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 failure 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 failures are not recorded in the memory of the ABS ECU (e.g., a drop in battery volt-
age).
