5A-46 Automatic Transmission/Transaxle:
DTC Troubleshooting
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check”.
2 Check TCC solenoid valve circuit for IG short
1) Turn ignition switch ON and measure voltage between
terminal “G08-12” of harness side TCM connector and
ground.
Is it 0 – 2 V?
Go to Step 3. “BLU/WHT” circuit
shorted to power circuit
or open.
3 Check TCC solenoid valve resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector (1) on
transaxle (3).
3) Check for proper connection to solenoid at “BLU/WHT”
circuit.
4) Check resistance of solenoid.
TCC solenoid valve resistance
Between terminal (2) of transaxle side valve body
harness connector and transaxle: 11 – 15
Ω
(at 20
°
C
(68
°
F))
Is check result satisfactory?
Go to Step 4. Replace shift solenoid
valve or lead wire.
4 Check TCC solenoid circuit for ground short
1) Connect valve body harness connector.
2) Measure resistance between terminal “G08-12” 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
in related manual”.
If OK, substitute a
known-good TCM and
recheck. “BLU/WHT” circuit
shorted to ground.
