CAUTION:
Perform each part replacement carefully, as mistakes could affect the brake system performance and lead to driving problems. When replacing a part, replace with the same part or equivalent.
Note
As these procedures may affect the SRS airbags, it is necessary to read the SRS airbag precautions.
While the battery is connected, even if the engeni switch is off, the brake control system activates when the brake pedal is depressed with the door courtesy switch on. Therefore during servicing of the brake system components, do not operate the brake pedal and open/close the doors while the battery is connected.
Do not operate the electric parking brake switch with the battery connected, unless otherwise instructed in the procedures.
Make sure that the electric parking brake AUTO switch is off. This is necessary to prevent the system from activating when the shift lever is moved.
After turning the engine switch off, thee parking brake ECU assembly and parking brake actuator assembly operate for 20 seconds. If a connector is disconnected within this period, a DTC may be output.
When servicing the brake system, make sure its parts and surrounding parts are clean.
