21. 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 ignition switch to ON (READY), unless instructed by the repair manual because this may cause a malfunction.
(b) Disconnect the z30 and z31 high voltage cable connectors of the HV battery 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 Removal
OK -- Continue to next step.
22. CHECK MAIN BATTERY CABLE
CAUTION:
Be sure to wear insulated gloves.
(a) Check that the service plug grip is not installed.
NOTICE:
