10.6.2 Fault code history

Up to 50 of the most recently occurred fault codes will be stored in a log along with the hour meter reading when the fault occurred. When the fault code log is displayed, it shows the fault codes in chronological order with the newest code first.

Carry out the following to display the fault code log:

•Ensure the battery is connected.

•Ensure the truck is switched off. Press on the keypad.

•Press and hold horn button S18 for at least 1 second, enter a valid

PIN-code and then press on the keypad.

•Hold S18 depressed until “E” is displayed, then release S18. Fig. 10

Fault symbol lights.

The most recently occurred error will be displayed. The display will alternate between the fault code and the hour meter reading when the fault occurred. If the fault code log contains more than one fault code, these can be displayed by repeatedly operating the speed control L1.

10.6.3 List of fault codes

NOTE!

The text “Restart the truck!” in the following tables always means switching the truck off completely by removing the battery connector [X1], reconnecting and then switching the truck on again.
