FAULT-FINDING TABLE
NOTE: The faults described below ("warning light not working") give a summary of all the cases in which the warning light is not operating correctly: e.g. the warning light turns on to indicate a failure and this failure does not exist, or vice-versa, a function has been switched on and the warning light fails to show it, etc...
PRECAUTION!: The instrument cluster C10 cannot be overhauled. Therefore in the event of a failure, individual warning lights cannot be changed and the whole unit C10 must be replaced (the only exceptions are the high beam warning light and the cluster lighting lamp). Also in the case of an incorrect setting of one of the indicators, it is not possible to change the individual component (e.g. rev counter, fuel level gauge, etc.) and the whole instrument cluster unit C10 must be replaced.
