l. Bemove the driver's dashboard lower cover and the knee bolster (see section 20).
2, Disconnect the 5P connector from the control unit.
3. 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 recheck the system.

ACCESSORYSOCKET
Turn the ignition switch to ACC (l), and check for
voltage between the No. 1 and No. 2 terminals.
. There should be battery voltage.
. lf there is no battery voltage, check for:- blown No.27 (10 A) fuse in the under-dash
fuse/relay box.- poor ground (G401, G402).- an open in the wire.
