Check and adjustment of time of an advancing of ignition

Before engine start, translate the transmission lever in "neutral" position (in models with A/T in a range "P"), and establish a lay brake.


 PERFORMANCE ORDER

  1. Start the engine and warm up it to normal working temperature.
  2. Be convinced that all electric loading besides ignition is disconnected.
  3. Check up and be convinced that speed of idling corresponds to the specification.

Using scanner SUZUKI

  1. Connect scanner SUZUKI to DLC (1) at the switched off ignition, again start the engine and establish time of an advancing of ignition, using a mode of the fixed spark of scanner SUZUKI. The special tool (A): scanner SUZUKI.

Without using scanner SUZUKI

  1. Earth for check a conclusion of the switch (2) in муфте diagnostics (1) using an office wire to fix time of an advancing of ignition as the initial.
  1. Establish a stroboscope on an assembly plait of ignition for the cylinder №1.
  2. Using a stroboscope, check up that time of an advancing observed from a point (1), corresponds to the specification.
    • Point of supervision over initial time of an advancing of ignition (when it is established by means of Scanner SUZUKI or an office wire): 5 1 BTDC
    • Order zazhiganija:1-3-4-2 (engine J20)
    • The special tool (A): 09930-76420

  1. If time of an advancing of ignition does not correspond to the specification, release фланцевый () a bolt () (2), adjust advancing time, turning CMP a sensor control (1) at the working engine, and then tighten a bolt () (2). An inhaling Twisting moment: a bolt () sensor control CMP 15 Н•м (1.5 kg th, 11.0 pounds-foots).
Engine J20.
  1. After a bolt inhaling (ов) again check up, whether there corresponds time of an advancing of ignition of the specification.
  2. After check and-or adjustment, leave a mode of the fixed spark of scanner SUZUKI or disconnect an office wire from diagnostics socket.

Driving at the earthed conclusion of the switch can become the reason of damage of the catalyst. Necessarily disconnect an office wire after adjustment.


In this condition time of an advancing of ignition can vary in comparison with initial time of an advancing of ignition, but it is normal.

  1. At engine work idling (position with the closed throttle and at a vehicle stop), check up that time of an advancing of ignition nearby BTDC 12 -16 (engine J20). Also check up that the increase in speed of the engine accelerates time of an advancing of ignition. If results of check are above unsatisfactory, check up the entrance signals connected with system of ignition.
