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 met in this “DTC Confirmation Procedure”.
—A/F feedback (closed loop) control is activated.
—Battery voltage > 11 V
•Check that the following DTCs are not detected in this “DTC Confirmation Procedure”.—Battery voltage > 11 V
—HO2S-1 heater (P0030, P0031 and P0032)
—HO2S-2 (P0137, P0138 and P0140)
