Note:

  • When the brake pedal is first depressed after replacing the brake pads or pushing back the disc brake piston, DTC C1341, C1342, C1343 and/or C1344 may be stored. As there is no malfunction, clear the DTCs.

  • 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 is turned on. Therefore, when servicing, do not depress the brake pedal or open/close the doors while the auxiliary battery is connected.

  • Be sure to read the "PRECAUTION" thoroughly before servicing.
