Wiper and Washer Systems: Service Precautions
2012 Subaru Impreza WRX STI F4-2.5L DOHC TurboSECTION Service Precautions
General Description
CAUTION
- Connect the connectors and hoses securely during reassembly.
- After reassembly, make sure that the functional parts operate normally.
- Be careful with the airbag system wiring harness which passes near electrical parts and switches.
- Yellow connectors and harnesses with yellow tapes around them are the connectors and harnesses for the airbag system. Using a tester above such circuits may cause malfunction of airbag system. Follow the cautions for the airbag system in this case.
- Care must be taken when connecting the hose to the pipe so that no bending, jamming, etc. are caused.
- If even a small amount of silicon oil or grease enters tank and washer fluid passages, an oil film will be formed on the glass and will cause the wiper to chatter and judder. Make sure that no oil comes into contact with the system.
