What does the CH on the dashboard mean?

[DeJude]

The CH on the dashboard refers to the coolant temperature gauge. The temperature range is from C to H, where C represents 60 degrees. Once the needle reaches C, it indicates the coolant temperature has reached 60 degrees. H represents 110 degrees, and the temperature can be estimated based on the span from 60 to 110 degrees. The reasons for excessively high coolant temperature are: 1. Insufficient coolant due to low fluid levels or leaks; 2. Abnormal cooling caused by a malfunctioning radiator fan; 3. Abnormal circulation cooling due to a faulty water pump; 4. Engine issues or cooling system failures. The reasons for excessively low coolant temperature are: 1. Damaged thermostat; 2. Continuously running radiator fan.

I've been driving on the road for over twenty years, and I always pay extra attention when the 'CH' symbol lights up on the dashboard. This usually indicates a problem with the charging system, meaning the alternator can't charge the battery. I remember once during a long-distance trip when this light came on, I immediately pulled over to check and found a crack in the alternator belt. This situation is particularly dangerous because the car might suddenly stall while driving, and even the steering wheel could lock up. I recommend turning off power-consuming devices like the air conditioner and stereo immediately and finding a nearby repair shop. Don't push through to your destination—I have a friend who ignored it and ended up calling a tow truck on the highway at night, costing over 800 just for the rescue fee.

During my last road trip, the dashboard suddenly displayed a 'CH' warning, and I was so startled that I almost spilled my milk tea on the steering wheel. Later, I learned it was a charging warning, indicating the battery was running low! In my panic, I fumbled through the owner's manual and discovered that prolonged driving could cause the headlights to dim or even the engine to stall. Thankfully, I managed to exit the highway in time and found a repair shop. The mechanic said the issue was caused by worn-out generator brushes leading to abnormal charging. This kind of fault is particularly sneaky, so I recommend all my fellow drivers to get into the habit of checking the dashboard while warming up the car—red or yellow warning lights should always be taken seriously.

Having worked in an auto repair shop for ten years, I often encounter car owners pointing to the 'ch' indicator on the dashboard for consultation. Simply put, it indicates a fault in the vehicle's charging circuit, possibly due to poor wiring contact or a damaged generator rectifier. At this point, using a multimeter to measure the battery voltage can confirm the issue if it reads below 13 volts. Last summer, there were particularly many such failures because high temperatures accelerate the aging of electronic components. What worries me most is when car owners don't take it seriously. For example, a Touareg continued to drive 60 kilometers with the warning light on, resulting in over 5,000 yuan spent on replacing the battery, generator, and towing fees.

During discussions in the car enthusiast group, I noticed many members misunderstand the 'ch' indicator on the dashboard. In fact, this code specifically indicates a charging system fault. I've studied repair manuals for over 50 vehicle models. The most common cause is a damaged alternator regulator leading to voltage instability. Like the Magotan owner in our group last week - they kept driving to the supermarket after the 'ch' light came on, only to find the battery completely dead at checkout. My advice: immediately check belt tension and battery terminals when seeing this warning, and call roadside assistance if necessary.
