NOTE: Be careful not to damage the controller and the
instrument panel.
Remove the instrument panel from the dashboard
(see page 23-126).
Remove the dash lights brightness controller from
the dashboard, then disconnect the 3P connector.
Inspect the connector and socket terminals to be
sure they are all making good contact.
a lf the terminals are bent, loose or cortoded, repair
them as necessary, and recheck the system.
a It the terminals look OK, make the following in-
put tests at the connector.- lf any test indicates a problem, find and cor
rect the cause, then recheck the system.
It all the input tests prove OK, the dash lights
brightness controller must be faulty; replace it.
