Rear Wiper Intermittent Relay Inspection

Reference: REAR WIPER INTERMITTENT RELAY REMOVAL AND INSTALLATION 

1. Check INT circuit as follows.
   1. Connect battery positive (+) terminal to "h" terminal and battery negative (-) terminal to "e" terminal.
   2. Check that voltage between "b" terminal and "e" terminal changes from 0 V to battery voltage when connecting battery positive (+) terminal to "g" terminal.

      If check result is not satisfied, replace relay.

   3. Connect battery positive (+) terminal to "c" terminal.
   4. Check that voltage between "b" and "e" terminals changes as in below figure when disconnecting battery positive (+) terminal from "c" terminal.

      If check result is not satisfied, replace relay.
