| DTC Code | DTC Name |
|---|---|
| B1573 | Disconnect/Short in Telephone Antenna Circuit |
| B15CB | Telephone Antenna Disconnected |
DESCRIPTION
These DTCs are stored when a malfunction occurs in the roof antenna assembly.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| B1573 | Disconnect/Short in Telephone Antenna Circuit | Roof antenna assembly impedance (Ω) is lower than the malfunction threshold for 20 seconds when the engine switch is on (IG). (Short circuit) |
|
| B15CB | Telephone Antenna Disconnected | Roof antenna assembly impedance (Ω) is higher than the malfunction threshold for 20 seconds when the engine switch is on (IG). (Open circuit) |
|
CAUTION / NOTICE / HINT
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Registration for Telematics System.
