DIAGNOSTIC MONITORING OF TANK LEAKAGE (DMTL) - NAS ONLY
| Item Number | Description |
|---|---|
| 1 | DMTL pump |
| 2 | Charcoal canister atmospheric vent pipe |
| 3 | DMTL pump intake filter |
The DMTL system periodically checks the evaporative system and the fuel tank for leaks when the ignition is switched off. The DMTL pump is connected to the atmospheric vent of the charcoal canister and incorporates a positive temperature coefficient (PTC) heating element a normally open valve and a reference orifice. The DMTL pump is only operated when the ignition is switched off and is controlled by the engine control module (ECM). The engine control module (ECM) also monitors the electric air pump operation and the normally open valve for faults. To check the fuel tank and EVAP system for leaks the engine control module (ECM) operates the DMTL pump and monitors the current draw. This is compared to a referenced figure established from the current draw when air is pumped through the reference orifice. Refer to Evaporative Emissions .
DIAGNOSTICS
The diagnostic socket is located in the fascia, in the driver's stowage tray. The socket is secured in the fascia panel and is protected by a hinged cover.
The engine control module (ECM) stores faults as diagnostic trouble code (DTC), referred to as 'P' codes. The 'P' codes are defined by on-board diagnostic (OBD) legislation and, together with their associated environmental and freeze frame data, can be read using a third party scan tool or T4. T4 can also read real time data from each sensor, the adaptive values currently being employed and the current fueling, ignition and idle settings.
