How to Disable Electrical System

Turning off power to the high voltage circuit

Follow this procedure before you work on or near any high voltage components. Follow it exactly, otherwise, you may injure yourself or damage equipment.

1. Turn the ignition switch OFF.
2. Remove the cargo floor mat.




3. Remove the battery module cover (A) from the IPU lid, and remove the locking cover (B) from the battery module switch.




4. Turn the switch (A) OFF, then turn the locking cover around (B) and put it back on the switch.
5. Wait for at least five minutes to let the condensers discharge.
6. Remove the IPU lid.




7. Measure voltage at the junction board terminals. There should be 30 V or less. If voltage is present, there is a problem in the circuit; do the DTC troubleshooting first.
