Fault Description:
There is an error of resistance or an open or short circuit in the Linear Variable Differential Transformer (LVDT) of the Variable Stator Vane Actuator (VSVA) for the Engine Electronic Controller (EEC) 2 channel B. Inhibited during Take-off and Landing.
Possible Causes:
- Right Variable Stator Vane Actuator (VSVA)
- Right Engine Electronic Controller (EEC)
- Associated Wiring
Troubleshooting Tips:
Advisory Wire/Service Bulletin: None
Forum Articles/Infoservice/Newsletter: None
NOTE: The VSVA circuits are continuously monitored during engine operation and during power-up of the FADEC.

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 deactivation of the Thrust Reverser (TR) and open the cowls.
- Remove the applicable bypass-duct access panel and remove the applicable compressor fairing.
- Perform wiring check between EEC 2 (P1047), the bypass duct (J1032) and the VSVA (P1010).
- If wiring checks are not good, repair defective wiring as required and go to step 6.
- If wiring checks are good, continue with next step.
- Replace the VSVA.
- If system checks are good, go to step 6.
- If fault remains, continue with next step.
- Replace EEC 2.
- Install the applicable bypass-duct access panel and the applicable compressor fairing.
- Close the cowls and activate the thrush reverser.
- Do close out.
