LRemove the driver's dashboard lower cover and
knee bolster (see section 20).
Disconnect the connectors from the daytime run-
ning lights control unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded. repair
them as necessary, and recheck the system.
lf the terminals look OK, make the following
input tests at the connector,- lf any test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the control unit
must be faulty; replace it.
