DTC Detecting Condition and Trouble Area
DTC Detecting Condition
Voltage of TCC pressure control solenoid valve TCM terminal is
low although TCM is commanding TCC pressurie control solenoid
to turn ON.
(1 driving cycle detection logic)
DTC Confirmation Procedure
WARNING
!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and tester, on a level road.
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine.
4) Keep engine running at idle speed in "P" range for 20 seconds or more.
5) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check TCC pressure control solenoid valve circuit for
ground short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals "E92-
3" and "E92-5".
3) If connection is OK, check continuity between terminal
"E92-5" of disconnected harness side TCM connector
and ground.
Is continuity indicated?
3 Check TCC pressure control solenoid valve circuit for
open
1) Check resistance between terminal "E92-3" and "E92-5"
of disconnected harness side TCM connector.
Is it infinity?
4 Inspection TCC pressure control solenoid valve
1) Inspection TCC pressure control solenoid valve referring
to "Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B,
TCC Pressure Control Solenoid and Pressure Control
Solenoid Inspection: ".
Is check results satisfactory?

• TCC pressure control solenoid valve circuit
open or shorted to ground.
• Malfunction of TCC pressure control solenoid
valve
• TCM
Yes
Go to Step 2.
TCC pressure control
solenoid valve circuit is
shorted to ground. If
circuit is OK, go to Step
4.
TCC pressure control
solenoid valve circuit is
open. If circuit is OK, go
to Step 4.
Intermittent trouble or
faulty TCM. Check for
intermittent trouble
referring to "Intermittent
and Poor Connection
Inspection: in Section
00". If OK, substitute a
known-good TCM and
recheck.
