DESCRIPTION
These solenoids turn on when signals are received from the skid control ECU and they control the pressure acting on the wheel cylinders to control the braking force.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
-
When replacing the brake actuator assembly, perform zero point calibration and store system information (See page
![2016 - 2017 MY Sienna [12/2015 - 11/2017]; BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: CALIBRATION](/t3Portal/stylegraphics/info.gif)
).
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
PROCEDURE
|
1. |
RECONFIRM DTC |
HINT:
These codes are detected when a problem is determined in the brake actuator assembly.
The solenoid circuits are in the brake actuator assembly.
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if any DTCs are output before replacing the brake actuator assembly.
(a) Clear the DTCs (See page
).
(b) Start the engine.
(c) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(d) Check if the same DTC is recorded (See page
).

DTCs (C0226, C0236, C0246, C0256 and C1225) are not output |

DTCs (C0226, C0236, C0246, C0256 and/or C1225) are output |
B |
HINT:
- If a speed signal of 6 km/h (4 mph) or more is input to the skid control ECU with the ignition switch to ON and the stop light switch off, the ECU performs self diagnosis of the motor and solenoid circuits.
- If the normal system code is output (no trouble codes are output), slightly jiggle the connectors, wire harness, and fuses of the brake actuator assembly. Make sure that no DTCs are output.
- If any DTCs are output while jiggling a connector or wire harness of the brake actuator assembly (skid control ECU), inspect and repair the connector or wire harness.
- The DTCs were possibly output due to a bad connection of the connector terminal.
