TCM turns TCC solenoid OFF under any of the following conditions.
• Brake light switch is turned ON (Brake pedal is depressed).
• Transmission fluid temperat ure is less than 60 °C (140 °F).
• Throttle opening is as much as 0%.
• TCM detects the following DTCs. P0705 / P0707 / P0712 / P0713 / P0717 / P0722 / P0787 / P0788 / P0961 / P0962 / P0963 / P0973 / P0974 / P0976

Troubleshooting
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

3 1) Perform running test under the following conditions and measure voltage between terminal “C34-16” of TCM
connector and ground, terminal “C34-15” of TCM
connector and ground.
• Engine coolant temperature is in normal operating temperature.
• Select lever is in “D” range.
• Drive vehicle with 4th gear condition referring to “Automatic Gear Shift Table”.
Voltage between TCM connector and ground
Between terminal “C34-16” of TCM connector and
ground: 0 – 1 V
Between terminal “C34-15” of TCM connector and
ground: 8 – 14 V
Do results satisfy the value? Faulty shift solenoid
valve, circuit or
