| Elise OBDII Error Codes |
The following was posted on the Elise Talk forum. www.elisetalk.com
Malfunction Indicator Lamp The engine Malfunction Indicator Lamp (MIL) is provided to warn the driver that the engine management system has detected a fault which may result in increased noxious emissions from the exhaust. In order to minimise emissions and potential engine damage, various operational limitations may automatically be applied.
i) If the MIL lights continuously whilst driving, immediately reduce speed and adopt a moderate driving style. Seek dealer advice without delay and avoid all unnecessary journeys.
ii) If the MIL flashes, an engine misfire has been detected which is likely to cause overheat damage to the catalytic converter. Slow down immediately and be prepared to stop.
Note:
The following is based upon the Lotus Service Manual regarding engine codes. A "Lotus" tool is recommended to read the code(s), it has been established if a "standard" code reader will work.

When applicable, reference may be made under the 'Notes' heading to a page in the Toyota service manual. This information should be used only for diagnosis and connection detail of the sensor. The Elise/Exige uses a Lotus ECU, the connections for which may be found in circuit diagrams in Section MP. Diagnostic Trouble Codes should be read using a Lotus Scan tool T000T1418F.
EMP.2 - ‘LOTUS SCAN’ DIAGNOSTIC TOOL
In order to provide for communication with the engine management system electronic control module, a
hand held electronic scanner ‘Lotus Scan’ (part number T000T1418F), may be plugged into a special 16
terminal harness connector socket, known as a Data Link Connector (DLC), located at the front of the
passenger footwell. Note that this tool may also be used on previous Elise models (excluding Exige,
340R and 160 models).
Amongst the operations available using the ‘Lotus Scan’ tool are:
