TEKONSHA 119251 ZCI Zero Contact Interface Universal ModuLite & Installation Kit

1. Wprowadzenie

The Tekonsha 119251 ZCI Zero Contact Interface Universal ModuLite is a power module designed to activate a trailer's stop, turn, tail, and running lights. This system operates by directly connecting to the tow vehicle's battery, utilizing sensors that snap over existing vehicle wires to detect electrical current. This design ensures absolutely zero contact with the tow vehicle's electrical system, eliminating the need for cutting or splicing wires. It is suitable for 12-volt vehicle systems only and works with both 2-wire and 3-wire vehicle systems.

4. Konfiguracja i instalacja

Installation of the Tekonsha 119251 ModuLite involves connecting the module to your vehicle's battery and attaching current sensors to the vehicle's existing wiring. This process avoids cutting or splicing, preserving your vehicle's electrical integrity.

4.1. Ogólne kroki instalacji:

1. Identify Vehicle Wires: Locate the vehicle's tail light, brake light, and turn signal wires. A multimeter can be used to identify the correct wires by testing for voltage changes when respective lights are activated.
2. Attach Current Sensors: Snap the provided current sensors over the identified vehicle wires. Ensure the sensors are oriented correctly as per the detailed instructions provided in the product's full installation manual. Incorrect orientation may lead to improper function.
3. Podłącz do akumulatora pojazdu: Connect the module's power wire directly to the vehicle's 12-volt battery, typically through a fused connection. Connect the ground wire to a suitable vehicle ground point.
4. Zamontuj moduł: Securely mount the ModuLite module in a suitable location, either inside or outside the vehicle, using the provided mounting hardware. Ensure it is protected from excessive moisture and heat.
5. Connect Trailer Wiring: Plug your trailer's 4-flat connector into the output of the ModuLite module.
6. Funkcjonalność testu: After installation, test all trailer light functions (tail lights, brake lights, left turn, right turn) to ensure proper operation.

For detailed, step-by-step instructions, refer to the comprehensive installation manual provided with your product. The process is designed to be straightforward, even for those without extensive electrical engineering experience.

5. Działanie

Once installed, the Tekonsha 119251 ModuLite operates automatically. The current sensors detect when the vehicle's lights (stop, turn, tail, running) are activated. Upon detection, the module draws power directly from the vehicle's battery to illuminate the corresponding trailer lights. This ensures that the trailer lights receive sufficient power for full brightness, regardless of the vehicle's electrical system load or sensitivity.

The module also adapts import and domestic vehicles with separate turn and stop lights (3-wire system) to standard trailer taillight wiring (2-wire system), simplifying compatibility. It is compatible with both LED and incandescent bulbs on both the tow vehicle and the trailer.

6. Konserwacja

The Tekonsha 119251 ModuLite is designed for durability and minimal maintenance. Regular checks can help ensure continued reliable operation:

• Sprawdź połączenia: Periodically check all wiring connections, especially the battery and ground connections, for corrosion or looseness. Ensure the current sensors remain securely snapped onto the vehicle wires.
• Module Condition: Inspect the module for any signs of physical damage. The robust design allows for interior or exterior mounting, but protection from extreme elements is always recommended.
• Zabezpieczenie przed przeciążeniem: The module features re-settable short circuit and overload protection. In case of an overload, the module will temporarily cease operation to protect itself and the vehicle. Once the fault is cleared, it should reset automatically.

7. Rozwiązywanie Problemów

7.1. Trailer Lights Remain On After Vehicle is Off

Some vehicle electrical systems may continue to provide a residual current, or the module may draw a small constant current, which can keep trailer lights illuminated or slowly drain the vehicle battery if left connected for extended periods.

• Rozwiązanie: To prevent battery drain, it is recommended to disconnect the 4-pin trailer connector from the module when the trailer is not in use. Alternatively, consider installing an inline switch on the module's power wire or removing the fuse when the vehicle is parked for long durations.

7.2. Trailer Lights Not Functioning or Incorrectly

If trailer lights are not working as expected (e.g., no lights, incorrect signals, dim lights), check the following:

• Sensor Placement and Orientation: Ensure each current sensor is correctly snapped onto the designated vehicle wire and that its orientation is correct. Refer to the installation manual for specific guidance on sensor direction.
• Połączenia zasilania i uziemienia: Verify that the module's power wire is securely connected to the vehicle's 12-volt battery and that the ground wire has a solid connection to the vehicle chassis.
• Sprawdzenie bezpiecznika: Inspect the fuse on the module's power wire. Replace if blown.
• Trailer Wiring: Ensure the trailer's wiring and lights are in good working condition and that the 4-flat connector is properly seated.
• Vehicle System Compatibility: Confirm your vehicle is a 12-volt system. While the module is universal, ensure no other vehicle-specific electrical issues are present.
