DIAGNOSIS AND TESTING
INSPECTION, VERIFICATION AND ADDITIONAL WARNINGS FOR ELECTRIC VEHICLES
WARNINGS:
- A risk assessment must be performed before any work is undertaken.
Failure to comply with this
instruction may result in personal injury or death.
- All electric vehicle work must be performed by a suitably qualified
person. Failure to comply with this
instruction may result in personal injury or death.
- Appropriate Personal Protection Equipment (PPE) must be worn when
working on or near an electric
vehicle high voltage system. Failure to comply with this instruction may
result in personal injury or death.
- The hybrid/EV battery pack casing must not be disassembled due to the
risk of exposure to hazardous
voltage. Failure to comply with this instruction may result in personal
injury or death.
- The electric power inverter converter casing must not be disassembled
due to the risk of exposure to
hazardous voltage. Failure to comply with this instruction may result in
personal injury or death.
- If the hybrid/EV battery pack is damaged or overcharged, there is a
risk of exposure to hazardous voltage
and/or highly corrosive electrolyte mist. If liquid or vapor is observed
leaking from the hybrid/EV battery
pack, take the following action:
- Evacuate the area.
- Notify manager.
- Do not breathe smoke/vapor.
- Contain spillage using spill kit.
- Wash any spillage off body and clothing (remove contaminated
clothing).
- If the electric vehicle warning indicator is illuminated, the battery
energy control module cannot isolate the
high voltage cables. Be aware that live working will be necessary to rectify
the fault. Failure to comply with
this instruction may result in personal injury or death.
- Be aware that a motor generator can generate a voltage if the wheels
are rotated, even if the electric
vehicle system has been made safe. Failure to comply with this instruction
may result in personal injury or
death.
CAUTION:
Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution
of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the
vehicle being tested and/or the
donor vehicle.
NOTES:
- If the control module or a component is at fault and the vehicle
remains under manufacturer warranty,
refer to the Warranty Policy and Procedures manual, or determine if any
prior approval program is in
operation, prior to the installation of a new module/component.
- When performing voltage or resistance tests, always use a digital
multimeter that has the resolution ability
to view 3 decimal places. For example, on the 2 volts range can measure 1mV
or 2 K Ohm range can
measure 1 Ohm. When testing resistance always take the resistance of the
digital multimeter leads into
account.
- Check and rectify basic faults before beginning diagnostic routines
involving pinpoint tests.
- Verify the customer concern
- Visually inspect for obvious signs of mechanical or electrical damage
Visual Inspection
- If an obvious cause for an observed or reported concern is found,
correct the cause (if possible) before
proceeding to the next step
- If the cause is not visually evident, verify the symptom and refer to
the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index
- Check the JLR claims submission system for open campaigns. Refer to the
corresponding bulletins and SSMs
which may be valid for the specific customer complaint and complete the
recommendations as required
