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”.
