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

HINT:
DTC will be output when conditions for any of the patterns in the table above are met.
CAUTION / NOTICE / HINT
NOTICE:
When replacing the skid control ECU (brake actuator assembly), perform zero point
calibration and store system information (See page
).
PROCEDURE
1. |
RECONFIRM DTC |
HINT:
These codes are detected when a problem is determined in the skid control ECU (brake actuator assembly).
The solenoid circuits are in the skid control ECU (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 skid control ECU (brake actuator assembly).
(a) Clear the DTC (See page
).
(b) Turn the ignition switch off.
(c) Start the engine.
(d) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(e) Check if the same DTC is recorded (See page
).

System Description
SYSTEM DESCRIPTION
GENERAL
The cruise control main switch is used to turn the dynamic radar cruise control
system on and off, as well as operate 7 functions: SET, - (COAST), TAP-DOWN, RES
(RESUME), + (ACCEL), TAP-UP and CANCEL. The SET, TAP-DOWN, and - (COAST) functions,
and the RES (RESUME) ...
Brake Switch "A" Signal Compare Failure (P057162)
DESCRIPTION
When the brake pedal is depressed, stop light switch assembly sends a signal
to the ECM. Upon receiving the signal, the ECM cancels the cruise control system.
