VIA Service safety test
*Must complete test with 80% or better to pass
1) What is the function of the Manual Service Disconnect (MSD)?
a. Disconnects the traction motor from the manual transmission.
b. Removes the current flow between the high voltage battery and the charger.
c. Opens the HVIL circuit then the high voltage contacts internally to isolate the high voltage battery.
2) High voltage is normally considered to be over:
3) High voltage circuits should be identified primarily by:
a. Thickness of the wire
b. Wire covered either with orange conduit or orange in color
c. Tagged with a high voltage label or printed on the wire
4) It is safe to work on the high voltage system if the gauge shows depleted
a. Yes, but the gauge must show completely discharged
b. The high voltage disable procedure MUST always be performed
c. Dry leather gloves should be used in case there is residual voltage
5) If a high voltage battery shows damage or water intrusion
a. Put tape over the hole before charging
b. If water is present in the battery, dry completely prior to charging
c. Never charge or use a damaged or wet battery. Have it inspected or repaired first.
6) Safety glasses should be worn
a. Only if working with liquid lines
b. Always, and include side shields
c. Only if it is shop policy
7) The following components are high voltage
a. Cabin heater, traction motor and high voltage battery
b. Bi-directional charger, traction motor inverter and power steering pump
c. A/C compressor, 12V battery and DC/DC inverter
8) The serviceable parts in the high voltage battery are
b. Electrical distribution module
c. Fuse center
9) When working with the high voltage battery
a. Remove all metal objects such as rings and watches
b. Always perform the High Voltage Disable Procedure
c. Both a and b
10) A high voltage label is not on the following component:
a. Cabin heater
b. Power Steering pump
c. Bi-directional charger
