DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Clear DTC.
2) Start engine and run it for 30 seconds.
3) Check DTC.
DTC Troubleshooting
3 Check “3” position switch circuit
1) Measure voltage between “C07-9” terminal of TCM
connector and ground.
“3” position switch specifications
Shift select lever to “3” or “2” range: Battery voltage
Shift select lever to other above range: 0 V
Is check result satisfactory?
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”. If OK, substitute a
known-good TCM and
recheck. “YEL” wire is open or
shorted to ground. If
wire is OK, replace “3”
position switch.

1) Measure voltage between “C06-5” terminal of harness
side TCM connector and ground with ignition switch
turned ON.
Is it 0 – 2 V?
Go to Step 3. “WHT/BLU” circuit
shorted to power circuit
or open.
