Power Trunk Lid System (for HV Model)

NOTICE:

for HV Model:
  • After the power switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal. (for Audio and Visual System)
  • After the power switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal. (for Navigation System)

CAUTION / NOTICE / HINT

for HV Model:

  • When removing or installing the rear disc brake caliper assembly, pushing back the disc brake piston may cause a large clearance between the brake pads and brake disc. When the brake pedal is depressed with a large clearance between the brake pads and the brake disc, DTC C1214 related to abnormal brake fluid pressure may be stored. Make sure to clear any DTCs after performing this procedure.
  • While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch turns on. Therefore, when servicing the brake system components, do not operate the brake pedal or open/close the doors while the auxiliary battery is connected.

HINT:

  • Use the same procedure for the RH side and LH side.
  • The following procedure is for the LH side.

PROCEDURE

1. PRECAUTION (for HV Model)

NOTICE:

After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

7. INSPECT REAR AXLE HUB BEARING LOOSENESS

(a) Using a dial indicator with magnetic base, check for looseness near the center of the rear axle hub.

Maximum Looseness:

0.05 mm (0.00196 in.)

NOTICE:

  • Ensure that the dial indicator is set perpendicular to the measurement surface.
  • Keep the magnet of the dial indicator away from the rear axle hub and bearing assembly.

HINT:

If the looseness exceeds the maximum, replace the rear axle hub and bearing assembly.

8. INSPECT REAR AXLE HUB RUNOUT

(a) Using a dial indicator with magnetic base, check for runout on the surface of the rear axle hub outside the rear axle hub bolts.

Maximum Runout:

0.05 mm (0.00196 in.)

NOTICE:

  • Ensure that the dial indicator is set perpendicular to the measurement surface.
  • Make sure to install the tip of the dial indicator towards the outside of the rear axle hub bolts.
  • Keep the magnet of the dial indicator away from the rear axle hub and bearing assembly.

HINT:

If the runout exceeds the maximum, replace the rear axle hub and bearing assembly.
