WIPER AND WASHER SYSTEMS

General Description

C: CAUTION

• Connect the connectors and hoses securely dur-
ing reassembly.
• After reassembly, make sure functional parts op-
erate smoothly.
• Be careful that wire harnesses of airbag system
pass near electrical parts and switches.
• Wiring harnesses and connectors of all airbag
system are yellow color. Do not use a tester equip-
ment on these circuits.
• Care must be taken when connecting the piping
hose so that no bending, jamming, etc. are caused.
• If even a little oil or grease such as silicon oil gets
in the tank and washer passages, an oil film is eas-
ily formed on the glass, causing the wiper to chatter
and judder, therefore, be careful not to let this hap-
pen.
