Test Steps
Notes: After each measurement series (block under "Notes"), always recreate the basic conditions unless the next measurement series specified the same conditions.
For measurements in the engine compartment, note that the radiator fan motors can start operating.
Route measurement lines in the engine compartment in such a way that they cannot get caught in the fans.
All test steps should be performed with the engine cold, so that all switches (sensors) are in their output positions.
Always measure to body ground (not battery ground).
