Displaying letters such as prnds indicates the gear positions of an automatic transmission car. Introduction to automatic transmission gears: Generally, automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L. Driving an automatic transmission car only requires the use of the parking gear (P), reverse gear (R), neutral gear (N), and drive gear (D) to meet the needs of regular driving. However, in some special driving conditions, other functional gears may be needed. Notes on automatic transmission gears: P gear: Parking gear, used when the car is parked and not in use. In this position, the wheels are mechanically locked to prevent rolling. R gear: Reverse gear, used for reversing. N gear: Neutral gear, used for temporary stops (such as at a red light). Note that this gear indicates neutral, and to prevent the car from rolling on a slope, the brake must be applied.

While driving, I noticed the PRNDS display on the dashboard and checked the manual. It turns out this is a transmission gear position indicator symbol: P stands for Park, R for Reverse, N for Neutral, D for Drive, and S usually indicates Sport mode. But strangely, it kept flashing continuously, and the vehicle had obvious jerking sensations. I suspected it might be a problem with the gear position sensor—either aging wires causing inaccurate signals or a short circuit in the transmission control module. Thinking back to last summer when there was a strange smell from the air vents, I ignored it, only to face a troublesome repair later. This time, I went straight to the 4S dealership. They scanned the codes with a computer and found that false signals were caused by sensor wear. After the repair, the issue never recurred. I recommend addressing such problems early to avoid being stranded on the road. Though it may seem minor, it’s crucial for driving safety—don’t procrastinate like I did.

Last week, after starting my car, the PRNDS indicators suddenly turned gray. While driving on the highway, I couldn’t engage the D gear and could only move at low speed, which was really frightening. I think it’s similar to the common issue of a burnt-out bulb—most likely caused by poor wiring contact or oxidation of the switch contacts. I tried restarting the engine myself, but the problem didn’t go away. Later, when the mechanic checked it, he said that an overheated transmission electronic module or a faulty relay could also trigger this display. The repair took half a day, but it made me realize the importance of regular wiring maintenance. After driving for ten years, this minor malfunction taught me to pay attention to dashboard warnings and not wait for major issues to regret it—safety always comes first.

If you notice abnormal PRNDS display, such as flickering or unclear indicators, don't take it lightly as it may signal transmission malfunction. The most common causes are sensor failure or unstable voltage - seemingly simple yet dangerous issues, just like a blown headlight fuse. I've experienced this before when my car shook violently; I immediately pulled over, turned off the engine, and called a tow truck. The repair shop diagnosed it as a short circuit in the gear controller. If left unfixed, this problem could lead to loss of control at high speeds, endangering both yourself and others. Since then, I've made it a habit to glance at the dashboard before every startup to ensure everything's in order.
