_______________
 A. If the test gives the maintenance message CHECK LGCIU 2 L/G COMP SIGNALS (DISAGREE):
 - replace the EIU-2 (1KS2) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
 (1) If the fault continues:

 - replace the LGCIU-2 (5GA2) (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).

 (2) If the fault continues:

 - do a check and repair the wiring from the pins AA/5D, 5E of the EIU-2 (1KS2) to the pins AB/3G, 3K of the LGCIU 2 (5GA2) (Ref. ASM 73-25/16).

 B. Test
 (1) During the subsequent engine start make sure that:

 - no ECAM warning or/and amber crosses do not come into view on the ECAM

 - the engine idle must not be high

 (2) After a subsequent flight make sure that the maintenance message is no more present.

 4. Fault Isolation
_______________
 A. If the fault is also present on engine 2:
 - replace the CONT-ZONE TEMPERATURE (8HK) (Ref. AMM TASK 21-63-34-000-001) and (Ref. AMM TASK 21-63-34-400-001).
 (1) If the fault is present on engine 1 only:
 - do a check of the wiring between the EIU1 (1KS1) pins AA/2J, AA/2K and terminal block 1853VT and between the EIU1 (1KS1) pins AA/3J, AA/3K and terminal block 1853VT (Ref. AWM 73-25-19).
 (a) If the wiring is not correct:

 - Repair as required.

 (b) If the wiring is correct:

 - replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
