operation
Fail-safe The ABS/TCS control unit turns the system off (ABS
mode-S1 fail-safe relay off) when the control unit detects a
problem.
Fail-safe If the ABS/TCS control unit detects a malfunction
mode-A2 while the TCS is operating, it will turn off the
malfunctioning component, and continue to
modulate the rest of the TCS system until
completing the TCS operation. At that time, the
TCS system will be turned off.
TCS deactivate If the front brake pad temperature rises excessively,
mode the ABS/TCS control unit stops the TCS system and
turns the TCS indicator on. When the brake pad
temperature lowers, the ABS/TCS control unit turns
off the TCS indicator and restarts the TCS system.
TCS OFF mode The ABS/TCS control unit cancels the TCS system
under these conditions:
• If the ABS/TCS control unit detects a problem
with the PGM-FI communication circuit.
• The ABS system is faulty.
• The TCS system is OFF.
If these conditions return to normal, the ABS/TCS
control unit restarts the TCS system.
On-board Diagnosis Function
The TCS 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.
