System Description
These circuit lines are used to control the smooth shifting up and down of A/T during the hard acceleration/
deceleration.
Voltage signals are exchanged between ECM and TCM (Transmission control module).
ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC Confirmation Procedure
NOTE:
If ªDTC Confirmation Procedureº has been previously
conducted, always turn ignition switch ªOFFº and wait at least
5 seconds before conducting the next test.
With CONSULT-II
1) Start engine.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Set selector lever to ªDº position.
4) Accelerate up to 60 km/h (37 MPH) gradually on the accelera-tor pedal.
Do not accelerate with shift down.
5) Stop the vehicle with engine running.
6) If DTC is detected, go to ªDiagnostic Procedureº, EC-164.
Overall Function Check
Use this procedure to check the overall function of the A/T control
circuit. During this check, a DTC might not be confirmed.
Without CONSULT-II
1) Start engine.
2) Read the voltage signal between ECM terminals 24, 30, 37, 58 and ground with an oscilloscope.
3) Verify that the oscilloscope screen shows the signal wave as shown under ªECM Terminals and Reference Valueº on the
previous page.
4) If NG, go to ªDiagnostic Procedureº, EC-164.

Diagnostic Procedure
1 CHECK INPUT SIGNAL CIRCUIT
1. Turn ignition switch ªOFFº.
2. Disconnect ECM harness connector and TCM (Transmission control module) harness connector.
MEC020E
MEC026E
3. Check harness continuity between the following terminals. Refer to Wiring Diagram.
MTBL0532
Continuity should exist.OK or NG
OK EGO TO 3.
NG EGO TO 2.
2 DETECT MALFUNCTIONING PART
Check the following.
IHarness connectors M788, F93 (LHD models)
I Harness for open or short between ECM and TCM (Transmission control module)
ERepair harness or connectors.

3 CHECK INPUT SIGNAL CIRCUIT
1. Check harness continuity between ECM terminal 24 and ground, ECM terminal 30 and ground, ECM terminal 37 and ground,ECM terminal 58 and ground. Refer to Wiring Diagram. Continuity should not exist.
2. Also check harness for short to ground and short to power.
OK or NG
OK EGO TO 5.
NG EGO TO 4.
4 DETECT MALFUNCTIONING PART
Check the harness for open or short between ECM and TCM (Transmission control module).
ERepair open circuit short to ground or short to power in harness.
5 CHECK INTERMITTENT INCIDENT
Refer to ªTROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENTº, EC-78.
