7B-80 AUTOMATIC TRANSAXLE
DTC Troubleshooting
Step
1
Was "Automatic Transaxle Diagnostic Flow
Table" performed?
2
Check TCC solenoid valve resistance
1) Turn ignition switch OFF
2) Disconnect valve body harness connector
on automatic transmission.
3) Check for proper connection to solenoid at
"WHT/BLU" circuit.
4) Check resistance of solenoid valve. See
Fig.
Resistance between TCC solenoid valve
terminals of transmission side valve body
harness connector: 11 – 15 Ω at 20°C
(68°F)
Resistance between TCC solenoid valve
terminals of transmission side valve body
harness connector and transmission body:
Infinity
Is check results satisfactory?
3
Check TCC solenoid valve circuit for ground
short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at ter-
minals "C39-5".
3) If connection is OK, check continuity
between terminal "C39-5" of disconnected
harness side TCM connector and ground.
Is continuity indicated?

Intermittent trouble or
faulty TCM. Check for
intermittent referring to
"Intermittent and Poor
