DTC Confirmation Procedure

NOTE:

Confirm that the following conditions are met in this "DTC Confirmation Procedure".

- Battery voltage >= 11 V

1) Push engine switch to change ignition mode to "ON" and leave ignition mode in "ON" for 5 sec.

DTC Troubleshooting

1. Was "Engine and Emission Control System Check" performed?
YES
Go to Step 2.
NO
Go to Engine and Emission Control System Check Engine and Emission Control System Check.
2. EVAP leak detection pump operation check
Check operating sound of EVAP leak detection pump referring to "EVAP Leak Detection Pump Circuit Check" under Testing and Inspection EVAP Leak Check Module Circuit Inspection.
Is operating sound heard?
YES
Go to Step 4.
NO
Go to Step 3.
3. Detection pump circuit check
Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C01", "E01" and EVAP leak check module connectors.
Check for proper terminal connection to "C01", "E01" and EVAP leak check module connectors.
If connections are OK, check that EVAP leak detection pump drive circuit (C1) and ground circuit (C2) is as follows.
Resistance of "C1" and "C2" circuits: less than 1
Resistance of "C1" and "C2" circuits between EVAP leak check module connector and ground: infinity
Resistance between each of "C1" and "C2" circuit terminals and each terminal at EVAP leak check module connector: infinity
Voltage of "C1" and "C2" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON".)
Are they in good condition?
YES
Go to Step 4.
NO
Repair or replace defective wire harness.
4. EVAP leak detection pump check
Check EVAP leak detection pump referring to "EVAP Leak Detection Pump Inspection" under EVAP Leak Check Module Inspection EVAP Leak Check Module Inspection.
Is it in good condition?
YES
Replace ECM and recheck DTC. Service and Repair
NO
Replace EVAP leak check module. Service and Repair
