Testing procedure
Testing of the install will require the installer to have access to a Power down plug and a
Communication/GSM Diagnostics plug for the FM 3xxx. These are the same tools used for standard FM
diagnostics and they can be programmed using the Dealer Utility application. See Appendix A
Note:
The FM needs the internal SIM and modem to be operational during this process. Make sure it is still
operational and remains installed during the test.
