Inspection And Verification

WARNING:
  • A risk assessment must be performed before any work is undertaken. 
  • All hybrid electric vehicle work must be performed by a suitably qualified person. 
  • Appropriate Personal Protection Equipment (PPE) must be worn when working on or near a hybrid electric vehicle high voltage system. 
  • The hybrid electric vehicle battery pack casing must not be opened due to the risk of exposure to hazardous voltage, which may cause serious injury or death. 
  • The electric power inverter converter casing must not be disassembled due to the risk of exposure to hazardous voltage, which may cause serious injury or death. 
  • If the hybrid electric vehicle 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 electric vehicle 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 hybrid electric vehicle warning indicator is illuminated, the Battery Energy Control Module (BECM) cannot isolate the high voltage cables. Live working will be necessary to rectify the fault. 
  • The motor generator can generate a voltage if the wheels are rotated, even if the hybrid electric vehicle system has been made safe. 
CAUTION:
  • 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.
  • 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
  • Do not apply any grease based products to any parking assist system connector or pins
NOTE: Check 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.
  1. Verify the customer concern
