| Diagnosis and Testing Refer to Wiring Diagrams Section 415-01, for schematic and connector information. Worldwide Diagnostic System (WDS) (418-F224). Principles of Operation Diversity Antenna The audio unit has the facility to receive the input of two antennae. Sensors within the audio unit calculate which of the antenna signals is the strongest and uses this signal to improve the reception for the listener. The first antenna is the original vehicle antenna fitted on the roof at the front of the vehicle. The second antenna is integrated into the rear window glass on all vehicles except wagon. On the wagon the second antenna is integrated into the right-hand rear quarter window glass. It is connected to the audio unit by a cable. Inspection and Verification NOTE:If the code is entered incorrectly 3 times, the system will lock out. The component can only be unlocked by the manufacturer. - Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.
