 12 ° -16 ° (J20 engine). Also check that increase in speed of the engine accelerates ignition advancing time. If results of check are unsatisfactory above, check the entrance signals connected with system of ignition.
