INSPECTION CHART FOR THROUBLE SYMPTOMS
Trouble symptom
Communication with HI-SCAN is not possible
is not functioning.
Driving impossible Starting impossible
Starting is not possible when the selector lever
is in P or N range. In such cases, the cause is
probably a defective engine system, torque
converter or oil pump.
Does not move forward
If the vehicle does not move forward when the
selector lever is shifted from N to D range while
the engine is idling, the cause is probably
abnormal line pressure or a malfunction of the
underdrive clutch or valve body.
Does not reverse
If the vehicle does not reverse when the
selector lever is shifted from N to R range while
the engine is idling, the cause is probably
abnormal pressure in the reverse clutch or low
and reverse brake or a malfunction of the
reverse clutch, low and reverse brake or valve
body.
Does not move (forward or reverse)
If the vehicle does not move forward or reverse
when the selector lever is shifted to any
position while the engine is idling, the cause is
probably abnormal line pressure or a
malfunction of the power train, oil pump or
valve body.
