Inspection, Verification And Additional Warnings For Electric Vehicles

WARNING: This page is about a different variant/trim than selected.
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 Protection Equipment (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 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.
  • DO NOT  remove the coolant expansion tank cap when the engine is hot. 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 tested and/or the donor vehicle.
NOTE:
  • If a 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 1 mV 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.
  1. Verify the customer concern
  2. Visually inspect for obvious signs of damage and system integrity

  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
  4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for Diagnostic Trouble Codes (Diagnostic Trouble Codes (DTC) s) and refer to the DTC  Index
  5. Check Jaguar Land Rover (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
