SPECIAL TOOLS
Kit, Inverter Leak Test Adapter, M3 (1450875-00-A)
Perform the vehicle electrical isolation procedure. See
Vehicle Electrical Isolation Procedure.
Remove the mid aero shield panel. See Panel - Aero
Shield - Mid (Remove and Replace).
Disconnect the signal harness from the inverter signal
connector, and then install the leak test adapter plug into
the connector.
Release the lock on the rear drive unit HV battery cable
connector.
Swing the release handle for the rear drive unit HV
battery cable connector, and then disconnect the rear drive
unit HV battery cable.
Install the leak test adapter to the connector.
Connect the pack enclosure leak tester to the leak test
adapter on the HV electrical connector.
Close both valves on the pack enclosure leak tester, and
then connect a compressed air supply line.
Fully close the regulator, and then open the inlet
valve.
Set the regulator to 1 psi.
Open the outlet valve, and allow at least 45 seconds for
the pressure to stabilize to 1 psi.
Close the inlet valve, record the starting pressure
displayed, and then start a 60-second timer.
After 60 seconds record the ending pressure displayed.
Subtract the ending pressure from the starting pressure,
and if:
The difference is greater than 0.04 psi, check the
hose, adapter, and plug fittings, close the outlet valve
and open the inlet valve, check the regulator pressure,
and then retest from step 11. If the difference is still
greater than 0.04 psi, escalate a Toolbox session.
The difference is 0.04 psi or less, continue the
procedure.
Disconnect the air supply from the pack enclosure leak
tester.
Open the inlet valve, and then disconnect the pack
enclosure leak tester from the leak test adapter on the HV
electrical connector.
Remove the leak test adapter from the rear drive unit HV
electrical connector.
Fully raise the handle on the rear drive unit HV
electrical harness.
Attach the HV connector lever lock onto the back of the
HV electrical harness.
Firmly connect the HV electrical harness to the inverter
connector.
Caution:
Make sure that the harness fits the connector
squarely and tightly.
While pressing the harness to the connector, remove the
HV connector lever lock.
While pressing the harness to the connector, fully lower
the handle.
Slide the release to lock the HV electrical harness.
Remove the leak test adapter plug from the inverter
signal connector, and then connect the signal harness to the
connector.
Install the mid aero shield panel. See Panel - Aero
Shield - Mid (Remove and Replace).
Connect 12V power. See 12V Power (Disconnect and
Connect).
