Troubleshooting
Step
1 Was "Automatic Transaxle Diagnostic Flow
Table" performed?
2 Check Transmission Fluid Temperature Circuit
for Open.
1) Turn ignition switch OFF.
2) Disconnect TCM connectors from TCM.
3) Check for proper connection to transmis-
sion fluid temperature sensor at terminals
C39-11 and C39-12.
4) If OK, check continuity between terminals
C39-11 and C39-12 of disconnected har-
ness side TCM connector.
Is continuity indicated?
3 Check Transmission Fluid Temperature Circuit
for IG Short.
1) Cool down A/T fluid temperature under
ambient temperature.
2) Connect TCM connectors to TCM with igni-
tion switch OFF.
3) Turn ignition switch ON.
4) Measure voltage between terminal C39-11
of TCM connector and ground.
Is it 4.6 V or more?
4 Inspect Transmission Fluid Temperature Sen-
sor.
Inspect transmission temperature sensor refer-
ring to "Transmission Fluid Temperature Sen-
sor
Is result satisfactory?
Action Yes
Go to Step 2.
Go to Step 3.
