ABS Components
System Description (cont’d)
1. The ABS control unit is equipped with a main CPU and a sub-CPU. Each CPU checks the other for problems.
2. The CPUs check the circuit of the system.
3. Self-diagnosis can be classifield into 2 categories:
• Initial diagnosis: Done right after the engine starts and until the ABS indicator goes off.
• Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned OFF.
4. When a problem is detected by self-diagnosis, the system shifts to fail-safe mode.

• If the ABS control unit detects the DTCs which have different fail-safe mode individually, the control unit take
priority the large number mode.
