What does the 'R' on the HOWO dashboard mean?

The 'R' light on the car dashboard is the tire pressure deficiency warning light. When this light comes on, it indicates that the tire pressure of one of the car tires is insufficient and needs to be replenished. Tire pressure is the blood pressure of a car, and the level of tire pressure plays a crucial role in the car's performance and power. Both excessively high and low tire pressure can be harmful to the car. Below are the specific reasons why the 'R' yellow light flashes on the HOWO dashboard: 1. False fault: A fault code is reported, but the car operates normally. It might be due to an operation that exceeded the computer's control range, resulting in a fault code feedback from the computer. The fault code can be cleared first to see if it reappears. 2. Intake pressure sensor fault: The engine does not show any particularly obvious faults. Based on computer detection information and further checks, it is necessary to determine if there is a fault that does not affect normal driving or has minimal impact, but should be identified and resolved promptly. For example, an intake pressure sensor fault. 3. Oxygen sensor fault: Such faults can be felt through visual inspection and driving experience and severely affect the normal operation of the engine, requiring immediate repair. For example, obvious lack of engine power is likely due to an oxygen sensor issue.

Recently, while driving my HOWO truck, an 'R' symbol suddenly appeared on the dashboard. At first, I was startled, thinking it was a fault code and worried that vehicle issues might delay my delivery. Later, after checking the manual, I realized that 'R' stands for Reverse gear. It illuminates when you shift into reverse mode, reminding you that the vehicle is in backing state. This is completely normal - you'll see it flashing when reversing into parking spaces or making U-turns. However, be cautious if it remains lit while driving forward or in neutral, as this might indicate problems with the gear position sensor or wiring, requiring a visit to the repair shop. Driving safety is paramount - never ignore these small alerts to avoid collisions when reversing, especially during nighttime when visibility is poor. It's best to combine it with reverse radar operation in such conditions.

As a seasoned long-haul trucker, I know the R indicator on the HOWO dashboard is the standard display for the Reverse gear. It should illuminate when you shift into reverse, helping confirm the current operating mode. I've seen many novice drivers mistake this indicator for a major issue, but it's perfectly normal when used correctly. However, if it lights up unexpectedly - like when the vehicle is stationary - it might indicate a transmission sensor malfunction or poor contact, requiring prompt inspection to prevent potential hazards. Truck driving carries high risks, so paying attention to these details enhances safety and reduces accidents. I always make it a habit to check all indicator lights during startup to ensure everything's functioning properly, avoiding breakdowns that could delay deliveries.

From a technical perspective, the R indicator on the HOWO dashboard is part of the electronic system, signifying the Reverse status. It activates and illuminates when you shift into reverse gear. The system relies on sensors to detect the transmission position and sends signals to the dashboard. If it remains lit without operation, there may be a loose connector or controller malfunction. You can try restarting the vehicle, as sometimes a simple reset restores normal function. However, electronic components are prone to errors after wear. It's advisable to schedule a professional inspection to maintain system stability and reliability, especially for long-distance transport—don't take it lightly.
