Invalid Data Received From Side Obstacle Detection Control Module D

Where it lives

For U0550, the part to look at first is the module named here.

Check these first

• Electrical noise on the data bus corrupting the side obstacle detection control module D signal
• A low battery or charging fault that browns out the side obstacle detection control module D
• A fault inside the side obstacle detection control module D itself
• A loose, corroded, or water damaged connector at the side obstacle detection control module D
• An open or short in the side obstacle detection control module D wiring to the module that receives its data

What to do next

1. Scan all modules and record the stored and pending network codes
2. Test the side obstacle detection control module D power and ground feeds under load
3. Check the side obstacle detection control module D data bus wiring for opens, shorts, and chafing
4. Confirm the side obstacle detection control module D reports correct live data on the scan tool
5. Repair or replace the side obstacle detection control module D if the circuit, power, and bus tests pass
6. Clear the code and retest to confirm the side obstacle detection control module D fault is gone
