DTC B2470 04: Cellular Phone Antenna Circuit Malfunction Open Circuit
The cellular antenna is connected to the communication interface module (CIM) with a RG-58 coax cable. The CIM polls the data from the cellular antenna once every second.
Circuit/System Testing
Ignition OFF, disconnect the cellular antenna coax from the CIM module and the cellular antenna.
Ignition ON, test for less than 1 volt between the antenna coax center terminal and ground.
? If greater than the specified range, replace the antenna coax.
Ignition ON, test for less than 1 volt between the antenna coax outer shield and ground.
? If greater than the specified range, replace the antenna coax.
Test for infinite resistance between the antenna coax center terminal and ground.
? If less than the specified value, replace the antenna coax
Test for infinite resistance between the antenna coax outer shield and ground.
? If less than the specified value, replace the antenna coax
Test for less than 5 ohms at the cellular antenna coax center terminal from end to end.
? If greater than specified value, replace the cellular antenna coax cable.
Test for less than 5 ohms at the cellular antenna coax outer shield from end to end.
? If greater than specified value, replace the cellular antenna coax cable.
Test for infinite resistance between the antenna coax center terminal and the outer shield.
? If less than specified value, replace the cellular antenna coax cable.
If coax cable tests normal, replace the cellular antenna.
Clear the DTCs and operate the vehicle within the conditions for running the DTC. Verify DTC B2470 does not set.
? If the DTC sets, replace the CIM.
