instrument panel.
AC061 Overheating warning light.Activating this actuates the engine overheating warning light
on the instrument panel.
AC068Injection fault warning light.Activating this actuates the injection fault warning light on
the instrument panel.
AC099Deactivation of electrical
consumersThis activation only deactivates the preheating function.
AC100End deactivation of electrical
consumersActivating this enables preheating to be authorised after the
injection computer has been programmed or reprogrammed
(see Replacement of components).
