Inspection Procedure

WARNING:

Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

NOTE:

DTC P0A79-716 is stored after any of DTCs P0A79-136, 692, 693, 694, 695, 696, 712, 812, 813 and 814 are stored. After troubleshooting and repairing DTC P0A79-716, be sure to troubleshoot all the other DTCs.
Depending on the conditions in which the vehicle is being operated when a short circuit occurs in the inverter with converter assembly, the No. 3 frame wire (rear motor cable), extension wire assembly, or rear traction motor with transaxle assembly may be affected. As this DTC is stored if a short circuit occurs in the inverter with converter assembly, perform a road test to check the No. 3 frame wire (rear motor cable), extension wire assembly, and rear traction motor with transaxle assembly. If problems are found, replace the malfunctioning parts.
After completing the repair, including repairing of previously output DTCs, drive the vehicle at a speed of approximately 25 mph (40 km/h) for 1 minute and check that DTC P0A91-705 (Drive Motor "B" Performance) is not output. If DTC P0A91-705 (Drive Motor "B" Performance) is output, replace the rear traction motor with transaxle assembly.

HINT:

Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
