Removal/lnstallation
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (241 before performing repairs or ser-
vice.
Removal:
1. Make sure you have the anti-theft code for the radio,
then write down the frequencies for the radio's pre-
set buttons (with anti-theft feature).
2. Disconnect the battery negative cable, then discon-
nect the positive cable, and wait at least three min-
utes.
3. Remove the driver's dashboard lower cover and the
knee bolster (see section 20).
4. Remove the two mounting nuts, and pull the under-
dash fuse/relay box out from under the dash
Disconnect the connectors from the under-dash
fuse/relay box (see section 24 for the SRS main har-
ness connector), and take out the under-dash fuse/
relay oox.
Installation:
1. Connect the connectors to the under-dash fuse/
relay box (see section 24 for the SRS main harness
connector), then install the under-dash lusehelay
box in the reverse order of removal.
2. lnstall the knee bolster and the driver's dashboard
lower cover (see section 20).
3. Connect the battery positive cable, then connect the
negative cable.
4. Enter the anti-theft code for the radio, then enter the
customer's radio station presets (with anti-thett fea-
ture).
5. Confirm that all systems work properly

Test
@M. Battery fluid (eleqtrolyte) contains sulturic acid. lt may couse sevore burns if it gets on your skin or in your eyes. Wearprotective clothing and a fac6 shield.- lf elestrolyte gets on your skin o. clothos, rinse it otf with wator imm€diately.- lf €leqtrolyte gets in your eyes. tlush it out by splashing water in your syes for at least 15 minutes; call a physicianimmediately.
. A battery gives off hydrogon gas. lf ignited, the hydrogen will €xplode and could crack the battery case and splatt€racid on you. Kgop sparks. flamss, and cigarettes away from the batt€ry,. Overcharging will raise the tomperatute of the electrolyte. This may torcs electrolyto to spray out of the battEry vents,Follow the charger manutacturer's instructions, and charge the battery at a proper ral€,
Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. lf you don't have one of tnese comput-erized testers, follow this conventional test procedure:
To get accurate results, the temperature ofthe electrolyte must be between 70.F (21.c) and loo"F (38"c).

lf the indicator shows low electrolyte, add distilled
water if possible.
