TASK 32-45-00-810-804-A
CONFIG PARK BRK ON Warning is not Shown on the Upper ECAM DU with the PARK BRK Control Switch at ON


1. Possible Causes
  • wiring from the pin B/D of the parking brake electrical control valve (72GG) to the ground terminal
  • CTL VALVE-PARK BRK,ELEC. [72GG]
  • wiring from the pin A/A of the parking brake pressure switch (86GG) to the parking brake electrical control valve (72GG) pin B/D.
  • PRESS SW-PARK BRK [86GG]
  • wiring from the parking brake electrical control valve (72GG) pin B/E to the SDAC (1WV1) pin AD/7C
  • wiring from the pin B/4 of the parking brake electrical control valve (102GG) t the ground terminal
  • CTL VALVE-PARK BRK, ELEC [102GG]
  • wiring from the parking brake electrical control valve (102GG) pin A/5 to the SDAC (1WV1; 1WV2) pin AD/7C

A. If the CONFIG PARK BRK ON warning does not come into view when the PARK BRK control switch is at ON (during flight phases 3 and 4):
  • set the PARK BRK selector switch to ON.
  • do a check for a ground signal at pin B/E of the parking brake electrical control valve (72GG) ASM 324501.
   (1) If there is no ground signal:
  • do a check for a ground signal at pin B/D of the parking brake electrical control valve (72GG) ASM 324501.
     (a) If there is no ground signal:
  • do a check and repair the wiring from the pin B/D of the parking brake electrical control valve (72GG) to the ground terminal ASM 324501.
     (b) If there is a ground signal:
   (2) If there is a ground signal:
  • do a check for a ground signal at pin A/B of the parking brake pressure switch (86GG) ASM 324501.
     (a) If there is no ground signal:
  • do a check for a ground signal at pin A/A of the parking brake pressure switch (86GG) ASM 324501.
       1 If there is no ground signal:
  • do a check and repair the wiring from the pin A/A of the parking brake pressure switch (86GG) to the parking brake electrical control valve (72GG) pin B/D. ASM 324501.
       2 If there is a ground signal:
     (b) If there is a ground signal:
  • do a check and repair the wiring from the parking brake electrical control valve (72GG) pin B/E to the SDAC (1WV1) pin AD/7C ASM 324501.
Subtask 32-45-00-810-053-C ** ON A/C NOT FOR ALL
A. If the CONFIG PARK BRK ON warning does not come into view when the PARK BRK control switch is at ON (during flight phases 3 and 4):
  • Set the PARK BRK selector switch to ON.
  • Do a check for a ground signal at pin B/5 of the parking brake electrical control valve (102GG) ASM 324501.
   (1) If there is no ground signal:
  • Do a check for a ground signal at pin B/4 of the parking brake electrical control valve (102GG) ASM 324501.
     (a) If there is no ground signal:
  • Do a check and repair the wiring from the pin B/4 of the parking brake electrical control valve (102GG) t the ground terminal ASM 324501.
     (b) If there is a ground signal:
   (2) If there is a ground signal:
  • Do a check and repair the wiring from the parking brake electrical control valve (102GG) pin A/5 to the SDAC (1WV1; 1WV2) pin AD/7C ASM 324501.
