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 32 (ECM ground).

On Board Diagnosis Logic:

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
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT.
3. Start engine, and rev engine more than 1,000 rpm once, then let it idle for more than 40 seconds.
4. If DTC is detected, go to "Diagnostic Procedure" below.




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
1. Start engine.
2. Check voltage between
ECM terminal 26 and ground.
ECM terminal 27 and ground.
Voltage: 6 - 8V

3. If NG, go to "Diagnostic Procedure" below.
