High Voltage Enabling

High Voltage Enabling

Danger: Ensure all High Voltage safety procedures are followed. Failure to follow the procedure exactly as written may result in serious injury or death.

Danger: Before working on any high voltage system, be sure to wear the following Personal Protection Equipment:

* Safety glasses with appropriate side shields when within 50 feet of the vehicle, either indoors or outdoors

* Certified and up-to-date Class "0" isolation gloves rated at 1000V with leather protectors

- Visually and functionally inspect the gloves before use.

- Wear the isolation gloves at all times when working with the high voltage battery assembly, whether the system is energized or not.

* Failure to follow the procedure exactly as written may result in serious injury or death.

Review the high voltage safety information prior to performing the High Voltage Enabling procedure. Refer to High Voltage Safety.

1. Ensure that the 12 volt battery is disconnected.

Important: Always tighten the high voltage fasteners to the specified torque. Insufficient or excessive torque will cause malfunctions or damage.

2. After finishing work on the high voltage systems and before reinstalling the high voltage manual disconnect lever, inspect for the following:

^ Verify high voltage system integrity and that all connectors are installed.
^ Verify that all tools or loose components have been removed.




3. Install the high voltage manual disconnect lever.
4. Connect the 12 volt battery.
5. Ignition ON, using a scan tool, clear all DTCs.
6. Ignition OFF wait 1 minute.
7. Ignition ON, verify with a scan tool no DTCs are set.

^ If DTCs are set go to appropriate DTC repair information.

8. Ignition OFF wait 5 minutes.
9. Ignition ON, Using a scan tool and verify that High voltage has enabled by reading the HPCM 300 V Circuit voltage parameter and that no other DTCs have set.
