Failure of the ECAM Control Panel
1. Possible Causes
_______________
- CTL PNL-ECAM (6WT)
- wiring from the circuit breaker (15WT) to the ECAM control panel (6WT)
- C/B-EIS/ECAM/CTL/PNL (15WT)

__________________
A. Test Do the operational test of the central warning systems (FWC) (Ref. AMM TASK 31-50-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message ECP:
- do a check of the status of the circuit breaker (15WT)
(1) If the circuit breaker (15WT) is closed:
- replace the CTL PNL-ECAM (6WT), (Ref. AMM TASK 31-61-12-000-001) and (Ref. AMM TASK 31-61-12-400-001).
(a) If the fault continues:
- do a check of the wiring from the circuit breaker (15WT) to the ECAM control panel (6WT) pin B/S and A/S , (Ref. ASM 31-61/02).
1 If there is no continuity:
_
- repair the wiring.
2 If there is continuity:
_
- replace the C/B-EIS/ECAM/CTL/PNL (15WT) (2) If the circuit breaker (15WT) is open:
- close the circuit breaker.
(a) If the circuit breaker trips:
- replace the CTL PNL-ECAM (6WT).
(b) If the circuit breaker stays closed and the fault continues:
1_ If the fault continues:
- do a check and repair for a short to ground the wiring
between the circuit breaker (15WT) and the ECAM control
panel (6WT).
- replace the CTL PNL-ECAM (6WT).
B. Do the test given in Para. 3.

B. Test Do the operational test of the central warning systems (FWC) (Ref. AMM TASK 31-50-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message ECP : NO DATA FROM DMC1 or 3:
- replace the CTL PNL-ECAM (6WT) (Ref. AMM TASK 31-61-12-000-001) and (Ref. AMM TASK 31-61-12-400-001).
(1) If the fault continues:
- do a check and repair the wiring from ECAM control panel (6WT) pins B/G,H to the first terminal block (Ref. ASM 31-61/03).
B. Do the test given in Para. 3.B.
