5. CHECK LOCK-UP (D4 TO D4 L/U)
Check lock-up (D
4 to D4 L/U).
Specified speed when lock-up occurs. Refer to AT- 5 3 0 , "
VEHICLE SPEED WHEN PERFORMING LOCK-UP"
.
Read vehicle speed, throttle opening when lock-up duty
becomes 94%. Refer to AT- 4 6 , "
DATA MONITOR MODE (A/T)" .
Does A/T perform lock-up at the specified speed?
YES >> GO TO 6.
NO >>

Mark the box on the “DIAGNOSTIC WORKSHEET”.
Refer to AT- 5 8
.

GO TO AT- 2 2 4 , "A/T Does Not Perform Lock-up" .

Continue “Road Test”.
6. CHECK LOCK-UP HOLD
Check lock-up hold.
When lock-up duty becomes 94%. Refer to AT- 4 6 , "
DATA MONITOR MODE (A/T)" .
Does A/T hold lock-up condition for more than 30 seconds?
YES >> GO TO 7.
NO >>

Mark the box on the “DIAGNOSTIC WORKSHEET”. Refer to AT- 5 8 .

GO TO AT- 2 2 5 , "A/T Does Not Hold Lock-up Condition" .

DTC U1000 CAN COMMUNICATION LINEPFP:31940
DescriptionECS008CZ
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
