As someone who frequently tinkers with vehicles, I often encounter the C1122 fault code on Suzuki SX4 models, which is usually caused by an issue in the brake light switch circuit. This component is located near the pedal, and aging or water ingress can lead to unstable signals, resulting in brake lights not illuminating when the pedal is pressed or the ABS warning light coming on. In severe cases, starting the car can become difficult, and worse yet, other drivers won't see your brake lights, significantly increasing the risk of rear-end collisions. It's recommended to immediately check the status of the brake lights. If any abnormalities are found, visit a repair shop to confirm with a diagnostic tool—replacing the switch or repairing the wiring is both low-cost and safe. Regular maintenance, such as keeping the switch clean, can prevent such issues. Don't let minor neglect lead to major driving hazards.

I once drove an SX4 model and encountered the C1122 code. After checking the information, I found it pointed to a brake sensor malfunction. It could be caused by poor switch contact or damaged wiring harness, leading to brake light failure or false alarms from the auxiliary system. At that time, my lights were intermittently working, and the mechanic fixed it by replacing the part—the whole process wasn't complicated. If you notice this issue, don't hesitate to act, as driving at night becomes much riskier. I recommend taking the car for inspection. The cost is usually under 200 yuan, and it's a good idea to check the fuse as well to ensure everything is in order before hitting the road.

Buddy, the C1122 code on the SX4 is usually just a brake switch issue, pretty common. Electrical faults can cause brake lights to fail or trigger false system errors, compromising safe handling. I've done some basic diagnostics myself—an OBD scanner can reveal details, but most cases just require replacing the worn-out switch. Fixing it won't break the bank, but ignoring it could mess with the ABS function. Don't gamble; get it sorted at the shop ASAP. It won't affect the engine, but it's literally a lifesaver.
