This article provides a general overview of 24V diagnostics and links to more detailed documentation.
Jifeline supports remote diagnostics for 24V trucks. With 24V support enabled, partners can handle truck diagnostic tickets directly from their existing dashboard, using the same workflow as for 12V vehicles.
12V vs 24V
A 12V Local is designed for passenger vehicles with a 12-volt electrical system. A 24V Local is designed for trucks using a 24-volt electrical system.
Some diagnostic tools require a full 24V signal on the OBD port to function correctly. In those cases, a 24V Local is required.
