A/T 1ST GEAR FUNCTION

A/T 1ST GEAR FUNCTIONPFP:31940
DescriptionBCS00131

This malfunction will not be detected while A/T CHECK 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 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 LogicBCS00132

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 posi-
tion above
*: “A/T 1ST GR FNCTN” is detected.

Diagnostic trouble code “A/T 1ST GR FNCTN” with CONSULT-II is detected when A/T cannot be shifted
to the 1st gear position even if electrical circuit is good.

DTC Confirmation ProcedureBCS00134
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.
TESTING CONDITION:
Always drive vehicle on a level road to improve the accuracy of test.
After the repair, perform the following procedure to confirm that the malfunction is eliminated.
WITH CONSULT-II
1. Start engine and select “DATA MONITOR” mode for “A/T” with
CONSULT-II.
2. 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 vehicle to decrease the voltage (warm up
the fluid) or stop engine to increase the voltage (cool down the
fluid).
3. Select “1ST GR FNCTN P0731” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 20 to 25 km/h (12 to 16 MPH) under the following condition and release accelerator
pedal completely.
THROTTLE POSI: Less than 1.0/8 (at all times during step 4)
SLCT LVR POSI: “D” position
–Make sure that “GEAR” shows “2” after releasing pedal.
5. Depress accelerator pedal to WOT (more than 7.0/8 of “THROTTLE POSI”) quickly from a speed of 20 to
25 km/h (12 to 16 MPH) until “TESTING” changes to “STOP VEHICLE” or “COMPLETED”. (It will take
approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to AT- 1 3 8 , "
Diagnostic Procedure" .
If “STOP VEHICLE” appears on CONSULT-II screen, go to the following step.
–Make sure that “GEAR” shows “1” when depressing accelerator pedal to WOT.
–If “TESTING” does not appear on CONSULT-II for a long time, select “SELF-DIAG RESULTS” for
“A/T”. In case a 1st trip DTC other than “A/T 1ST GR FNCTN” is shown, refer to applicable “TROU-
BLE DIAGNOSIS FOR DTC”.
6. Stop vehicle.
7. Follow the instruction displayed. (Check for normal shifting referring to the table below.)
8. Make sure that “OK” is displayed. (If “NG” is displayed, refer to AT- 1 3 8 , "
Diagnostic Procedure" .)
Refer to AT- 5 4 , "
