When the PLE641 system develops a "Cellular Radio Does Not Commmunicate"" situation, certain steps can be taken before traveling to the customer site. Follow the steps from the "Off-Site Diagnostics" in order to help determine the fault before traveling to the customer site.Off-Site Diagnostics
Note: Some steps of the "Off-Site Diagnostics" sections are dependent on the customer being on site.
Verify that the PLE641 system is in a location where cellular phone service should be available.
If cellular service is not readily available, the cellular radio will not able to communicate. Have the customer move the asset to a location where cellular service is available.
If cellular service is available, proceed to Step 2.
Request the location of the machine. With the customer at the location of the asset, the following questions may or may not be answered. Ask the customer if the asset is powered ON, and located where the radios have clear line of sight to the sky.
If the asset was inside of a building, under/next to a large obstacle, or has the battery power OFF, have the customer do the following:
Turn the key power ON if the power was OFF.
Attempt to move the asset to a more open location with a clear line of sight to the sky.Select the "Refresh" on the equipment page in Product Link Web.
If the equipment was ON, and in a good location for data transfer, have the customer check to see if the radio disable switch was disabled. The radio disable switch is a switch between the control module and radios. When the radio disable switch is enabled, the power to the radios is off. If the radio disable switch was enabled, then have the customer disable the radio disable switch, and attempt a "Refresh" on the equipment page in Product Link Web.On-Site Diagnostics

Service tool connects. Proceed to Step 2.
Check for any active or logged diagnostic codes.
If diagnostic codes are present, proceed to the diagnostic information for that specific code.
If diagnostic codes are not present, proceed to Step 3.
Perform the "Communication Check".
If the "Communication Check" is successful, return the asset to service.
If the "Communication Check" fails and the "Service Dashboard" screen shows that the cellular radio has "No Connection", proceed to Step 4.
