Troubleshooting Recommendations:
- Check door rigging, including distortion, debris or damage around the TR door.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Check primary lock actuator and mechanism for sign of corrosion or binding.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Perform a continuity check on connector as follows. Shall have continuity when TR door is stowed.
From To Result P7004-1 P7004-2 P7012-1 P7012-2 - If there is no continuity, repair defective wiring as required and do close out.
- If there is continuity, continue with next step.
- Perform wiring checks between door stow switch and EEC.
- 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 Right EEC.
- Do close out.
