16. CHECK HYBRID BATTERY JUNCTION BLOCK 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 manual because this may cause a malfunction.

(b) Disconnect the high voltage cable connector of the HV battery f2 and h2 from the hybrid battery junction block assembly.





(c) 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:





NG -- REPLACE HYBRID BATTERY JUNCTION BLOCK ASSEMBLY Components

OK -- REPLACE HV BATTERY Components

17. CHECK MOTOR CABLE

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 motor cable from the hybrid vehicle transaxle assembly Components.

(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:
