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 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:
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
- Verify the customer concern
- Confirm which, if any, warning indicators and/or messages were displayed on the instrument cluster. For a list of messages: Refer to: MESSAGE CENTER .
- Visually inspect for obvious electrical faults
- With the ignition on, check the operation of the audio output from the instrument cluster integrated speakers by operating the turn signal indicators (left and right) and verifying that audible feedback is presentVISUAL INSPECTION
ELECTRICAL - Battery
- Fuses
- Passenger and battery junction boxes
- Megafuses
- Wiring harness
- Damaged, loose or corroded connectors
- CAN circuits
- Instrument cluster
- Gateway module
- Engine control module
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
- 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.
- Use the approved diagnostic system or a scan tool to retrieve any Diagnostic Trouble Code(s) (DTC)s before moving onto the DTC
index
- Make sure that all DTC s are cleared following rectification
