Troubleshooting Recommendations:
- Perform the deactivation of the Thrust Reverser and open the cowls.
- Visually check the filter differential pressure pop-up indicator (at the bottom of filter) as per Engine Manual (EMM 79-34-02-210-801).
- If the pop-up indicator is not extended, go to step 4.
- If the pop-up indicator is extended, continue with next step.
- Perform a detailed Inspection of the Oil filter element as per Engine Manual (EMM 79-21-02-220-801).
- If the oil filter element inspection is satisfactory, go to step 6.
- If the oil filter element inspection is not satisfactory, replace the oil filter element and go to step 7.
- Perform wiring checks between the Oil Filter DP Switch (P1069) and the EEC 2 (P1046).
- If wiring checks are not good, repair defective wiring as required and go to step 7.
- If wiring checks are good, continue with next step.
- Swap EEC 2 with EEC 1. Is the fault still present?
- If NO, replace EEC 2 and go to step 7.
- If YES, continue with next step.
- Replace the Oil Filter DP Switch.
- Close the cowls and activate the thrust reverser.
- Do close out.
