11.6.4.1. Possible malfunctions of microprocessor system of ignition

REASON
ELIMINATION METHOD
The engine is not started
Contact connections in power-supply circuits of the controller or coils of ignition (a wire of red color) are broken.
To check and restore contact connections of sockets of a plait of wires, and also fastening of "mass" wires.
Signals from inductive sensors on the controller do not arrive:
  – sensors on a coupling case are unreliably fixed;
  – to check and fix sensors;
  – sensors are faulty   – to check, to replace faulty sensors
Contact connections in the operating chain of one of ignition coils (a wire of blue or white-black color) are broken. To check and restore contact connections
The ignition coil is faulty.
To check and if necessary to replace.
The controller is faulty.
To replace the controller.
The engine works with interruptions
High-voltage wires and caps to spark plugs are damaged (breakdown on "weight")
To check, to replace the damaged wires and caps
Spark plugs are damaged (cracks on the insulator, wear of electrodes, a deposit etc.)
To check, clear, adjust a gap between electrodes; to replace the damaged candles
Contact connections of sockets of wires to inductive sensors and fastening of sensors to a coupling case are unreliable
To check and restore connections, and also fastening of sensors
The engine does not develop full capacity
The engine does not develop full capacity
To check, remove fuel condensate; to replace the damaged tube
Closes on "weight" a wire to the sensor screw
To check, remove fuel condensate; to replace the damaged tube
Temperature sensor is faulty
To check, to replace the faulty sensor
The controller is faulty
To replace the controller
