A. Test
   (1) Do a manual reset of the CIDS as follows:
     (a) In the avionics compartment on the C/B Panel 121VU:
  • Open the C/Bs CIDS DIR2 NORM 156RH and CIDS DIR1 NORM 151RH.
     (b) In the avionics compartment on the C/B Panel 49VU:
  • Open the C/Bs CIDS DIR2 ESS 157RH and CIDS DIR1 ESS 150RH.
     (c) Wait for a minimum of 10 seconds.
     (d) In the avionics compartment on the C/B Panel 49VU:
  • Close the C/Bs CIDS DIR2 ESS 157RH and CIDS DIR1 ESS 150RH.
     (e) Wait for a minimum of 5 minutes.
     (f) In the avionics compartment on the C/B Panel 121VU:
  • Close the C/Bs CIDS DIR2 NORM 156RH and CIDS DIR1 NORM 151RH.
NOTE: It is possible that because of the boot up in ESS mode, there are no internal defects shown.
