Troubleshooting Recommendations:
- Check if there is damage to the sensor and nose gear harness.
- If there is damage to the sensor or harness, replace the LH nose gear harness and do close out.
- If there is no damage, continue with next step.
- Check if there is damage to the LH WOFW sensor target.
- If there is damage to the WOFW sensor target, replace the target and do close out.
- If there is no damage, continue with next step.
- Perform the adjustment of the nose-gear weight-off-wheels (WOFW) proximity-sensor AMM task 32-61-05-820-807. Is the fault still present?
- If NO, do close out.
- If YES, continue with next step.
- Access and disconnect the Left NLG WOFW Sensors. Perform a continuity check as follows:
From To Result PW1-V PW1-U - If there is no continuity, replace the LH nose gear harness and continue with the next step.
- If there is continuity, continue with next step.
- Perform a continuity check as follows:
From To Result A52AP1-J3 P214-87 A52AP1-K3 P214-88 J214-87 JW1-V J214-88 JW1-U - If there is no continuity, repair defective wiring as required and do close out.
- If there is continuity, continue with the next step.
- Perform a continuity check as follows:
From To Result A52AP1-J3 Ground A52AP1-K3 Ground - If there is continuity, repair defective wiring as required and do close out.
- If there is no continuity, continue with next step.
- Replace the Left WOFW sensor and target.
- Do close out.
