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:
- 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.
- Open the cowls.
- Remove the applicable bypass-duct access panel and the applicable compressor fairing.
- Perform wiring check between the EEC 2 connector (P1047), the bypass duct connector (J1032) and the VSVA connector (P1010).
- 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 the Right EEC with Left EEC. Is the fault still present.
- If NO, replace Right EEC and go to step 7.
- If YES, continue with next step.
- Replace VSVA.
- Close the cowls.
- Perform a activation of the thrust reverser.
- Do close out.
