Check of serviceability of functioning, removal and installation of the electromotor of a drive of screen wipers

Check of a chain of the electromotor

 PERFORMANCE ORDER

 Before starting performance of check study the corresponding electric circuits. Remember that feeding wires are usually thicker and grounding wires are painted more brightly, than. Tension stock-taking on plugs of the socket is made by approbation their shchupy the earthed lamp sampler (on 12 In). Inclusion of a lamp confirms tension existence on the plug. If during performance described below checks to reveal a cause of defect it is not possible, the car should be driven away on car repair shop for more complete diagnostics of system.

1. If screen wipers work too slowly, first of all check level of a charge of the battery (see. Head of Control and routine maintenance). At the serviceable battery remove the driving electromotor (see below) and try to move brushes manually, checking freedom of their moving. In case of need make the corresponding repair of drafts and grease axial knots. Establish the electromotor into place, include ignition and again start brushes. If speed of work of screen wipers after the brought corrections did not settle into shape, check quality of contact connections of a chain and reliability of fixing of sockets, special attention having given to a grounding condition. At a serviceable chain replace the electromotor.

2. At refusal of activation of screen wipers check a condition of the corresponding safety lock. If a safety lock as it should be, establish a wire crossing point between the plug of grounding of the driving electromotor and mass of the chassis. Repeat check. If now screen wipers start to function normally, restore reliability of contact knots of grounding. If the motor still does not work, include screen wipers on the maximum high-speed mode check serviceability of giving of a food on the motor by sounding by the voltmeter of the back party of the contact socket. Remark: It is necessary to remove the fairing panel (see. Head Body). If a food moves regularly, remove the motor and check it by direct connection to the battery. If at connection to the battery the motor works regularly, eliminate the reason of jamming of drafts of a drive of screen wipers, otherwise replace electromotor assembly. If giving on the food motor is broken, check tension existence on the relay of management of screen wipers. If on the relay a food moves regularly, serviceability of functioning of the switch by means of an ohmmeter (see. Section Check of serviceability of functioning and replacement of podrulevy switches).

3. At violation of serviceability of functioning of screen wipers in an interval mode check a chain condition on a site between the switch and the management module. If conducting as it should be measure resistance on the handle of management by a delay of the combined podrulevy switch (see. Section Check of serviceability of functioning and replacement of podrulevy switches).
4. If brushes stop in that situation which they occupy at transfer of the switch to the situation OFF, check serviceability of grounding of the electromotor (the socket from a plait). Connect an ohmmeter between any of plugs of a black wire and reliably earthed point of the chassis, - resistance should make no more than 5 Ohm.
5. If the stop of brushes occurs only after ignition switching off, disconnect electroconducting from the switch of management of functioning of screen wipers. If now brushes stop, replace the switch. If brushes continue to function, therefore, the terminal switch of the electromotor is damaged, - replace the motor.
6. If brushes at a stop do not leave under the cowl plane, check driving draft on existence of extraneous subjects under it. If nothing disturbs leaving of brushes in parking situation, check electroconducting on a chain site between the switch and the motor. In the absence of breaks replace the motor.

Electromotor replacement

 PERFORMANCE ORDER

1. Remove levers (leads) of cleaners of a windscreen.

2. Remove the panel of a forward fairing (see. Head Body).
3. Disconnect from the motor electroconducting.

4. Separate motor assembly with driving draft from a fairing.

5. Turn out fixing bolts and remove the electromotor.

6. Installation is made upside-down.
