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 a tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC in TCM memory.
3) Start engine and warm it up to normal operating temperature.
4) Shift select lever to “N” and “D” range for 10 seconds.
5) Start vehicle and increase vehicle speed to 65 km/h (40 mile/h) with throttle position 10% or more.
6) Stop vehicle and turn ignition switch OFF.
7) Repeat Step 3) to 5) one time.
8) Stop vehicle and check DTC.

2Check timing solenoid valve circuit for IG short
1) Disconnect TCM connectors.
2) Turn ignition switch ON and measure voltage between
terminal “C06-14” of harness side TCM connector and
ground.
Is it 0 – 1 V?Go to Step 3. “BLU/BLK” circuit
shorted to power circuit.
3Check timing solenoid valve circuit for open
1) Measure resistance between terminal “C06-14” of
disconnected harness side TCM connector and ground.
Is it 11 – 15
Ω at 20 °C (68 °F)?Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.Go to Step 4.
