What is the function of the HOWO steering wheel MEM button?

The MEM button on the steering wheel can directly recall the memory of the cruise control for convenient selection. Here are the specific details: 1. Introduction to HOWO: HOWO is a model produced by Sinotruk Jinan Truck Co., Ltd., a subsidiary of China National Heavy Duty Truck Group, and is one of the main products of Sinotruk. The Chinese name on the certificate of conformity for HOWO vehicles produced by Sinotruk is Haoluo, but in daily communication, people generally refer to it as HOWO. HOWO is the English identifier for Haoluo. 2. Cruise Control: The Cruise Control System, abbreviated as CCS, is also known as the cruise control device, speed control system, or autonomous driving system. Its function is to maintain the vehicle speed automatically without the need to press the accelerator pedal after the driver sets the desired speed, allowing the vehicle to travel at a constant speed.

As a long-haul truck driver, the MEM button on the HOWO steering wheel is our considerate road companion. It primarily serves as a memory function key, allowing one-touch storage and recall of settings like driver's seat position and mirror angles. It's especially convenient when switching between my 185cm frame and my 160cm co-driver - just press the button and the seat automatically adjusts to position. The most practical feature is its linkage with seat heating/ventilation. On cold northern winter mornings, pressing MEM warms the seat toasty in three minutes. When tackling mountain passes in Yunnan-Guizhou-Sichuan routes, activating the lumbar support boost mode firmly anchors me in the driver's seat. I've heard the new models can even memorize AC vent directions and multimedia volume - this design truly understands our professional drivers' needs.

As a fleet manager frequently handling various heavy-duty trucks, the HOWO MEM button is essentially an intelligent memory system trigger. A short press switches between preset parameter groups for different drivers—for instance, new driver Xiao Wang prefers the steering wheel raised by 5cm, while veteran Li likes the seat positioned further back. Holding it for 5 seconds stores all current settings, even memorizing dashboard brightness. Our fleet tests showed driver switchover time reduced from 3 minutes to just 8 seconds. Notably, its fault protection mechanism flashes an indicator light upon detecting sensor abnormalities—last year during the rainy season, one truck's waterlogged memory module was promptly repaired thanks to this alert.

After three years of driving the HOWO, I found the most valuable feature of the MEM button is its scene memory. Press MEM-1 in the morning, and the seat automatically moves forward 2cm for easier clutch operation; switch to MEM-2 during highway cruising, and the seat reclines while the steering wheel rises to activate rest mode. On weekends when picking up the kids, you can even set a safety mode that automatically limits multimedia volume. Once, I lent the car to a relative, and with just one press of the MEM button upon return, all settings were restored—quicker than a factory reset on a phone. Now, among that row of buttons on the steering wheel, this round button with an 'M' is the one I use most frequently.

Over a decade of repairing trucks, the HOWO MEM button is backed by an entire LIN bus control system. When pressed, the ECU reads Hall sensor data from the seat motor, with the steering wheel angle sensor achieving an accuracy of 0.5 degrees. If the button fails, don't rush to replace the entire assembly—first check the 10A fuse at position F23 in the fuse box. A common issue is rainwater seeping into the connector along the wiring harness when opening the door on rainy days. The solution is to unplug the green connector under the A-pillar and spray it with electronic cleaner. Here's a handy tip for owners: holding down the MEM + horn button for 3 seconds can restore factory memory settings, saving a trip to the 4S shop.
