PINPOINT TEST A : SMART KEY NOT FOUND - REFER TO HANDBOOK TEST
CONDITIONS DETAILS/RESULTS/ACTIONS A1: IGNITION MODE FAILS TO SWITCH ON NOTES:
In normal operation, pressing the start button for one second will cause the vehicle to enter the ignition mode. If the
procedures below are followed the engine should crank
For automatic transmission vehicles, ensure the brake pedal is depressed and the park or neutral selected 1 Ensure the smart Key is within the cabin area. Check the smart key is not close to any electrical devices e.g. Smart phones, laptops, laptop cases, games consoles and game console bags, briefcases, metal
objects etc. All can affect the system performance and may block its communication with the vehicle. If
the smart key battery low warning message has been displayed it is likely that the smart key battery has
insufficient charge. Refer to section 'Back Up Start' for 10MY onwards Has the vehicle started? Yes

Component Description DIAGNOSTIC MODULE - TANK LEAKAGE PUMP (NAS ONLY)
The DMTL (diagnostic module - tank leakage) pump periodically checks the EVAP system and the fuel tank for leaks when the ignition is switched off. The DMTL system comprises the previously described components of the EVAP system with the following additional components; a DMTL pump and a DMTL filter.
The DMTL pump is connected to the atmospheric vent of the EVAP canister and incorporates an electric air pump, a PTC (positive temperature coefficient) heating element, a normally open change-over valve and a reference orifice. The DMTL pump
is only operated when the ignition is switched off and is controlled by the ECM. The ECM also monitors the electric air pump operation and the change-over valve for faults.
The DMTL filter protects the pump from dust being drawn into the system when the pump is being operated. The filter is
located on the fuel filler head and is connected to the DMTL pump by a vapor pipe.
The DMTL test is performed after the engine has stopped following a run of 10 minutes or more, providing that the vehicle fuel
tank is between 15 and 85% full, the ambient temperature is above 0 °C (32 °F) and less than 40 °C (104 °F) and the vehicle
was not started for at least 180 minutes prior to this run.
The DMTL pump is driven to pressurize the fuel tank and the current is measured with the change-over valve in different
states.
A comparison of the current draw in each state indicates the degree of any leak, and the ECM then sets the appropriate DTC (diagnostic trouble code).

For a detailed description of the Evaporative Emissions system, refer to the relevant Description and Operation section in the

Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:
If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into
account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
