Removing
To remove the air cleaning filter, perform the following operations.
1. Disconnect a wire from the negative plug of the storage battery.
Attention! After the power is turned off (fan switch in position «OFF» or ignition switch in position «ACC» or «LOCK»), high pressure is maintained in the air cleaning filter for about 5 seconds. Accordingly, wait about 5 seconds after turning off the power before removing the air purifying filter.
2. Remove the bottom cover.
3. Remove the glove box.
4. Remove the corner cover.
5. Remove a glove box frame.
6. Remove the side panel (passenger side).

7. Loosen the screws and remove the power transistor 4 (pic. 18.17).
8. Turn away screws and remove the filter of cleaning 7 air in gathering.
Disassembly
To disassemble the air purification filter, perform the following operations.

1. Remove the mesh filter element 1 (pic. 18.18).
2. Remove ionizer 2 from the body.
3. Remove manifold 4.
4. Remove the transformer assembly 5.
Examination
When checking the ionizer, measure the voltage in the collector and on the ionizer as follows.

1. Move the air purification filter to the opposite side and connect the connector so that the unit can work (pic. 18.19).
Attention! Do not connect a power transistor.
2. Connect high voltage probes (capable of measuring voltage up to 10,000 V) to the digital tester.
Attention! When taking measurements, be careful not to short the leads.
3. Start the engine and set the fan switch to «HI» (high).

4. Connect «negative» («–») high-voltage probe probe to negative («–») negative terminal on the collector side (pic. 18.20).
If the measured touch voltage («+») probe of the high-voltage probe to («+») output from the collector side is not lower than 2000 V, then the collector can be considered serviceable.
If the measured touch voltage («+») probe of the high-voltage probe to («+») output on the side of the ionizer is not lower than 4000 V, then the air ionizer can be considered serviceable.
