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
transaxle.
“BRN” circuit shorted to
power circuit or open, or
“BLK/YEL” circuit
shorted to ground. If
wire is OK, go to Step 4.
4 “3” position switch signal inspection
1) With ignition switch turned ON, check voltage between
“L01-8” terminal of BCM coupler and ground.
“3” position switch signal specification
Shift select lever to “3” or “2” range: 8 – 14 V
Shift select lever to other above range: 0 – 1 V
Is result as specified? Substitute a known-
good TCM and recheck.

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.
