Supplemental Restraint Systems

Faults – No Communication

This means the diagnostic computer cannot establish communication with the airbag module. This could be due to in-compatible diagnostic tooling, or it could be because the module is not powered up which could be caused by a bad earth or no power feed to the module. You should ensure the ACM is bolted down with any earth straps attached and it is receiving an earth. Also check that the appropriate wire at the module is receiving battery voltage.
