gle of the vehicle by way of signals to the headlight range control
unit -J431- .

in the following instances:
♦ Vehicle level senders installed are not of type specified in this
workshop manual
♦ Vehicle level senders have mechanical fault
♦ Vehicle suspension has been modified (e.g. lowered)
Note
If the values of the vehicle level senders are outside the specified
tolerance, basic headlight setting cannot be carried out.
