FRONT AXLE HUB ON-VEHICLE INSPECTION

Note


  • When the brake pedal is first depressed after replacing the brake pads or pushing back the disc brake piston, DTC C1214 may be output. As there is no malfunction, clear the DTC.

  • While the 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 brake system components, do not operate the brake pedal or open/close the doors while the battery is connected.
