Diagnostic ProcedureECS007RV
1.CHECK DTC WITH ECM
●Check DTC with CONSULT-II “ENGINE”.
Turn ignition switch ON and select “SELF DIAGNOSTIC RESULTS” mode for “ENGINE” with CONSULT-II.
Refer to EC-37, "
Emission-related Diagnostic Information" (EURO OBD) or EC-429, "Emission-related Diag-
nostic Information" (Except EURO OBD).
OK or NG
OK (With CONSULT-II)>>GO TO 2
OK (Without CONSULT-II)>>GO TO 3
NG >> Perform trouble diagnosis for the DTC for engine control.
2.CHECK INPUT SIGNAL (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “THRTL POS SEN”.
OK or NG
OK >> GO TO 4
NG >> Check harness for short or open between ECM and TCM regarding throttle position sensor circuit.

3. CHECK INPUT SIGNAL (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 41 and 48 while acceler-
ator pedal is depressed slowly.
(Voltage rises gradually in response to throttle position.)
OK or NG
OK >> GO TO 4
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit.
4. CHECK DTC
Perform AT-353, "
SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Voltage:
Fully-closed throttle valve :Approximately 0.5V
Fully-open throttle valve :Approximately 4V

Shift solenoid valves A and B are turned “ON” or “OFF” by the TCM
in response to signals sent from the PNP switch, vehicle speed and
throttle position sensors. Gears will then be shifted to the optimum
position.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle in D
1→ D2 position.
4. IF DTC is detected, go to AT- 3 6 0 , "

Diagnostic Procedure
ECS007RY
1. CHECK VALVE RESISTANCE
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminal 2 and ground.
OK or NG
OK >> GO TO 2
NG >> 1. Remove control valve assembly. Refer to AT- 4 0 6 ,
"Control Valve Assembly and Accumulators" .
2. Check the following items:
Shift solenoid valve A
Refer to AT-360, "
Component Inspection" .
Harness of terminal cord assembly for short or open
2. CHECK POWER SOURCE CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check continuity between terminal 2 and TCM harness connector terminal 11.
If OK, check harness for short to ground and short to power.
4. Reinstall any part removed.
OK or NG
OK >> GO TO 3
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
