Leak Detector: Testing and Inspection

EVAP Leak Check Module Circuit Inspection

NOTE:

For operation of EVAP leak check module, refer to Description and Operation EVAP Leak Check System Description.

EVAP Leak Check Pressure Sensor Circuit Check

1) With ignition mode of keyless push start system in "OFF", connect SUZUKI scan tool to DLC.
2) Push engine switch to change ignition mode of keyless push start system to "ON".
3) Select "Data List" mode on SUZUKI scan tool.
4) Check that displayed barometric pressure is specified value referring to "EVAP Leak Check Pressure Sensor (Combine with BARO Sensor) On-Vehicle Inspection" under EVAP Leak Check Module Inspection EVAP Leak Check Module Inspection.

If barometric pressure is within specified value, EVAP leak check pressure sensor and its circuit are in good condition.

If barometric pressure is out of specification, check EVAP leak check pressure sensor, wire harness and connections.

EVAP Leak Detection Pump Circuit Check

1) With ignition mode of keyless push start system in "OFF", connect SUZUKI scan tool to DLC.
2) Push engine switch to change ignition mode of keyless push start system to "ON".
3) Select "Active Test" mode on SUZUKI scan tool.
4) Use SUZUKI can tool to check that operating sound of EVAP leak detection pump is heard only when pump is switched to "Operate".

If operating sound of EVAP leak detection pump is heard, EVAP leak detection pump and its circuit are in good condition.

If operating sound of EVAP leak detection pump is not heard, check EVAP leak detection pump, wire harness and connections.






EVAP Canister Vent Valve Circuit Check

1) With ignition mode of keyless push start system in "OFF", connect SUZUKI scan tool to DLC (1).
Special Tool

(A): SUZUKI scan tool (SUZUKI-SDT)





2) Push engine switch to change ignition mode of keyless push start system to "ON".
3) Select "Active Test" mode on SUZUKI scan tool.
4) Use SUZUKI scan tool to check that operating sound of EVAP canister vent valve (1) is heard only when EVAP canister vent valve is switched between "Open" and "Close".

If operating sound of EVAP canister vent valve is heard, EVAP canister vent valve and its circuit are in good condition. If operating sound of EVAP canister vent valve is not heard, check EVAP canister vent valve, wire harness and connections.
