(2) Make sure that the ODMS chips COUNT has not been reset. If the ODMS chips COUNT has been reset, apply (Ref. AMM TASK 79-00-00-281-805).
(3) Do an inspection of the ODMS Sensor (Ref. AMM TASK 79-36-00-220-801).
(a) If there is no oil-chip ECAM alert:
1_ Do not apply the figure (Flow Chart Decision vs Magnetic Particle) of the task (Ref. AMM TASK 79-00-00-281-805).
(b) If there is an oil-chip ECAM alert:
1 Fully apply the task (Ref. AMM TASK 79-00-00-281-805), included the figure (Flow Chart Decision vs Magnetic Particle).
(4) Do a check of the A, B and C sumps, and the accessory gearbox and transfer gearbox sumps scavenge screen plugs (Ref. AMM TASK 79-00-00-200-806).
