Inspection And Verification
WARNING:
- 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 Protective 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/Electric Vehicle (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 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.
- Before carrying out a road test, make sure the vehicle is safe to do so. Failure to follow this instruction may result in personal injury
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 checked and/or the donor vehicle
NOTE:
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
