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 (M.U.T.-IIISE) communication).
MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR)
Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
- P0712, P0713: Malfunction of the transmission fluid temperature sensor
- P0715: Malfunction of primary pulley speed sensor
- P0720: Malfunction of secondary pulley speed sensor
- P0730: Incorrect gear ratio
- P0966, P0967: Malfunction of secondary pressure solenoid valve
- P0970, P0971: Malfunction of primary pressure solenoid valve
- P2720, P2721: Malfunction of select pressure solenoid valve
- P2763, P2764: Malfunction of lock-up solenoid valve
- P2765: Malfunction of turbine speed sensor
Sensor (The sensor below is determined to be normal)
- Transmission fluid temperature sensor
- Primary pulley speed sensor
- Secondary pulley speed sensor
- Turbine speed sensor
LOGIC FLOW CHARTS (Monitor Sequence)
DTC SET CONDITIONS
Check Conditions
- Time after TCM start: More than 1.05 seconds.
Judgment Criteria
- ABS status: Malfunction (0.5 second).
OBD-II DRIVE CYCLE PATTERN
Ignition switch: ON (start the engine and keep it for 10 seconds or more, not during scan tool communication).
PROBABLE CAUSES
- Malfunction of the ABS/ASC system
- Malfunction of TCM
