4.4.5 Order of Treatment

To minimize disruptive effects of repeatedly breaking and making connections perform the following order
of treatment using the Stage 1 and Stage 2 processes for each plug and socket in turn:
1. Treat sensor connector and cable (ensure battery is disconnected at this point).
2. Treat battery connector and cable (ensure sensor is disconnected at this point).
3. Treat all other peripheral connections and cables.
4.4.6 Stage 1 – Oxide Removal and Cleaning
To remove existing oxide and clean the pins:
1. Apply a short burst (around 0.5 second duration) of DeoxIT DN5 spray to the metal surfaces of the
connectors and to the gold connector pins.
Fig. 4.3 Cleaning the Gold Connector Pins
2. Connect a corresponding male / female connector to the connector under test 5 times.
3. Wait 10 seconds.
4. Reapply one short burst (around 0.5 s duration) of DeoxIT DN5 spray to the metal surfaces.
5. Allow any residue to run out of connector.
6. Wait 30 seconds for the application to dry.
Note. The surfaces may not appear completely dry after this time as a protective layer is left
behind when the carrier evaporates.
