Troubleshooting
Step Action Yes No
1Was “Automatic Transaxle Diagnostic Flow
Tabl e ” performed?
Go to Step 2. Go to “Automatic Tran-
saxle Diagnostic Flow
Ta bl e ” in this section.
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 transmission
fluid temperature sensor at terminals E13-
11 and E13-12.
4) If OK, check continuity between terminals
E13-11 and E13-12 of disconnected har-
ness side TCM connector.
Is continuity indicated?
Go to Step 3. “BLU/RED” or “GRN/
RED” circuit open.
3 Check Transmission Fluid Temperature Circuit
for IG Short.

ring to “Transmission Fluid Temperature Sen-
sor” in this section.
Is result satisfactory?
Intermittent trouble or
faulty TCM.
Check for intermittent
