Abstract

A method of carrying out fault detection in a vehicle transmission (2,4) provided with a computer- controlled gear changing system in which there is a display unit (48) and a plurality of switches (23-29,36,38,40,42) and solenoid valves (15-21) for performing gear changing. The first operation step is started by manual actuation of a test program switch (14) in the vehicle which triggers a program stored in the control unit (7) for automatic functional testing of the display unit (48). and that one or more further operation steps are triggered by the switch (14) being subjected to further manual actuation, under each of said further operation steps the test program determines how functional testing of the switches (23-29,36,38,40,42) and/or solenoid valves (15-21) shall be performed so that for a given fault, predetermined information in the test program is displayed by the display unit (48). <IMAGE>
