- APU Toil can be given through the ECAM by the aircraft AIDS system, code "OTA".
- After the APU oil temperature has increased to over 38 C, do a check if both DP switches are open.
(3) If no problems were found with the above procedure, test the APU wiring harness as follows.
- Install connector P5 and P9.
- Remove connector P1 at the APU compartment bulkhead.
- Test the continuity across pins 4+9 at the firewall, no continuity is permitted.
- Test the continuity across pin 9 and structural ground, no continuit is permitted.
- Bend the wires near the plugs to test for intermittent short-circuits.
(4) If no problems were found with the above procedure, test the aircraft wiring harness as follows.
- Install connector P1 at the APU compartment bulkhead.
- Remove the ECB.
- Test continuity from pin C11 to structural ground, no continuity is permitted.
- Bend the wires near the plugs to test for intermittent short-circuits.
(5) If no problems were found per the above procedure, replace both DP switches (Ref. AMM TASK 49-91-14-000-002) and (Ref. AMM TASK 49-91-14-400-002)

__________________
A. Do the self-test of the ECB (59KD) (Ref. AMM TASK 49-00-00-710-005).
4. Fault Isolation
_______________
A. If the APU Class 3 Faults Page gives the maintenance message:
DE-OILING SOL (8083KM):
Fault Code Number: 016 or 084
- replace the DE-OILING SOLENOID VALVE (8083KM) (Ref. AMM TASK 49-91-49-000-002) and (Ref. AMM TASK 49-91-49-400-002).
(1) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/C6, J4 to the DE-OILING SOLENOID VALVE (8083KM) P15/1, 2 (Ref. ASM 49-61/02).
(a) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002).
