Lotus Service Notes
Lotus TechCentre - 2008 model year
All USA market cars from '08 model year onwards, are required by legislation to use a CAN compliant on-
board diagnostic system. This has been commonised for all Elise/Exige models. The Lotus Scan 3 tool is
replaced by a 'stand alone' lap top PC loaded with 'Lotus TechCentre' software to allow the CAN based serial
data to be read.
Controller Area Network (CAN) is an electronic standard to allow high speed communication between
modules and controllers, via a serial data bus. The bus is a circuit linking the modules to the controller,
consisting of a pair of cables, twisted together to reduce electromagnetic interference, and carrying a square
wave voltage signal corresponding to '0's and '1's, coded in such a way as to identify and prioritise the indi-
vidual messages. On the Elise/Exige, CAN based systems for 2008 onwards include; engine management,
anti-lock braking and related features, tyre pressure monitoring and onboard diagnostics.
A Vehicle Communication Device (T000T1472F) introduced for the Europa model is used to connect the
vehicle to the laptop Lotus TechCentre. All system interrogation and diagnosis are carried out via the Lotus
TechCentre.
The minimum specification of the laptop computer for installation of the Lotus TechCentre is as follows:
- Processer 1.70 Ghz;
- 1 GB RAM;
- 40 GB HDD;
- CDRW DVD ROM;
- WIN XP PRO or VISTA;
- USB interface;
- Ethernet or Wireless LAN
Note that this laptop should be dedicated soley to the Lotus TechCentre, with no other software installed.
This diagnostic software is designed primarily for use by trained Lotus technicians, and is available as a CD
under part number T000T1510F (version 4) or later supercessions. A monthly (Lotus Dealers) or annual (non-
Lotus dealers) licence and support fee will also be levied, providing access to Lotus TechCentre Technical
Support phoneline on 0870 9493 668, and e-mail on lotus.support.uk@omitec.com
Also required is a unique 18 character licence/registration key without which Techcentre will not function.
This key is non transferable to other PC's.
