26. CHECK HYBRID VEHICLE TRANSAXLE ASSEMBLY (GENERATOR CABLE CONNECTION CONDITION)
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) Remove the inverter with converter assembly.
(c) Check that the bolts for the generator cable are tightened to the specified torque, the generator cable is connected securely, and there are no contact problems.
Specified Condition:
Bolt A
T=20 N*m {204 kgf*cm, 15 ft.*lbf}
Bolt B
T=10 N*m {102 kgf*cm, 7 ft.*lbf}
NOTICE:
- Make sure that the tightening torque of the bolt A is between 16 and 24 N*m (163 and 245 kgf*cm, 12 and 18 ft.*lbf).
- Make sure that the tightening torque of the bolt B is between 8 and 12 N*m (82 and 122 kgf*cm, 71 and 106 in.*lbf).
(d) Disconnect the generator cable from the hybrid transaxle assembly.
(e) Check for arc marks at the bolts for the generator cable.
Result:
(f) Connect the generator cable to the hybrid transaxle assembly.
(g) Install the inverter with converter assembly.
B -- REPLACE MALFUNCTIONING PARTS
C -- CONNECT SECURELY
A -- Continue to next step.
27. CHECK 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) Remove the generator cable.
(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:

NOTICE:
Wrap the terminal of the three-phase AC cable with insulating tape to prevent them from coming into contact with body ground
(d) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
(e) Install the generator cable.
NG -- REPLACE GENERATOR CABLE Components
OK -- REPLACE HYBRID VEHICLE TRANSAXLE ASSEMBLY Components
