This genuine HOWO integrated door and window system is engineered for driver convenience and vehicle security.
When you choose authentic Howo Parts, you receive the complete integrated door and window system with left and right door controllers plus remote controls.
The Hohan integrated left door controller (Standard version) is the master control unit mounted on the driver side door panel. This controller manages all electrical functions for the left door, including power window lifting, central locking actuation,
side mirror adjustment, and memory settings. It communicates with the right side controller via a dedicated CAN bus line. The controller housing is sealed against dust and moisture, ensuring reliable operation in humid and dusty environments typical of African roads. The surface features intuitive backlit buttons that are easy to locate at night.
The Hohan integrated left door controller also includes a child lock override and window anti pinch protection, enhancing safety for all cab occupants. Its plug and play design matches the factory door harness, requiring no wire cutting or splicing during replacement. The standard version is compatible with all HOWO MAX 4X2 tractors produced from 2019 onward.
The HOWO NX integrated right door controller (Standard version) is the companion unit for the passenger side. It mirrors many functions of the left side but with a simplified layout focused on passenger convenience. This controller provides independent window control, door lock/unlock, and a lockable window disable switch for the driver. The HOWO NX integrated right door controller is built with the same high grade engineering polymers and sealed electronic components as the left unit.
Its wiring harness connects directly to the central body control module, allowing two way communication for functions such as window global opening/closing via the remote key.
The right controller also features an ambient LED indicator that shows door lock status at a glance. This component is crucial for maintaining balanced electrical architecture in the integrated door and window system, and its standard version offers all core functions without unnecessary complexity, making it ideal for fleet vehicles where durability and simplicity are paramount.
The remote control is a compact wireless transmitter that works with the integrated door and window system to provide keyless entry and remote window operation. Two remote controls are supplied with the kit, each containing a rolling code security chip that prevents unauthorized code grabbing.
The remote control buttons allow locking and unlocking of all doors, as well as remote lowering of the front windows for cabin ventilation before entering. A long press on the lock button also closes any open windows, a valuable feature when parking in dusty or rainy conditions. The remote control operates on a standard 12V battery and has a range of approximately 50 meters in open areas.
The ergonomic housing is resistant to impact and moisture, and each remote includes a detachable key blade for manual door access in case of electronic failure. The remote control is fully pre programmed to match the integrated door and window system, so installation requires only battery insertion and system synchronization, which is a simple procedure using the left door controller sequence.

The integrated door and window system communicates directly with the vehicle central body controller via CAN bus. This allows features such as automatic window closing when locking the cab, and remote window opening from the key fob. The system also provides real time diagnostic feedback for quick troubleshooting.
Both door controllers incorporate current sensing anti pinch protection. If the window motor encounters resistance while closing, it automatically reverses direction to prevent injury or damage. This feature is especially important for vehicles used in family or team driving operations.
The integrated door and window system draws less than 1 mA when the vehicle is parked, preventing battery drain during long idle periods. The remote control receiver remains active but consumes minimal energy. This ensures reliable starting even after weeks of storage.
The left door controller buttons are arranged in a natural curve that falls under the driver’s fingers without looking. The raised tactile markers allow blind operation while keeping eyes on the road. The right controller is similarly intuitive for passengers, reducing driver distraction.
The integrated door and window system is designed specifically for the HOWO MAX 4X2 cab electrical architecture. It connects directly to the existing door harness connectors, eliminating any need for wire cutting or soldering. The system also works with the standard central locking actuators and window regulators already installed in the doors.
Because the controllers are pre programmed with the correct CAN ID and function mapping, installation is a simple swap of the original door modules. This plug and play design reduces workshop labor time and eliminates programming errors.
Each component of the integrated door and window system has undergone rigorous environmental testing. The door controllers have been subjected to vibration levels of 10g for 200 hours, simulating the harsh conditions of laterite roads and highway expansion joints. They have also passed salt spray exposure of 500 hours, ensuring reliable operation in coastal humidity.
The remote control has been drop tested from 1.5 meters onto concrete and remains fully functional. All electronic components are conformally coated to resist moisture and dust ingress, a critical requirement for trucks operating in dusty or rainy regions of Nigeria.
Start by disconnecting the battery ground cable. Remove the existing door trim panels on both sides. Unplug the original door controller connectors.
Install the Hohan integrated left door controller in the driver side, aligning the mounting brackets with the original screw holes. Connect the factory harness to the controller, ensuring all latches click securely. Repeat the same for the HOWO NX integrated right door controller on the passenger side. Reinstall the door trim panels.
Insert the batteries into the remote controls and synchronize them by pressing the lock and unlock buttons simultaneously within 30 seconds of connecting the battery. Test all functions: window up/down from each switch, door lock/unlock from each controller and remote, and mirror adjustment if equipped. If any function does not work, check the CAN bus connector seating.
This integrated door and window system is compatible with all HOWO MAX 4X2 standard and sleeper cab variants. It works with both manual and automatic window regulator mechanisms, as well as electric mirror adjustment systems. The standard version controllers lack the memory seat and mirror position memory functions found in premium versions, but they provide all essential daily controls.
For vehicles with sunroof or additional lighting options, the system provides spare control outputs that can be enabled via diagnostic tool. The remote control is compatible with the standard keyless entry receiver integrated into the cab body control module.
Inspect the door controllers and their connectors during routine cab maintenance every 50,000 kilometers. Check for any moisture inside the connector boots or corrosion on the pins. If a window becomes slow or noisy, verify that the anti pinch calibration is still correct. To recalibrate, lower the window fully, then raise it while holding the switch until it fully closes and clicks.
The remote control battery should be replaced annually; a weakening signal range indicates a low battery. Do not attempt to disassemble the controllers as they are sealed units. If a controller fails, replace the entire unit with a genuine HOWO part to maintain system integrity.
If a window does not respond, first check the 20A fuse for the door module. If the fuse is intact, unplug the controller and reconnect it after 30 seconds to reset the internal processor. If the remote control does not work, replace the battery and resynchronize by pressing the lock button four times within 10 seconds.
If only one door controller is unresponsive, inspect the CAN bus wiring between the two doors; a broken or pinched wire will interrupt communication. The system stores fault codes that can be read with a generic OBD2 scanner; a code for CAN bus time out indicates a wiring issue.
If the left controller works but the right does not, try swapping the controllers temporarily to isolate a defective unit. Always use genuine replacement parts when repairing the integrated door and window system.
Aftermarket door controllers often lack proper CAN bus handshake protocols, leading to intermittent errors or ghost unlocking. Their remote controls may use fixed code technology that can be easily cloned, compromising vehicle security. The plastic housings of generic units are not UV stabilized and can become brittle after a few months of sunlight exposure.
The genuine HOWO integrated door and window system uses industrial grade microcontrollers, rolling code encryption, and UV resistant materials. Every component is tested for electromagnetic compatibility to prevent interference with the truck’s ABS or engine electronics.
The price difference between genuine and aftermarket parts is quickly offset by reduced failure rates and higher driver satisfaction. For fleet operators, standardizing on genuine components also reduces spare parts inventory complexity.
The integrated system reduces the number of separate electronic modules previously required for door functions, lowering the overall weight of the vehicle by approximately 0.5 kg and reducing manufacturing material consumption. The low power standby mode also contributes to lower fuel consumption by decreasing alternator load when the engine is running.
All plastic components are marked with recycling codes and are free from harmful substances such as lead and cadmium. The remote control batteries are standard lithium coin cells that can be recycled through proper disposal channels. Choosing genuine HOWO parts supports environmentally responsible manufacturing processes that comply with ISO 14001 standards.
