Passenger's Control Unit Input Test

Remove right kick panel. Remove passenger's multiplex control unit and disconnect electrical connector(s). Inspect connector terminals for damage or corrosion. Repair or replace as necessary and retest system. If connections are okay, using a DVOM, perform passenger's control unit input test at passenger's underdash fuse/relay block socket(s). See Fig 1 or Fig 2 . On Accord, if all input tests are okay, go to DOOR CONTROL UNIT INPUT TEST  . On Prelude, if all input tests are okay, replace passenger's multiplex control unit.
