TROUBLE DIAGNOSIS
Check for time difference between actual shift timing and the CONSULT-III display. If the difference is
noticeable, mechanical parts (except solenoids, sens ors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) display ed on CONSULT-III and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
- Actual shift schedule has more or less tolerance or allowance,
- Shift schedule indicated in Service Manual refers to the point where shifts start, and
- Gear position displayed on CONSULT-III indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSUL T-III at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000005928107
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 communica tion 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 li ne) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.
On Board Diagnosis LogicINFOID:0000000005928108
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1000 CAN COMM CIRCUIT” wit h CONSULT-III or 12th judgement flicker without

P0731 1GR INCORRECT RATIO
DescriptionINFOID:0000000005928143
• 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 shif t into first gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuit s open or shorted) but by mechanical malfunction such as
control valve sticking, improper solenoid valve operation, etc.
On Board Diagnosis LogicINFOID:0000000005928144
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0731 1GR INCORRECT RATIO” with CONSULT-III is detected when A/T cannot
be shifted to the 1GR position even if electrical circuit is good.
• This diagnosis monitors actual gear position by checki ng the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from output speed 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 specif ied 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 1GR INCORRECT RATIO” is detected.
Possible CauseINFOID:0000000005928145
• Shift solenoid valve A
• Shift solenoid valve B
• Each clutch
• Hydraulic control circuit
DTC Confirmation ProcedureINFOID:0000000005928146
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start engine and select “DATA MONITOR” m ode for “TRANSMISSION” 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 vo ltage (warm up the fluid) or stop engine to increase the
voltage (cool down the fluid).
4. Select “1ST GR FNCTN P0731” of “DTC & SR T CONFIRMATION” mode for “TRANSMISSION” with
CONSULT-III and touch “START”.
