Check of time of an advancing of ignition

Before engine start, translate the transmission lever in "neutral" situation (in models with A/to "P" range), and establish the parking 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 and be convinced that speed of idling corresponds to the specification.
  4. Establish time of an advancing of ignition as follows [using the SUZUKI scanner].
  1. Connect the SUZUKI scanner 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 the SUZUKI scanner. Special tool (A): SUZUKI scanner.
  1. [Without using the SUZUKI scanner] (for a vehicle with the socket for the monitor): earth for check a switch (2) conclusion in diagnostics socket (white) (1) using an office wire to fix time of an advancing of ignition as the initial.
A — besides model with folding top
B — model with folding top
  1. Establish a stroboscope on a wire of a high voltage for the cylinder No. 1.
  2. Using a stroboscope, check and be convinced that time of an advancing corresponds to the specification. A sight point - initial time of an advancing of ignition (check at the earthed conclusion of the switch): 5 ± 1 ° BTDC. Ignition order: 1-3-4-2. Special tool (A): 09930-76420.
1 — a mark "V" in a crankshaft pulley
2 — 5 ° BTDC
  1. If ignition time of an advancing does not correspond to the specification, inspect as follows. For a vehicle equipped with the resistor of an advancing of ignition (2).
1 — the reducer
2 — the resistor of an advancing of ignition
    • If result of check unsatisfactory, replace the ignition resistor with consecutive number (3) on original to check, there corresponds initial time of an advancing of ignition of the specification.
  1. Choose and check the resistor with the following consecutive number, specified time of an advancing of ignition will not be received yet. For example, if the served vehicle has the ignition resistor with number "5", initial time of an advancing of ignition can be changed, having replaced it on "4" or "N".

If the resistor ignition was replaced, surely replace a label of ignition which is put on a cover of a belt of a drive of the distributive mechanism (4) on having the same symbol, as on the resistor of ignition (5).

  1. For the vehicle which has not been equipped with the resistor of an advancing of ignition. Check the following:
      • CMP sensor and CKP sensor (if is)
      • Alarm rotor on a cam-shaft
      • TP sensor
      • VSS
      • Installation of a pulley of a crankshaft/cover of a belt of a drive distributive mechanism
  2. After check, leave a mode of the fixed giving of a spark of the SUZUKI Scanner or remove an office wire from diagnostics socket.

Driving at the earthed conclusion of the switch can become the reason of damage of the catalyst. Surely 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 operation of the engine idling (situation with the closed throttle and at a vehicle stop), check that time of an advancing of ignition about BTDC 6 ° - 10 °. Also check that the increase in speed of the engine accelerates time of an advancing of ignition. If results of check are unsatisfactory above, check the entrance signals connected with system of ignition.
