DIAGNOSTIC FUNCTION
TCM detects the ABS/ASC abnormality.
DESCRIPTIONS OF MONITOR METHODS
When the ABS/ASC error signal reception continues for 0.5 seconds.
MONITOR EXECUTION
- When 1.05 seconds have elapsed after TCM started (not during scan tool communication)
MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR)
