The necessary actions are confirmed using the monitor circuit and control signals are transmitted to the
hydraulic unit and ABS motor relay.
ABS control operation
The ABS control operation performed in the ABS ECU is divided into the following two parts.
• Hydraulic control
• Self-diagnosis
These operations are performed once every 8/1000th of a second. When a malfunction is detected in
the ABS, a malfunction code is stored in the memory of the ABS ECU for easy problem identification
and troubleshooting.
NOTE:
Some types of malfunctions are not recorded in the memory of the ABS ECU (e.g., a drop in battery
voltage).
