TROUBLE DIAGNOSIS
t1 = 2.5 seconds t2 = 2.0 seconds t3 = 1.0 second
How to Erase Self-diagnostic Results
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait for at least
5 seconds and then turn it ON again.
2. Perform "Diagnostic Procedure Without CONSULT-III" .
3. Turn ignition switch OFF. (The se lf-diagnostic results will be erased.)
11th judgement flicker is longer than others.
Line pressure solenoid valve circuit is short-circuited or discon-
nected.
⇒ Go to AT- 1 3 3
. 12th judgement flicker is longer than others.
CAN communication line is damaged.
⇒ Go to
AT- 8 7
.
Lamp turns off.
Transmission range switch, overdrive control switch, closed throt-
tle position signal or wide open throttle position signal circuit is dis-
connected or TCM is damaged.
(Because overdrive control switch signal, closed throttle position
signal and wide open throttle position signal are input via CAN
communication line malfunction may continue after self-diagno-
sis.)

P0732 2GR INCORRECT RATIO
DescriptionINFOID:0000000005397294
• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosismalfunction.
• This malfunction is detected when the A/T does not shif t into second 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 Diagn osis LogicINFOID:0000000005397295
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0732 2GR INCORRECT RATIO” with CONSULT-III is detected when A/T cannot
be shifted to the 2GR 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 (2nd) 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 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 B stuck open: 4, 3*, 3 and 4 positions to each gear position
above
*: “P0732 2GR INCORRECT RATIO” is detected.
Possible CauseINFOID:0000000005397296
• Shift solenoid valve B
• Each clutch
