No Lock-Up OccursS7RS0B5104020
System Description
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
/ P0977 / P1702 / P1703 / P1774 / P1777 / P2762 / P2763 / P2764
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.
Faulty “3” position
switch or its circuit.
Step Action Yes No

2Check TCC lock-up pressure control solenoid valve
resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector (1), (2) on
automatic transaxle.
3) Check for proper connection to solenoid at “WHT/BLU” and “WHT/BLK” circuits.
4) Check resistance of TCC lock-up pressure control
solenoid valve.
TCC lock-up pressure control solenoid valve
resistance
Between shift terminals of transaxle side valve body
harness connector: 5.0 – 5.6 Ω at 20 °C (68 °F)
Between shift terminals of transaxle side valve body
harness connector and transaxle: Infinity
Is check results satisfactory? Go to Step 3. Replace TCC lock-up
pressure control
solenoid valve or lead
wire.
3 Check TCC lock-up pressure control solenoid valve
circuit for ground short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals “C34-
3” and “C34-5”.
3) If connection is OK, check continuity between terminal
“C34-5” of disconnected harness side TCM connector
and ground, between terminal “C34-3” of disconnected
harness side TCM connector and ground.
Are continuity indicated? “WHT/BLU” or “WHT/
BLK” circuit shorted to
ground.
Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.
Step Action Yes No

• With ignition switch turned to ACC position, push
shift lock solenoid release button (1). Then, select
lever can be shifted from “P” range position to any
other range.
• While ignition switch is at LOCK position, even when shift lock solenoid release button (1) is
pressed, select lever cannot be shifted from P
range position to any other range.
• When ignition switch is turned ON and brake pedal is depressed, select lever can be shifted
from “P” range position to any other range. 3) With select lever shifted to any position other than
“P” range, check that ignition key cannot be turned
LOCK position and it cannot be removed from
ignition switch unless it is at LOCK position.
