Brake Pressure Too High (Brake Booster) Component Failure |
Fluid pressure control performance degraded (pressure excessively high) |
|
Comes on |
|
MONITOR DESCRIPTION
The No. 2 skid control ECU (brake actuator assembly) monitors the relationship between the specified decrease in servo pressure and the target brake fluid pressure.
When the brake pedal is released or while braking is being performed and the relationship between the servo pressure and the target brake fluid pressure is outside of the normal range, the No. 2 skid control ECU (brake actuator assembly) judges that the decreasing pressure is abnormal and illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN
NOTICE:
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
HINT:
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off.
- Turn the ignition switch to ON (READY) and turn the GTS on.
- Drive the vehicle at 3 km/h (2 mph) or more for 1 second. [*1]
- Turn the ignition switch off. [*2]
- Wait 4 minutes. [*3]
- Turn the ignition switch to ON (READY). [*4]
-
Depress the brake pedal for 2 seconds, release it and wait 1 second. [*5]
HINT:
[*1] to [*5]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Chassis / Brake/EPB / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
CAUTION / NOTICE / HINT
NOTICE:
After replacing the No. 1 skid control ECU (brake booster with master cylinder assembly), perform "Calibration" after performing "Reset Memory".
