Troubleshooting Recommendations:
- Swap FCU 2 with FCU 1. Is the fault still present?
NOTE: Prior to swapping FCUs, clear both FCU latched faults. Make sure that the FCUs have gone through the complete Built-In Test with all hydraulics systems pressurized and wait 30 seconds after the 'SPLRS STAB IN TEST' CAS message is cleared.- If NO, replace FCU 2 and do close out.
- If YES, continue with next step.
- Perform a wiring check between FCU 2 (A66BP1)/(A66EP1) and RTL position transducer 2 (MT168P1).
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Replace RTL position transducer 2.
- Do close out.
