Product Description: The Heavy Truck Power Module Converter serves the crucial function of converting the truck's 24v K-Line communication protocol to 12v K-Line. This transformation is pivotal, as it allows seamless utilization of launch vehicle equipment without the risk of damaging the launch 12v diagnostic head. 24V to 12V Heavy Duty Truck Adapter for Launch X431 Function: 1. Convert the 24v voltage of the diagnostic interface of heavy trucks, light trucks, pickups, etc. into a 12v voltage that can be used by diagnostic equipment. 2. Convert The 24v truck k-line communication protocol into the 12v k-line communication protocol. 3. When inputting 24v voltage, the screen will display the input voltage as 24v, and the switch button pops up. When outputting 12v voltage, the screen will display the output voltage as 24v, and the switch button is pressed down. The communication protocol indicator light shows when the device is communicating, and it can display the communication status. Works with the following scanners: EasyDiag, EasyDiag 3.0, Golo Green Adition, M-DIAG, IDIAG, ICarScan, Diagun, GOLO, DBScar II GT106 Features: 1. The voltage is 12.5v, which is to simulate the real voltage after starting the vehicle. Similar products are 12v, but the normal car is about 12.5v after starting. 2. Let the diagnostic software better recognize the ignition voltage of the vehicle. Because some car models have requirements for the ignition voltage, and when the 12v decays a little to about 11v, some software with stricter requirements will alarm or stop the diagnosis. Note: Due to different production batches, there may be slight differences in products. Material: plastic colour: Black Package Contents: 2 x Heavy Duty Truck Adapter
