| DTC Strategy |
- ELCM pressure signal monitoring
|
- EVAP. Emission System failure
- ELCM failure
|
| Enable Condition |
- Vehicle stop (VSS 0mph/0 kph)
- Engine stop (Engine 0 RPM)
- Ignition key off
- No related failures
- No refueling during diagnosis
- Ambient air pressure is greater than 75 kpa
- ECM soaking time (engine stop) is more than 5 hours
- Ambient air temp. (AAT) is greater than 4°C (39.2°F)
- Fuel level in the tank is less than 85%
- Battery voltage is between 10V and 16V
|
| Threshold Value |
- Deviation between ELCM pressure and intake manifolder is greater than -20 kpa. (signal high)
- Deviation between ELCM pressure and intake manifolder is less than 20 kpa. (signal low)
