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 and shift selector lever to “D” range.
4) Start vehicle and increase vehicle speed until gear
position reaches 3rd or 4th gear.
5) Decrease vehicle speed and stop vehicle.
6) Repeat Step 4) to 5) 2 times or more.

DTC detecting condition Trouble area
• Voltage of shift solenoid valve TCM terminal is low
although TCM is commanding shift solenoid valve to turn
ON.
• Voltage of shift solenoid valve TCM terminal is high
although TCM is commanding shift solenoid valve to turn
OFF.
• Shift solenoid valve circuit shorted to ground
• Shift solenoid valve circuit open or shorted to power
circuit
• Malfunction of shift solenoid valve
• TCM
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check”.
2 Check shift solenoid valve circuit for IG short
1) Turn ignition switch OFF and disconnect TCM
connectors.
2) Check for proper connection to TCM at terminal “G08-4”
or “G08-3” of TCM connector.
3) If OK, turn ignition switch ON and measure voltage
between terminal “G08-4” or “G08-3” of disconnected
harness side TCM connector and ground.
Is it 0 – 1 V?
Go to Step 3. “GRY” or “GRN/ORN”
circuit shorted to power
circuit.
