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 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?
