The TV antenna signal circuits consists of 4 individual coaxial cables that carry the TV signal information received by the TV antenna through the TV antenna amplifier to the TV antenna module.
• | Ignition ON. |
• | Battery voltage must be between 9-16 volts. |
The TV antenna module detects a open or short to ground on one or more of the 4 TV antenna coax cables for 20 seconds.
The TV antenna module disables all 4 coax cables when a short to ground is detected. When the TV antenna detects an open/high resistance in one or more TV antenna coax inputs, the unaffected TV antenna coax inputs will continue to operate.
• | The condition responsible for setting the DTC no longer exists. |
• | The DTC clears after the TV function has been cycled OFF then ON. |
