EVAP leak detection pump operation check
- Check operating sound of EVAP leak detection pump referring to "EVAP LEAK DETECTION PUMP CIRCUIT CHECK
" under EVAP Leak Check Module Circuit Inspection
.
Is operating sound heard? |
Go to Step 4. |
Go to Step 3. |

Detection pump circuit check
- Confirm that ignition mode of keyless push start system is "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 Ω
- 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? |
Go to Step 4. |
Repair or replace defective wire harness. |
