1.
CHECK SHIFT SOLENOID VALVE
1.
Remove control valve assembly. Refer to
AT-410, "Control Valve Assembly and Accumulators"
.
2.
Check shift solenoid valve operation.
●
Shift solenoid valve B
Refer to
AT-146, "Component Inspection"
.
OK or NG
OK
>> GO TO 2
NG
>> Repair or replace shift solenoid valve assembly.
2.
CHECK CONTROL VALVE
1.
Disassemble control valve assembly. Refer to
AT-443, "Control Valve Assembly"
.
2.
Check to ensure that:
●
Valve, sleeve and plug slide along valve bore under their own weight.
●
Valve, sleeve and plug are free from burrs, dents and scratches.
●
Control valve springs are free from damage, deformation and fatigue.
●
Hydraulic line is free from obstacles.
OK or NG
OK
>> GO TO 3
NG
>> Repair control valve assembly.
3.
CHECK DTC
Perform
AT-142, "DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE"
.
OK or NG
OK
>> INSPECTION END
NG
>> Check control valve again. Repair or replace control valve assembly.

Description
ECS0097X
●
This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis.
●
This malfunction will not be detected while the O/D OFF indicator lamp is indicating another self-diagnosis
malfunction.
●
This malfunction is detected when the A/T does not shift into third 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, malfunctioning servo piston or brake band,
etc.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
ON BOARD DIAGNOSTIC LOGIC
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.
*: P0733 is detected.
