DTC Troubleshooting
Step Action Yes No
1Was “A/T System Check” performed?Go to Step 2. Go to “A/T System
Check”.
2Check TCC 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 solenoid valve.
TCC 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 solenoid
valve or valve body
harness.
3Check TCC solenoid valve circuit for ground short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals “C06-
3” and “C06-5”.
3) If connection is OK, check continuity between terminal
“C06-5” of disconnected harness side TCM connector
and ground, between terminal “C06-3” 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.

resistance
Standard: 11 – 15 Ω at 20 °C (68 °F)Operation Check
Shift solenoid valve-A (No.1) and -B (No.2)
CAUTION!
• Do not insert air gun against strainer
installed on inlet of solenoid valve too
deeply, when blowing air into solenoid
valve. If not, the strainer will be damaged.
• Be very careful as dust etc. does not enter
when solenoid valves are inspected.

• Check that solenoid valve (1) actuate with click sound
when battery voltage is conducted.
• When solenoid valve (1) is connected to battery (2),
confirm that solenoid valve is close condition by
blowing air (50 – 200 kPa, 0.5 – 2.0 kg/cm
2, 7 – 28.5
psi) into solenoid valve as shown in figure.
• When solenoid valve (1) is not connected to battery
(2), confirm that solenoid valve is open condition by
blowing air (50 – 200 kPa, 0.5 – 2.0 kg/cm
2, 7 – 28.5
psi) into solenoid valve as shown in figure.
NOTE
Do not fail to inspect with air to prevent
mistaken checking because return spring for
valve is not installed into solenoid valve.
