COMPONENT TESTING
In order to facilitate testing of the components, a Test Procedure has been created showing the contacts
to which the probes of the tester should be connected and the reading for each component.
To gain access to the electronic control board and the harness connectors, dismantle the door.
• Remove the harness connectors from the control board, connect the probes of the tester to the points
indicated in the table and compare the actual reading with the theoretical value.
• If preferred components that are easily accessible can be tested directly on the component. (Wiring
connections are excluded)
