•Reconnect connectors and hoses securely.
After reconnecting, confirm that each function operates normally.
•Be careful that wire harnesses of airbag system pass near electrical parts and switches.
•Wire harnesses and connectors of all airbag system are yellow color. Do not use a tester on these circuits.
•Care must be taken when installing 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 filmeasily forms
on the glass, causing the wiper to chatter and judder. Therefore, be careful not to let this happen.
