FAULT CODES
The warning lamp will illuminate when the ignition is switched on, but as soon as the engine is started the warning lamp will go out. If the warning lamp stays on or comes on while the engine is running, then the ecu has detected a fault. If the ecu detects a serious fault then the ecu will then switch to an emergency programme which will allow the vehicle to be driven to a garage, so that the fault can be cured.
To activate the fault codes connect a wire to A and B of the diagnostic plug (10 pin version), then the fault codes will be displayed from the fault code light as flashes, eg. fault code 12 displays as one flash, pause, then two flashes.
To erase the fault code, turn the ignition on/off for 25 times, if this is unsuccessful then disconnect the battery earth lead for at least one minute. The disadvantage for removing the earth lead is that it will erase the memory from other electronic units, eg. security coded radio.
