NOTE: While the battery is connected, even if the power switch is OFF, the brake control system activates when the brake pedal is depressed or the door courtesy switch turns on. Therefore during servicing of the brake system components, do not operate the brake pedal or open/close the doors while the battery is connected.

HINT:

The procedures listed below are for the RH side.
Other than areas where instructions are provided, use the same procedures for the LH side and RH side.
