08–00 Safety Precautions
Safety Precautions in this section apply to all
procedures within this group.
DANGER
Electric vehicles are equipped with a high-voltage
system. Do not attempt any type of electrical work
on the vehicle unless you have completed HV3
Daimler Safety Training. Failure to do so could
cause severe personal injury or death.
When working on the vehicle, shut down the
engine or motor, set the parking brake, and chock
the tires. Before working on the vehicles, always
place jack stands under the frame rails to ensure
the vehicle cannot drop. For an electric vehicle,
decommission the vehicle and verify the high-
voltage system is shut down. Failure to follow
these steps could result in serious personal injury
or death.
08–01 High Voltage Electrical
Component Inspection
DANGER
Electric vehicles are equipped with a high-voltage
system. Do not attempt any type of electrical work
on the vehicle unless you have completed HV3
Daimler Safety Training. Failure to do so could
cause severe personal injury or death.
1. Park the vehicle on a level surface, shut down
the vehicle and set the parking brake. Chock the
tires.
2. Inspect the condition of the electrical component.
Check for signs of excess dirt and debris build
up on or around components. If exterior cleaning
is needed for a thorough inspection, clean
exterior debris from the component using a dry
method such as a vacuum cleaner or an
electrical contact cleaner such as CRC QD®
Electronic Cleaner.
3. Check all mounting points for loose, broken, or
missing parts. Components must be securely
mounted. All loose, broken, or missing parts
must be repaired to maintain proper component
function.
4. Inspect the component protective cover for
proper fit and function. Inspect the cover for
cracks, broken mounting, missing sealing
surfaces, and warped or bulged surfaces. The
cover must prevent moisture and debris from
entering the components protected area.
Missing, leaking, or damaged covers will result in
moisture and debris entering the component and
will result in component failure. When it is
determined that a cover has not properly
prevented moisture and debris from entering the
component, the entire component must be
replaced.
5. Inspect the component exterior for signs of
thermal distortion, warping, bulging, discoloration,
amperage related heating, color variance or
shading across the component which could be a
sign of internal failure requiring replacement of
the component. The root source causing
conditions of high heat, excess amperage, and/or
circuit overload component failures must be
diagnosed and repaired prior to replacing the
component.
6. Inspect the component housing sub-assembly
clips and fasteners for correct fit and location,
and that the component sub-assembly housing
seams are tight and secure. Missing, leaking, or
damaged component housings must be replaced.
7. Inspect component harnesses for secured
routing that prevents excess harness movement
and prevents the harness from pulling too tight
on the connector. Inspect harnesses for signs of
rubbing or chafing that could result in wire circuit
damage.
IMPORTANT: Do not attempt to repair high
voltage cables. If the insulation on the cable
appears damaged, the harness must be
replaced.
