• An internal failure of the Restraints System Sensor L
• Loss of power or ground at the Restraints System Sensor L
• A fault inside the Restraints System Sensor L
• An incorrect Restraints System Sensor L that does not match the vehicle

What to do next

1. Scan every module and record the stored codes
2. Check Restraints System Sensor L data on live data
3. Check the Restraints System Sensor L circuit for opens and shorts
4. Check the power and ground feeds to the Restraints System Sensor L
5. Replace the Restraints System Sensor L if the circuit and grounds test good
6. Clear the code and retest
