DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC in TCM memory.
3) Start engine and shift select lever to “N” range.
4) Repeat shifting select lever from “N” range to “D” range and vice versa for 3 times.
5) Check DTC.
DTC Troubleshooting
Step Action Yes No
1Was “A/T System Check” performed?Go to Step 2. Go to “A/T System
Check”.
2Check timing solenoid valve resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector (1), (2) on
transaxle.
3) Check for proper connection to solenoid valve at “BLU/
BLK” circuit.
4) Check resistance of solenoid valve.
Timing solenoid valve resistance
Between terminal of transaxle side valve body
harness connector and transaxle: 11 – 15 Ω at 20 °C
(68 °F)
Is check result satisfactory?Go to Step 3. Replace timing solenoid
valve or lead wire.
3Check timing solenoid valve circuit for ground short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Measure resistance between terminal “C06-14” of
disconnected harness side TCM connector and ground.
Is it 11 – 15
Ω at 20 °C (68 °F)?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.“BLU/BLK” circuit
shorted to ground.

Step Action Yes No
1Was “A/T System Check” performed?Go to Step 2. Go to “A/T System
Check”.
2Check timing solenoid valve circuit for IG short
1) Disconnect TCM connectors.
2) Turn ignition switch ON and measure voltage between
terminal “C06-14” of harness side TCM connector and
ground.
Is it 0 – 1 V?Go to Step 3. “BLU/BLK” circuit
shorted to power circuit.
3Check timing solenoid valve circuit for open
1) Measure resistance between terminal “C06-14” of
disconnected harness side TCM connector and ground.
Is it 11 – 15
Ω at 20 °C (68 °F)?Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
