Diagnostic ProcedureECS004RW
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out the value of “LINE PRES DTY” while driving.
Check the value changes according to driving speed.
Without CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between TCM connector terminal and ground.

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.
