How to Disable Electrical System

Turning off power to the high voltage circuit
The following procedure should be performed prior to working on or near any high voltage components. Follow the procedure exactly. Otherwise, you may be injured 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).





4. Turn the battery module switch (A) OFF, then install the locking cover (B).
5. Wait for at least 5 minutes to allow the PDU capacitor (condenser) to discharge.





6. Remove the right side trunk shelf support (A).





7. Remove the mid-frame cover clips and the IPU lid (A).





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