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
