4. Fault Isolation
_______________
A. The ECAM warning message ENG 1 EGT DISCREPANCY is generated if the cockpit indicated EGT and the EGT output selected from the ECU disagree.
(1) Disconnect harnesses from the EGT sensor receptacles, HJ13 and CJ13 (upper right hand and left hand thermocouple connectors, lower left hand and right hand thermocouple connectors).
R (a) Visually examine the receptacle and the connector for damaged R pins or contamination (Ref. AMM TASK 73-21-50-210-002).
1 If damage is found:
_ - repair or replace as required.
2 If no damage is found:
_
- do a cleaning of the connector and receptacle using a bristle brush with stoddard solvent (Material No. CP2011) (Ref. AMM TASK 73-21-50-210-002).
(2) Disconnect harnesses from the ECU (4000KS), HJ3 and HJ4.
R (a) Visually examine the receptacle and the connector for damaged R pins or contamination (Ref. AMM TASK 73-21-50-210-002).
