Lost Communication With Restraints System Sensor K

Where it lives

For U017A, the part to look at first is the sensor named here.

Check these first

• Wiring damage between restraints sensor K and the computer
• A faulty restraints system sensor K that stops reporting
• Water or corrosion in the sensor K connector
• A restraints module fault that drops the sensor K channel

What to do next

1. Inspect the sensor K harness and connectors for damage
2. Dry and clean any corroded connector at sensor K
3. Monitor sensor K communication on a scan tool
4. Check the restraints module for stored companion codes
5. Replace restraints sensor K if it does not respond
6. Clear the code and retest
