DTC Confirmation Procedure
WARNING:
If you do not select a suitable route and take proper precautions when performing a road test, an accident can occur.
•Select a level road with no traffic to minimize the risk of accident.
•Perform the test extremely carefully.
•Perform the road test with 2 persons, a driver and a tester.
•Perform the test extremely carefully.
•Perform the road test with 2 persons, a driver and a tester.
NOTE:
Check that the following conditions are satisfied in this procedure.
•11 V < Battery voltage < 15 V
1)Start engine and drive vehicle.
DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
DTC check
1)Clear DTC.
2)Set ignition “OFF.”
3)Perform “DTC Confirmation Procedure”, and check DTC.
Is the same DTC still detected?
|
Replace solenoid valve unit.
If this DTC is detected again, replace TCM and recheck DTC.
|
Check for intermittent trouble.
