Accessory Socket Test/Replacement
Front Accessory Socket:
1. Remove the center dashboard lower cover (see sec-
tion 20).
Disconnect the 2P connector from the front accessory
socket.
Inspect the connector terminals to be sure they are
all making good contact.
2.
lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
lf the terminals look OK, go to step 4.
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.
