Mark :

Hello, my name is XXXXX XXXXX I will try help you with this.

Mark :

Turn the ignition off connect the terminal marked TEN on the 17 pin connector to earth then have an LED tester and put this in to the terminal marked FEN and turn the ignition on. The circuit tester should start to flash and if memory serves me correctly the glow plug light will flash in the same pattern at the same time. These flashes are fault codes, when the LED tester flashes it should start with a long flash followed by one or several short flashes then another long flash then short flashes. The long flash is a separator for the numbers of the code, if you get 2 long flashes in a row this indicates a zero between them.

For example a long flash,another long flash followed by 5 short flashes then 2 long flashes would indicate a code of 0500 (vehicle speed sensor circuit fault). Or 2 long flashes followed by a short flash then 2 long flashes indicates 0100 (MAF circuit fault).

You may need a couple of attempts to interpret the flashes at first but the pattern should repeat, all the engine management codes on this vehicle should be 4 digits the first flash should be a long one.
