When checking the contacts of the control unit, insert the pointed probe of the tester into the connector from the wire side until it connects with the contact tip of the wire.
Attention. Piercing the wire insulation can result in poor or inconsistent contact. To check the connections, attach the tester probe to the connector contact (from the contact side). For "sockets" just touch the contact with the probe and do not push the probe into the connector contact.
