headlight switch off and the parking brake se1. lt should go off when you turn on the headlight switch and release the
parking brake. lf it comes on at any other time, do the control unit input test.

Inspect the connector and socket terminals to be sure they are all making good contact.
. lf the terminals are bent, loose orcorroded, repairthem as necessary, and recheckthe system.
' lf the terminals look OK, go to step 4.
