Retirar
- Open all four doors.
- Lower all four windows.
- Move LH front seat forward.
- Move RH front seat forward.
- Remove the 2nd row lower seat cushion. See Cojín del asiento - Parte inferior - 2.ª fila (Desinstalación y sustitución).
- Remove the rear underhood apron. See Faldón del vano del motor - Parte trasera (Desinstalación y sustitución).
- Remove the HEPA filter assembly. See Conjunto - Filtro - HEPA (Desinstalación e instalación).
-
Power off vehicle from center
display.
NotaVia Controls > Safety > Power Off, Select Power Off button at warning dialogue box.
-
Disconnect LV battery connector and
First Responder Loop.
Nota2x connectors, Lift up and release green locking tab, Pull black connector lock outwards to release connection, Release red lock tab on FRL, Allow 2 minutes for all electrical circuits to fully discharge.
-
Verify operation of multimeter.
NotaSet multimeter to DC voltage, Confirm multimeter is properly measuring voltage by testing LV battery, Touch lightly and do not damage terminals.
-
Raise and support vehicle.
NotaEnsure vehicle is not charging, Note the MYSP lifting points are more narrow than the MY.
-
Raise vehicle fully and lower lift
onto locks.
NotaSet vehicle to comfortable working height, Make sure there's an audible click of the locks on both sides before lowering, otherwise vehicle may tilt to the side.
-
Remove push clips at left and right
wheel house liner to mid aero shield.
Nota2x clips.
-
Remove mid aero shield.
Nota11x bolts, 10mm, 5 Nm, Fasteners may vary, MYSP will have one less bolt and an extra clip.
- Remove all items from pockets and ensure not wearing metal items.
-
Inspect HV insulating gloves.
NotaCheck gloves for damage prior to use, Refer to service document TN-15-92-003 R1, for information on inspecting HV gloves.
-
Put on HV insulating gloves and
leather over gloves.
NotaMake sure to wear Electrical Protective Gloves any time Hioki tester is used.
-
Install amp clamp to RDU HV
harness.
NotaVerify meter is zeroed out before performing measurement, Measure single cable. Verify ammeter is installed in correct direction. If current > 0.5A do not proceed with disconnecting HV connector. In this case, start vehicle electrical isolation again to make sure that all was properly shut down. Escalate for assistance as requiredIf current < 0.5A, Ok to disconnect and check voltage at HV plug on the battery side.
-
Release RDU HV harness from HV
battery.
Nota1x connector, Release locking tab and rotate the release lever up to disengage the connector, Do not force the release lever up, Ensure the alignment tabs on the RDU header are not damaged.
-
Verify no high voltage at RDU HV
header.
NotaMake sure to wear PPE (HV gloves, safety glasses) when working on high voltage component, Measure B+ to Ground, B- to Ground, B+ to B-, If voltage is greater than 10V, Pack contactors are not open or welded, Stop work and reach out to Service Engineering.
-
Lower vehicle until tires are touching
the ground.
NotaRaise lift off locks, then hold lock release lever to keep locks free while vehicle is lowered.
-
Cut away insulation covering pyro
cover.
NotaIf insulation is present then cut away.
-
Remove pyro disconnect cover.
Nota2x bolts, E10, 10 Nm.
-
Remove the pyro disconnect
insulators.
Nota2x insulators, Make sure to wear proper PPE from this step onward until the ancillary bay cover has been secured.
-
Remove bolts securing pyro disconnect
to ancillary bay.
Nota2x bolts, 5 Nm + 60 degrees, Discard after removal.
-
Remove pyro disconnect from
ancillary bay.
Nota1x connector from the bottom, Lift pyro disconnect straight up and out of the ancillary bay.
- Install pyro disconnect dummy cover.
Instalar
- Record the replacement pyrotechnic battery disconnect serial number and part number for later entry into SCA.
-
Perform a zero adjust of the Hioki
resistance meter in preparation to measure resistances later in this procedure. See
Medidor de resistencia (Ajuste a cero).
AvisoDurante el resto del procedimiento se deben utilizar guantes aislantes para alta tensión y guantes protectores de cuero. No se quite los guantes ni las protecciones hasta que se le indique.
- Remove pyro disconnect dummy cover.
- Use an IPA wipe to clean the HV mating surfaces of the shunt, busbar, and the pyrotechnic battery disconnect, and allow at least 1 minute to fully dry.
- Set the multimeter to the "LoZ" (low impedance) mode.
-
Measure the voltage between the busbar
(top) and shunt (bottom) for at least 10 seconds, so as to balance the voltage across
the pyrotechnic battery disconnect mount points.
NotaThe voltage displayed on the multimeter is not as important as balancing the mount points.
-
Position the pyrotechnic battery
disconnect into the ancillary bay, align the pins of the connector with the disconnect, and
then press the disconnect straight down onto the busbars.
NotaIf the pyrotechnic battery disconnect immediately triggers, perform these alternative steps, otherwise go to step 8:
-
Install bolts securing pyro disconnect to ancillary bay.
Nota2x patch bolts, 13mm, 5 Nm +60 degrees, Install new fasteners.
-
Measure resistance from pyro disconnect to busbar.
Nota1x HV joint, 0.060 mΩ (60 μΩ) or less, Verify Hioki tester is properly zeroed before usage, If the impedance is higher, escalate a Toolbox session, as appropriate.
-
Measure resistance from the pyro disconnect to shunt.
Nota1x HV joint, 0.045 mΩ (45 μΩ) or less, Verify Hioki tester is properly zeroed before usage, If the impedance is higher, escalate a Toolbox session, as appropriate.
-
Install the pyro disconnect insulators.
Nota2x insulators.
-
Install pyro disconnect cover.
Nota2x bolts, E10, 10 Nm.
-
Raise vehicle fully and lower lift onto locks.
NotaSet vehicle to comfortable working height, Make sure there's an audible click of the locks on both sides before lowering, otherwise vehicle may tilt to the side.
-
Secure RDU HV harness onto HV battery.
Nota1x connector, Verify lever is in the upright and open position, Carefully seat connector and allow lever to engage, Fully secure lever and verify red tab is locked, Do not damage any pins.
- Remove HV insulating gloves.
-
Apply Loctite 222 onto mid aero shield bolts and install mid aero shield.
Nota11x bolts, 10mm, 5 Nm, Fasteners may vary, Model Y Structural Pack will one less bolt and one extra clip.
-
Install push clips at left and right wheel house liner to mid aero shield.
Nota2x clips.
-
Lower vehicle fully.
NotaRaise lift off locks, then hold lock release lever to keep locks free while vehicle is lowered.
-
Remove vehicle from lift.
NotaLower rack arms fully and remove from under vehicle.
- Install the 2nd row lower seat cushion. See Cojín del asiento - Parte inferior - 2.ª fila (Desinstalación y sustitución).
-
Connect first responder loop and LV battery.
Nota2x connectors, Secure FRL first, Seat LV battery connection and push black connector lock inwards to secure, Engage green locking tab when fully seated.
- Install the HEPA filter assembly. See Conjunto - Filtro - HEPA (Desinstalación e instalación).
