Diagnostic Aids

This DTC can only be retrieved from the human machine interface control module. The telematics communication interface control module does not set this DTC.
The human machine interface control module only monitors the connection between the navigation signal splitter and the human machine interface control module. The human machine interface control module cannot detect faults between the signal splitter and the navigation antenna. Faults between the signal splitter and the navigation antenna will result in a loss of GPS signal without setting DTC B2462.
The navigation antenna requires a clear line of sight to the sky to operate properly. The GPS may have limited, intermittent, or no reception near tall buildings or inside structures.
