Troubleshooting Recommendations:
CAUTION: DO NOT DO ELECTRICAL CHECKS INTO THE ENGINE ELECTRONIC CONTROLLER (EEC). IF YOU DO NOT OBEY THIS INSTRUCTION, DAMAGE TO THE EEC CAN OCCUR.
- Perform a visual inspection of the interface wiring and connectors for damage between the connectors L44P1 and P1043.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Perform wiring checks between ICU (L44P1) and Fixed Cowl Interface (2JA2).
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Perform wiring checks between Bypass Disconnect (P1116) and Fixed Cowl Interface (2PA2).
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Perform wiring checks between Bypass Disconnect (J1116) and Right EEC (P1043).
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Perform a check of the insulation resistance of the interface connectors ICU (L44P1), Bypass Disconnect (P1116) and EEC (P1043).
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Swap Right EEC with Left EEC.
- If system checks are good, replace Right EEC and do close out.
- If fault remains, continue with next step.
- Replace ICU.
- Do close out.
