Note: This procedure describes how to remove and install
the 1st generation slave charger. If the vehicle is equipped with a
2nd generation slave charger, refer to procedure 44102102 (refer to
procedure).
Warning: Only technicians who have been trained in High
Voltage Awareness are permitted to perform this procedure. Proper
personal protective equipment (PPE) and insulating HV gloves with a
minimum rating of class 00 (500V) must be worn any time a high
voltage cable is handled. Refer to Tech Note TN-15-92-003, "High
Voltage Awareness Care Points" for additional safety information.
Warning: To avoid personal injury, eye protection must be
worn while using compressed air.
Removal
Note: The slave charger is optional equipment. This
procedure describes replacement of a failed slave charger. To
install a slave charger in a vehicle that is only equipped with
1 charger, refer to Service Bulletin SB-12-44-005.
- Remove the HV junction box (refer to procedure).
- Disconnect the low voltage harness connector from the slave
charger.
- Remove the nuts (x4) that secure the charger to the body (torque
6.5 Nm).
- Remove the bolt that secures the ground strap to the charger
case (torque 6.5 Nm).
- Position the ground strap aside.
- Clamp both coolant hoses near the charger to minimize coolant
loss.
- Remove the coolant plug from the inboard side of the replacement
charger and have it ready before performing the next step.
-
Note: Place suitable absorbent material around the
affected area to absorb any possible fluid spillage.
Tilt the inboard side of the charger upwards. Remove the coolant
hose from the charger and immediately insert the coolant plug into
the charger to stop coolant from spilling out.
- Repeat steps 7-8 on the outboard coolant hose.
- Remove the slave charger.
- If the charger is being shipped or stored, allow the coolant to
drain from the charger, then use compressed air lightly to blow out
any remaining coolant.
Caution: Do not exceed 25 PSI when using compressed
air to blow out any remaining coolant.
Installation
- Installation procedure is the reverse of removal, except
for the following:
- After the HV junction box and slave charger are reinstalled,
restore power to the vehicle by reversing the Electrical Isolation
procedure.
Note: Do not reinstall the rear seat cushion yet.
- Connect a laptop with Toolbox to the Ethernet port and
powertrain CAN bus.
- Use the Toolbox "Charger Config" panel to configure the master
charger:
- Use the Toolbox "Resets" panel to reset the Gateway.
- Refill and bleed the cooling system (refer to procedure).
Note: While the coolant air purge routine is
running, check the charger coolant hose connections to make
sure there is no leakage.
- Perform a full firmware update.
- If possible, charge the vehicle at above 40 A for several
minutes and verify that there are no alerts.
