INSPECTION PROCEDURE

CAUTION:
- 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 removing 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 Hybrid Control System: Precaution.
HINT
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

NOTICE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Service Precautions.

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - INVERTER WITH CONVERTER)

CAUTION:
Be sure to wear insulated gloves.

(a) Check that the service plug grip is not installed.

NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair information because this may cause a malfunction.

(b) Disconnect connector A62 from the inverter with converter assembly.

(c) Disconnect connector A20 from the power management control ECU.

(d) Turn the power switch on (IG).

(e) Measure the voltage according to the value(s) in the table below.





Standard Voltage:

NOTICE:
Turning the power switch on (IG) with the connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

(f) Turn the power switch off.

(g) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(h) Connect the inverter with converter assembly connector.

(i) Connect the power management control ECU connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. CHECK INVERTER WITH CONVERTER ASSEMBLY

CAUTION:
Be sure to wear insulated gloves.

(a) Check that the service plug grip is not installed.

NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair information because this may cause a malfunction.

(b) Disconnect connector A62 from the inverter with converter assembly.

(c) Measure the resistance according to the value(s) in the table below.





Standard Resistance:

(d) Connect the inverter with converter assembly connector.

NG -- REPLACE INVERTER WITH CONVERTER ASSEMBLY Components

OK -- REPLACE POWER MANAGEMENT CONTROL ECU Components
