5.1.3. Check of frequency of rotation of idling

Before check of frequency of rotation of idling be convinced that spark plugs, fuel nozzles, the modulator of frequency of rotation of idling (ISC), a compression, etc. are in an order.

Check conditions

 PERFORMANCE ORDER

  1. Connect a tachometer to primary winding of the coil of ignition or the scanner to the diagnostic socket.
  2. Launch the engine and leave it to work at the frequency of rotation of a bent shaft idling.
  3. No more, than on 5 with increase the frequency of rotation of a bent shaft to 2000-3000min-1 then let's it work idling within 2 min.
  4. Determine idling rotation frequency by a tachometer.

Idling rotation frequency:

Engine of 1,6 l: 850±100 min.-1
L engines 1,8 and 2,0: 700±100 min. –1
