5. INSTALL REAR TRACTION MOTOR CABLE

CAUTION:

Be sure to wear insulated gloves.

NOTICE:

  • Protect the rear traction motor cable with a plastic bag or other protective material until immediately before reconnection.
  • Do not allow foreign matter or water to enter the rear traction motor cable terminal or installation area.
  • Do not touch the rubber seal and terminals of the rear traction motor cable.

HINT:

Unnecessary to remove the rear traction motor cable unless inspection or replacement.

(a) Clean the area around the terminal of the rear traction motor cable, and then blow air on the terminal to remove dust and other foreign matter.

NOTICE:

  • Blowing air without cleaning first may cause dust and other foreign matter to enter the terminal.
  • Dust or other foreign matter entering the terminal when installing the rear traction motor cable may cause a short or electrical leakage.

(b) Using an insulated tool, install the rear traction motor cable to the rear traction motor with transaxle assembly with the 3 bolts.

Torque:

10 N·m {102 kgf·cm, 7 ft·lbf}

(c) Engage the 2 claws to install a new motor cable terminal cap to the rear traction motor with transaxle assembly.

NOTICE:

  • Do not pinch the O-ring.
  • Check that the motor cable terminal cap is securely installed.

(d) Slide the cover on the top side of the rear traction motor cable.
