Wiper/Washers

Control Unit Input Test (cont'd)

22-173

With the connectors still disconnected, make these input tests at the connector.

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the multiplex control unit must be faulty; replace the under-dash fuse/relay box assembly.
