measuring points
The image below shows the measuring points on the secondary diodes.
The secondary diodes can be measured in the de-energised state with a multimeter in
diode test mode.
A voltage of approx. 0.15 V must be measured in the conducting direction of the diode
(1). Other measuring results indicate a defect in the diode, meaning it needs to be
replaced.

A temperature-dependent resistance as per the table below must be measured between
pins 1 and 2 of the X2 connector.
