What it does

• Diagnoses vehicle antenna systems (radio, GPS, keyless entry, TPMS, etc.)
• Checks signal quality, communication, and antenna connectivity
• Identifies faults in antennas, wiring, or related control units

When it is required

• When radio, navigation, or GPS reception is poor
• When keyless entry or remote functions are unreliable
• After antenna replacement or body repairs
• When communication-related fault codes are stored

Conditions that must be met

• Ignition ON
• Vehicle stationary
• Stable battery voltage
• Diagnostic tool connected
• Antenna system accessible for testing

What happens during diagnosis

• Signal strength and antenna status are evaluated
• Control units check communication with antenna modules
• Wiring continuity and power supply may be tested
• Fault locations are identified and logged

If diagnosis is not performed

• Communication issues may remain unresolved
• Reduced functionality of comfort and navigation systems
• Persistent fault codes or warning messages

After diagnosis
