EBD Operation Electronic Brake Distribution (EBD) operation.
Fail-safe The ABS/TCS control unit turns the system off (ABS fail-
mode-S1 safe relay off) when the control unit detects a problem.
Fail-safe If the ABS/TCS control unit detects a malfunction while
mode-A1 the ABS, TCS, or EBD is operating, it will turn off the
malfunctioning component, and continue to modulate the
rest of the ABS system until completing the ABS, TCS, or
EBD operation. At that time, the entire system will be
turned off until the problem goes away.
Fail-safe If the ABS/TCS control unit detects a malfunction while
mode-A0 the ABS, TCS, or EBD is operating, it will turn off the
malfunctioning component, and continue to modulate the
rest of the ABS system until completing the ABS, TCS, or
EBD operation. At that time, the entire system will be
turned off until the problem goes away.
Fail-safe The ABS/TCS control unit stores a DTC in back-up
mode-L1 memory when it detects a problem. If a problem is
detected when the ignition switch is turned ON (II), the
ABS/TCS control unit will turn the system off. If the
problem goes away, the ABS/TCS control unit will turn
the system on again.
Fail-safe The ABS/TCS control unit stores a DTC in back-up
mode-L0 memory when it detects a problem. If a problem is
detected when the ignition switch is turned ON (II), the
ABS/TCS control unit will turn only the ABS system off. If
the problem goes away, the ABS/TCS control unit will
turn the ABS system on again.
Fail-safe The ABS/TCS control unit will turn the system off, if the
mode-B1 ignition voltage drops, and will turn it on again when the
ignition voltage returns to normal.
Fail-safe The ABS/TCS control unit will turn only the ABS system
mode-B0 off, if the ignition voltage drops, and will turn it on again
when the ignition voltage returns to normal.
On-board Diagnosis Function
The ABS can be diagnosed with the HDS.
The ALB Checker cannot be used with this system. For air bleeding, and checking wheel sensor signals, use the HDS.
See the HDS help menu for specific operating instructions.
