P0AA6-614 - Hybrid Battery Voltage System Isolation Fault (Continued)

11. CHECK HYBRID VEHICLE TRANSAXLE ASSEMBLY (GENERATOR CABLE)

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 manual because this may cause a malfunction.

(b) Using a megohmmeter set to 500 V, measure the resistance according to the value(s) in the table below.

NOTICE:
Be sure to set the megohmmeter to 500 V when performing this test. Using a setting higher than 500 V can result in damage to the component being inspected.

Standard Resistance:

12. CHECK HIGH VOLTAGE DIRECT CURRENT AREA

CAUTION:
Be sure to wear insulated gloves.

(a) Turn the power switch off.

(b) 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 manual because this may cause a malfunction.

(c) Disconnect the frame wire S1 from the inverter with converter assembly.

HINT
Make sure that no foreign objects have entered or contaminated the connector of the frame wire S1.

(d) Using a megohmmeter set to 500 V, measure the resistance according to the value(s) in the table below.

NOTICE:
Be sure to set the megohmmeter to 500 V when performing this test. Using a setting higher than 500 V can result in damage to the component being inspected.

Standard Resistance:
