DTC U1000 CAN COMMUNICATION LINE
DescriptionINFOID:0000000001703195
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 malfunction detection ability.
Many electronic 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 con-
nected 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.

DTC P0731 A/T 1ST GEAR FUNCTION
DescriptionINFOID:0000000001703231
• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosis
malfunction.
• This malfunction is detected when the A/T does not shift into first gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as
control valve sticking, improper solenoid valve operation, etc.
On Board Diagnosis LogicINFOID:0000000001703232
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0731 A/T 1ST GR FNCTN” with CONSULT-III is detected when A/T cannot be
shifted to the 1st gear position even if electrical circuit is good.
• This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (1st) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when either shift solenoid valve A is stuck open or shift solenoid valve B is
stuck open.
• Gear positions supposed by TCM are as follows:
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift solenoid valve A stuck open: 2*, 2, 3 and 3 positions
In case of gear position with shift solenoid valve B stuck open: 4*, 3, 3 and 4 positions to each gear position
above
*: “P0731 A/T 1ST GR FNCTN” is detected.
Possible CauseINFOID:0000000001703233
• Shift solenoid valve A
• Shift solenoid valve B
• Each clutch
• Hydraulic control circuit
DTC Confirmation ProcedureINFOID:0000000001703234
CAUTION:

After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start engine and select “DATA MONITOR” mode for “A/T” with CONSULT-III.
2. Touch “START”.
3. Make sure that output voltage of A/T fluid temperature sensor is within the range below.
FLUID TEMP SE: 0.4 - 1.5 V
If out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to increase the
voltage (cool down the fluid).
4. Select “1ST GR FNCTN P0731” of “DTC WORK SUPPORT” mode for “A/T” with CONSULT-III and touch
“START”.
