R - do a check of the aircraft wiring between the oil temperature
R sensor (4004EN) and the EIU (1KS1) for open or short to ground
R (Ref. ASM 79-36/01) pin AA/1 to pin AA/10F. Pay particular
R attention to engine to pylon connectors 4005VC-A, 405VC-A, 4006VC-A
R and 406VC-A and to ground wire connections (9951DC, 9956DC and
R 9957DC) on Engine Fan Case (check for looseness or contamination).
R (a) if damage is found:
R - repair or replace the harness as necessary (Ref. AMM TASK 71-R 51-43-000-001) and (Ref. AMM TASK 71-51-43-400-001).
R (b) if nothing is found:
R - replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040) and
R (Ref. AMM TASK 73-25-34-400-040).

R
R (1) Check that failure message ECU1 4000KS OR OIL TEMP SENSOR 1 4004EN is
R no longer present.

Removal of the Left Side Harness (4216KS)
Installation of the Left Side Harness (4216KS)
Removal of the Engine Interface Unit (EIU)
(1KS1,1KS2)
Installation of the Engine Interface Unit (EIU)

R NOTE : The fault is triggered if the oil temperature sensor (4004EN)____
R indicates a temperature greater than 140 deg. C while the ECU
R temperature sensor indicates a temperature in between - 55 deg. C
R and 135 deg. C. This is indicative of a faulty output of oil
R temperature sensor (4004EN).
