Function Test: Civic

  1. Ensure fuse No. 51 (20-amp) in underhood fuse/relay box and No. 24 (7.5-amp) in underdash fuse/relay box are not open. Replace as necessary. Carefully pry sun roof switch/cruise control switch out of instrument panel. Unplug connectors from switches. Using an ohmmeter, check for continuity between control switch connector terminal No. 4 (Black wire) and body ground. If no continuity exists, check for open in Black wire. See WIRING DIAGRAMS  . Repair as necessary.
  2. Connect jumper wire between connector terminal No. 1 (Yellow wire) and body ground. Turn ignition on. If sun roof opens, check switch. See SUN ROOF SWITCH  under COMPONENT TESTING. If sun roof does not open, check for open in Yellow wire between sun roof switch and sun roof open relay, faulty open or close relay or a poor ground. See WIRING DIAGRAMS  . Repair or replace as necessary.
  3. Connect jumper wire between connector terminal No. 3 (Yellow/Red wire) and body ground. Turn ignition switch to ON position. If sun roof closes, check switch. See SUN ROOF SWITCH  under COMPONENT TESTING. If sun roof does not close, check for open in Yellow/Red or Green/Red wire between sun roof switch and sun roof close relay. See WIRING DIAGRAMS  .

See SUN ROOF SWITCH  under COMPONENT TESTING. If sun roof does not tilt, check for open in Blue wire between sun roof switch and tilt/close switch or a faulty tilt/close switch. See WIRING DIAGRAMS  .
  5. Connect jumper wire between connector terminal No. 3 (Yellow/Red wire) and ground. Turn ignition switch to ON position. Sun roof should tilt down. If sun roof does not tilt down, the open/close relay is faulty.
