Diagnostic Aids

WARNING: This page is about a different car, the 2015 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

This DTC can only be retrieved from the radio. The telematics communication interface control module does not set this DTC.
The radio only monitors the connection between the navigation signal splitter and the radio. The radio 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.
