1CHECK FUSE.
1) Turn the ignition switch to OFF.
2) Remove the fuse (No. 31).
Is the fuse blown out? Replace the fuse
(No. 31). If the
replaced fuse has
blown out easily,
repair the short cir-
cuit of harness
between fuse (No.

ness for open or
shorted circuit
between body inte-
grated unit and
fuse.
3CHECK POOR CONTACT OF CONNECTOR.Is there poor contact in body
integrated unit connector?
Repair the poor
contact of connec-
tor.
Go to step 4.
4CHECK BODY INTEGRATED UNIT HAR-
NESS.
1) Connect all the connectors.
2) Perform the clear memory mode.
3) Read DTC.
Is DTC displayed? Replace the body
integrated unit.
