Monitor Description | Description
of what the skid control ECU (brake booster with master cylinder
assembly) monitors and how it detects malfunctions (monitoring purpose
and details). |
| Related DTCs |
Group
of diagnostic trouble codes that are output by the skid control ECU
(brake booster with master cylinder assembly) based on the same
malfunction detection logic. |
|
Typical Enabling Conditions | Preconditions that allow the skid control ECU (brake booster with master cylinder assembly) to detect malfunctions.
With
all preconditions satisfied, the skid control ECU (brake booster with
master cylinder assembly) stores a DTC when the monitored value(s)
exceeds the malfunction threshold(s). |
|
Sequence of Operation | The priority order that is applied to monitoring if multiple sensors and components are used to detect the malfunction.
While one sensor is being monitored, the next sensor or component will not be monitored. |
|
Required Sensors/Components | The
sensors and components that are used by the skid control ECU (brake
booster with master cylinder assembly) to detect malfunctions. |
|
Frequency of Operation | The
number of times that the skid control ECU (brake booster with master
cylinder assembly) checks for malfunctions per driving cycle. "Continuous"
means that the skid control ECU (brake booster with master cylinder
assembly) checks for malfunctions every time the enabling conditions are
met. "During initial checking" means that the skid
control ECU (brake booster with master cylinder assembly) checks for
malfunctions for approximately 3 seconds after the power switch is
turned on (IG) (while the initial check being performed). "After
power switch off" means that after the power switch is turned off, the
system check which is performed using residual power checks for
malfunctions that are difficult to detect during normal operation,
within a certain amount of time. |
|
Duration | The
minimum time for which the skid control ECU (brake booster with master
cylinder assembly) must detect a continuous deviation in the monitored
value(s) in order to store a DTC. Timing begins after the "typical
enabling conditions" are met. |
|
Typical Malfunction Thresholds | Value
beyond which the skid control ECU (brake booster with master cylinder
assembly) will determine that there is a malfunction and stores a DTC. |
|
MIL Operation | MIL illumination timing after a malfunction is detected.
"Immediate"
means that the skid control ECU (brake booster with master cylinder
assembly) illuminates the MIL the instant the skid control ECU (brake
booster with master cylinder assembly) determines that there is a
malfunction. |
| Component Operating Range |
Normal operation range of sensors and solenoids under normal driving conditions.
Use these ranges as a reference. They cannot be used to judge if a sensor or solenoid is defective or not. |
