Where it lives

For U0151, the part to look at first is the module named here.

Check these first

• A failed Restraints Control Module
• Damaged wiring between the RCM and the vehicle computer
• A short or open on the RCM communication circuit
• A software fault in the RCM or ECU
• A poor ground at the RCM

What to do next

1. Check power and ground at the Restraints Control Module
2. Inspect the RCM wiring and connector for damage
3. Check the communication circuit for shorts or opens
4. Update the RCM and ECU software
5. Replace the RCM if it does not answer
6. Clear the code and retest
