# How do I determine if the module is faulty?

If you are receiving codes from other modules indicating "Loss of communication from the SRS module," typically represented as U-codes, and you have verified that all fuses are intact, you may need to check the power and ground connections to the module. If both power and ground are confirmed to be good, it is highly likely that the module itself is faulty.
