A/T 3RD GEAR FUNCTIONPFP:31940
DescriptionBCS0013B

This malfunction will not be detected while A/T CHECK indicator lamp is indicating another self-diagnosis
malfunction.

This malfunction is detected when A/T does not shift into third gear position as instructed by TCM. This is
not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as con-
trol valve sticking, improper solenoid valve operation, malfunctioning servo piston or brake band, etc.
On Board Diagnosis LogicBCS0013C

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 (3rd) 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 shift solenoid valve A is stuck closed.

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 closed: 1, 1, 4* and 4 positions to each gear
position above
*: “A/T 3RD GR FNCTN” is detected.

Diagnostic trouble code “A/T 3RD GR FNCTN” with CONSULT-II is detected when A/T cannot be shifted
to the 3rd gear position even if electrical circuit is good.

Vehicle Does Not Decelerate By Engine Brake (D4 → 33 )BCS0014S
SYMPTOM:
Vehicle does not decelerate by engine brake when A/T selector lever is in “3” position on “Cruise
Test— Part 3”.
DIAGNOSTIC PROCEDURE
1. CHECK 3RD POSITION SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out “OVERDRIVE SW” switch moving selector lever to
each position.
Without CONSULT-II
1. Turn ignition switch ON. (Do not start engine)
2. Check voltage between A/T device harness connector terminal
and ground. Refer to AT- 1 6 8 , "
Wiring Diagram — AT — NON-
DTC" .
OK or NG
OK >> GO TO 2.
NG >> Check 3rd position switch. Refer to AT- 1 6 6 , "
3RD POSITION SWITCH" .
2. CHECK ACCELERATOR PEDAL POSITION SENSOR
Check accelerator pedal position sensor. Refer to EC-272, "
DTC P2138 APP SENSOR" (QR engine) or EC-
652, "DTC P2138 APP SENSOR" (VQ engine).
OK or NG
OK >> GO TO 3.
NG >> Repair or replace accelerator pedal position sensor.
3. CHECK VEHICLE SPEED SENSOR·A/T AND VEHICLE SPEED SENSOR·MTR CIRCUIT
Check vehicle speed sensor·A/T (revolution sensor) and vehicle speed sensor·MTR circuit. Refer to AT- 8 0 ,
"VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)" and AT- 8 6 , "VEHICLE SPEED SENSOR MTR"
.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace vehicle speed sensor·A/T (revolution sensor) and/or vehicle speed sensor·MTR
circuits.
