Integrated Electric Oil Pump (IEP): Notes
Orange is the warning color used to identify high voltage parts. These warning labels are attached to the high-voltage battery pack.
When performing any repairs that involve contact with high voltage components or systems, the technician performing repairs on the vehicle must verify that the system remains powered down during high voltage repairs.
- This must be done by removing the service disconnect or high voltage disabling device or high voltage disabling device.
- The high voltage power down procedure must also be performed to ensure that the vehicle is properly powered down.
- The technician must know the whereabouts of the service disconnect or high voltage disabling device or high voltage disabling device throughout the repair.
- The technician must ensure that no one reconnects the service disconnect or high voltage disabling device or high voltage disabling device while service is being performed.
- The technician must recheck that the service disconnect or high voltage disabling device or high voltage disabling device has not been reinstalled in cases where the vehicle was unattended.
Failure to comply with all these warnings may result in personal injury including burn, shock, or fatal injury.
Before performing any diagnostic or service procedure, you must thoroughly read and follow all applicable high voltage safety procedures. You must perform the high voltage power down procedures.
Loss of Isolation (LOI) must be performed before high voltage power up in cases where service has been performed on a high-voltage component or when diagnosing a LOI condition.
Be sure to use the proper safety equipment when working on any high voltage system or component. Failure to do so may result in serious or fatal injury.
Wait a minimum of two minutes after performing the high voltage battery disconnect procedure before attempting to access the high voltage system. Failure to do so may result in serious or fatal injury.
Dirt Intrusion Caution
To prevent dirt which might damage or impair the seal from entering, fit the protective caps included in the specific equipment onto the disconnected electrical connections.
Water Intrusion Caution
Do not allow liquids to come into contact with the high voltage component electric connections, since they would create a conductive path and thus cause loss of insulation. These substances would be difficult to remove and the contaminated high voltage component would have to be replaced.
Fragile Wiring Caution
The high voltage wiring is a very fragile, delicate component, so it must be handled with the greatest care. The pre-formed elbows must not be straightened.
