What is the KL15 line?

KL15 represents the engine ignition signal (corresponding to the IGN state of the car key), and also indicates the signal for turning the key to start the car. Most ECUs require the car to be in the started state to operate, such as the ECUs of the chassis system, ABS, ESP, ABM, etc. KL15R (R stands for Radio) is when the key is turned to the position where the radio works (corresponding to the ACC state of the car key), but the car has not yet started, for example, the dashboard and windows receive this signal. This signal is powered by the ZentraleElektrik (the main electrical box in the car), and is connected to the KL15 pins of each ECU through a fuse. KL30 is the ECU power supply (i.e., connected to the car battery), providing the operating voltage for the ECU, generally between 11V and 15V. Some ECUs can operate when the car is turned off (corresponding to the OFF state of the car key), such as the Body Control Module (BCM). KL31 is the ECU ground source. The KL31 signal is connected to the common ground terminal of the car, usually marked with a W, such as W4 indicating the ground terminal of the engine shield. There are usually several common ground terminals in a car, located near the engine, dashboard, undercarriage, roof, and rear compartment, used for ECU common grounding to maintain consistent ground voltage.

How Many Years Can Bodywork and Painting Last?

Bodywork and painting with poor technique and improper maintenance may develop issues within 1-2 years; with good technique and proper maintenance, it can last around 5-6 years. Inspection After Bodywork and Painting: Check the paint: After bodywork and painting repairs, inspect the smoothness of the paint and check for impurities such as pinholes or bubbles. During the repair process of body panel coatings, it is inevitable for some impurities and dust to be present in the air. If not handled properly, this dust can adhere to the paint. Check for color difference: After car painting, it is difficult to detect color differences between the new paint and the original paint. Even with better craftsmanship, it is challenging to achieve a perfect match with the original paint. When checking for color differences, perform the inspection in a bright environment to ensure a comprehensive evaluation. Check the gloss of the clear coat: The clear coat is the outermost transparent layer of the car paint. If the gloss of the clear coat is poor, it will affect the visual appearance. Before performing bodywork and painting, ensure the cleanliness of the bodywork's filtration system and check if the spraying pressure is normal. If these aspects are satisfactory, proceed to inspect the paint booth's water and micro-dust separator and the air compressor. This step requires the paint hoses to remain clean. Bodywork and painting have high requirements. Items such as paint hoses, paint mixing cans, and spray guns used during the process should be stored in clean areas. Besides maintaining cleanliness, all preparatory steps should be completed outside the paint booth before starting the painting process to avoid unnecessary contamination of the paint.
