Service Notes

NOTE:
- If the ignition switch is turned ON with the airbag sensor assembly connectors disconnected, or if a vehicle battery is removed with the ignition switch ON, the system will determine this condition as a failure and it will automatically call the call center. When an accidental call is made automatically, access to the call center and ask them to cut off the line.
- To prevent this, perform the following when working on operation related to the airbag sensor assembly or battery:
- Disconnect the connectors of the mayday ECU and the back-up battery before disconnecting the airbag sensor assembly connector.
- Be sure that the ignition switch is OFF when removing a vehicle battery.
- If not signal has been received from the airbag sensor assembly since the ignition switch was turned ON, a service call will be made.
- If good signal reception from the airbag sensor assembly after the ignition switch ON is interrupted, an emergency call will be made.
