2-5 High Voltage Safety System
The
high voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high voltage electricity. • A high voltage fuse provides short circuit protection inside the high voltage battery.
• The high voltage safety system is insulated from the metal chassis.
• Positive and negative high voltage power cables are connected to the high voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high voltage battery. However, it can take up to
ten (10) minutes for the high voltage capacitor to fully discharge. • The high voltage system and high voltage capacitor may remain powered for up to 10
minutes
after the vehicle is shut off.
• The high voltage battery retains high voltage at all times.
• A ground fault monitor continuously monitors for high voltage leakage to the metal chassis while the vehicle is running. If a malfunction is detected, the HPCM (hybrid powertrain control module) will
illuminate the hybrid system warning lamp in the instrument cluster.
•

The high voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow
in a frontal collision that is sufficient enough to activate the supplemental restraint system (SRS) . AAYIA0001GB

3. Preparation for Dismantling
• Failure to properly shut down the high voltage electrical system before the
Dismantling Procedures are performed will result in serious injury or death from
electrical shock. To prevent serious injury or death, DO NOT touch high voltage
harnesses or components without always wearing appropriate PPE.
• If it is necessary to touch any of the high voltage harnesses or components you must
always
wear appropriate PPE to avoid electrical shock. Shut down the high voltage
system by following the steps outlined in 3-3.1 High Voltage System Shut-Down Proce-
dure. Wait at least ten (10) minutes for complete discharge of the high voltage capacitor
after

the high voltage system has been shut down. • NEVER assume the M35h HYBRID is shut OFF simply because it is quiet.
•

If it becomes necessary for the dismantler to leave the vehicle, place a “DANGER” sign
(for example, refer to 5. Storing the Vehicle) on the vehicle to alert other people that the
vehicle

contains a high voltage battery.
• If the READY indicator is ON the high voltage system is active.
•

If possible, be sure to check the READY indicator on the instrument cluster and
verify

that the READY indicator is OFF and the high voltage system is stopped.

• The vehicle contains parts that contain powerful magnets. If a person who is wearing
a
pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to check the READY indicator (1) in the instrument cluster, and verify that the READY indicator is off and the high voltage system is stopped.
• After the high voltage system is shut down, please wait for ten (10) minutes for complete discharge of the high voltage capacitor. While waiting, do not operate any vehicle
functions.
NOTE:
The high voltage full discharge takes ten (10) minutes, but after five (5) minutes the voltage
has dropped below 60V.
• Remove the 12V battery negative (-) terminal and wait for three (3) minutes to discharge the air bag capacitor. Even though the 12V battery negative (-) is disconnected, the
Supplemental Restraint System (SRS) air bag maintains voltage for three (3) minutes.
There is a possibility of sudden SRS air bag inflation due to harness short circuit or
damage and it may cause serious injuries.
• The 12V system will remain active even after the 12V battery negative (-) terminal is removed while the high voltage system is active. This is because the DC/DC converter will
not shut down and power will be supplied to the 12V system and high voltage system
continuously.
Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, open the trunk, etc. as required. Once the 12V battery is disconnected,
power controls will not operate.
Powering Down the High Voltage System
The high voltage system can be shut down with any 1 of the following procedures: • Turn OFF the power switch and disconnect the 12V battery. Refer to Primary Procedure.
•

Remove the fuse for the high voltage control system and disconnect the 12V battery. Refer to Alter-
nate

4. Jump Starting
T
o start the hybrid system with a booster battery, the instructions and precautions below must be followed. If done incorrectly, jump starting can lead to a 12V battery explosion, resulting in severe
personal

injury or death. It could also damage your vehicle.
Jump starting provides power to the 12V system to allow the electrical systems to operate. The electrical
systems must be operating to allow the Li-ion battery to be charged. Jump starting does not charge the
Li-ion battery.
Discharged 12V battery may cause the following issues: • The instrument cluster cannot be displayed while the ignition switch is turned ON. (The hybridsystem cannot start.)
• Headlamps, horn, etc. are weak. • To avoid electrical shock, the high voltage Li-ion battery CANNOT be jump started.
•

Explosive hydrogen gas is always present in the vicinity of the 12V battery. Keep all
sparks and flames away from the 12V battery.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution that can cause severe burns. If
the fluid comes into contact with anything, immediately flush the contacted area with
water.
• The booster battery must be rated at 12 volts. Use of an improperly rated battery can damage the vehicle.
• Whenever working on or near a 12V battery, always wear suitable eye protectors (for example, goggles or industrial safety spectacles) and remove rings, metal bands, or any
other jewelry. Do not lean over the 12V battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• M35h HYBRID is equipped with an automatic cooling fan. It could come on at any time. Keep hands and other objects away from it.
• Always follow the jump starting instructions below. Failure to do so could result in damage to the DC/DC converter and cause personal injury.
