PERFORMANCE ORDER
1. Remove the 6-shtyrkovy plug from the relay of management of a warming up, turn the ignition key in situation "2" and connect a control wire of a counter 1 and 3 on the plug.
2. If now the control bulb of a warming up shines, then the relay of management of a warming up is faulty, replace the relay. Otherwise take the glow lamp, check it and if necessary replace.
3. If the lamp is serviceable, then check an ohmmeter passing of current on a black wire between a counter 3 and the glow lamp, if necessary check contact of a lamp with the case, eliminate break of a wire.
Prevention

If the long time shines a lamp of a preliminary warming up, it indicates malfunction of the relay of management of a warming up (contacts stuck together).
