ADDITIONAL EXPLANATION OF FAIL-SAFE
1. Warning lamp initial lighting time
1. Immediately after IG-SW ON, warning lamp is lit for 3 sec. This term is called, warning lamp initial lighting time.
2. Within this term, in case that the ECM detects the failure, warning lamp is lighted continuously.

NOTE
1. System down
The system changes to normal braking with warning lamp ON after detecting the failure by its software. ECM restart is caused by IG-SW OFF -> ON once.
After the failure is corrected, the ECM returns a to normal mode with warning lamp OFF.
2. All wheel inhibit
ECM discontinues ABS control of all wheels. (Equivalent to normal brake)
When the failure is corrected, it returns to normal mode with warning lamp OFF. (But during ABS control, it does not return to a normal mode.)
