Functional Test capability, availability, navigation and terminology is vehicle manufacturer dependent and will vary.
Functional tests may include:
| ● | Information Tests—read-only tests (i.e. selecting “VIN” to display the VIN of the vehicle). |
| ● | Toggle Tests—component state change tests (i.e. switching a solenoid, relay, or switch, between two operating states). |
| ● | Variable Control Tests—command variable value tests (i.e. varying spark timing in 1° increments or EGR valve duty cycle in 10% increments). |
| ● | Reset Tests—reset the adaptive, or learned, values that are stored in the vehicle electronic control module memory. |
| ● | Scripted Tests—preconfigured tests that are run when performing certain repairs (i.e. bleeding brakes with ABS). |
Follow all screen instructions while performing tests.
