STEP 7. Check the high-voltage circuit.
danger | - Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
- Wear the specified protection equipment during the check.

(1) Remove the service plug (Refer to ). (2) Apply a voltage of 12 volts to the CNT- terminal to turn on the charging contactor.
(3) Connect a high-voltage compatible multimeter between the main drive lithium-ion battery high-voltage terminal (REMCU) and the main drive lithium-ion battery service plug rear terminal.OK: Approximately 100 - 164 volts
(4) Apply a voltage of 12 volts to the CNTP terminal to turn on the charging contactor.
(5) Connect a high-voltage compatible multimeter between the main drive lithium-ion battery high-voltage terminal (REMCU) and the main drive lithium-ion battery service plug front terminal.OK: Approximately 100 - 164 volts
(6) Apply a voltage of 12 volts to the CNT+ terminal to turn on the charging contactor.
(7) Connect a high-voltage compatible multimeter between the main drive lithium-ion battery high-voltage terminal (REMCU) and the main drive lithium-ion battery service plug front terminal.OK: Approximately 100 - 164 volts
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope with Intermittent Malfunction ). Reconnect the high-voltage wiring harness or replace the main drive lithium-ion battery (Refer to GROUP 54Dc - Main Drive Lithium-ion Battery Removal and Installation ). Then go to Step 8.
