Front wheel alignment adjustment
  1. Perform "Reset Memory".
  2. Perform acceleration sensor zero point calibration and store system information memorization.
  • VSC is disabled or malfunctions
  • DTCs are output
  • Slip indicator light illuminates
  • ABS warning light illuminates

for HV Model:

  • When removing or installing the front 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.
