Checking the dust sensor (P.C.B D unit)
■What to check/Method
<Check 1> Checking the Front body assy dust sensor
• Check that there lint, hair, dust or foreign objects clinging to the sensor.
<Check 2> Checking the insertion, connection and conduction conditions of the connector housing
• Make a visual check of whether the Lead wire A assy connector housing is properly inserted and connected.
• Check that there is no burnout or poor connection, etc. of lead wires AU by performing a conduction check using a tester.
<Check 3> Checking the condition of soldering on soldered lead wires/connector housing
• Make a visual check of soldered lead wires/connector housing for poor soldering, broken trances, etc.
• Check that there is no burnout or poor connection, etc. of lead wires by performing a conduction check using a tester.
<Check 4> Visual check of the P.C.B for any cracking, damaged electrical components, poor soldering, bro-
ken trances, etc.
■Action
• Securely connect connector housings.
• Replacing the P.C.B D unit
