0 r).
There should be batterY voltage
. If there is no voltage, check for:
- blown No. 17 (7 5 A) fuse in the under-dash
tuse/relay box- an open in the BLK'/YEL wire.
o lf there is battery voltage, go to step 2.
2. Check for continuity between the No 4 (BLK) termi-
nal and body ground.
There should be continuity.
. lf there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G551).
Left mirror inoporalive:
connect the No. 2 {BLK/YEL) terminal of the 10P connec-
tor to the No. 3 (YEURED) terminal and the No 5 (or No
6) terminal to body ground with jumper wires The left
mirror should tilt down (or swing left) when the ignition
switch is turned ON (ll)
. lf the mirror does not tilt down (or does not swing left),
remove the left door panel. and check for an open in
the BLU/WHT (or BLU/BLK) wire between the left
power mirror and the switch
- lf the wire is OK. check the left power mirror actua-
tor.
lf the mirror neither tilts down nor swings left. repair
the YEURED wire.
lf the mirror operates properly, check the mirror switch'
Right mirror inoperative:
Connect the No. 2 (BLK /EL) terminal of the 10P connector
to the No. 3 (YEURED) terminal and the No. 9 (or No 8)
terminal to body ground with jumper wires The right mir-
ror should tilt down (or swing left) when the ignition
switch is turned ON (ll).
. lf the mirror does not tilt down (or does not swlng
left), remove the right door panel. and check for an
open in the GRN/WHT (or YEUBLK) wire between the
right power mirror and the switch.
- lf the wire is OK, check the right power marror actu-
ator.
. lf the mirror neither tilts down nor swings left. repair
the YEURED wire
. lf the mirror operates properly, check the mirror
switch.

SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRSsection (24) before performing repairs or service.
1. Remove the driver's dashboard lower cover and knee bolster (see section 20).
2. Disconnect the l4P 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, or corroded, repair them as necessary, and recheck the system.lf the terminals look OK, make the following inpul tests at the connecror.- 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.
