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
“DTC
Confirmation
Procedure”
has
been
previously
conducted, always turn ignition switch “OFF” and wait at least
5 seconds before conducting the next test.
With CONSULT-II
1) Start engine.
2) Select “DATA MONITOR” mode with CONSULT-II.
3) Set selector lever to “D” 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 “Diagnostic Procedure”, 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 “ECM Terminals and Reference Value” on the
previous page.
4) If NG, go to “Diagnostic Procedure”, EC-164.
