Hi John,

Titus and Trev are right. Try the sensor first they do give problems, usually causing the machine to drive in slow mode.
The display is a seven segment display. The designations are as follows the top segment is "a" and moving clockwise each segment thereafter follows the alphabet, i.e. b, c etc. If there is a fault look at this display and make a note of which segments are lit. I should have list of the fault codes relating to the display.

Hi John, Yes, I have the list with a description for the codes on the display, it's only a paper copy. Do you have a fax no. and I'll send, otherwise I'll have to scan and email which will take awhile.
