a Overcharging will raiso ths tempelature ot th€ electrolyte. This may force electrolyte to splay out of the battery venta.
Follow lhe chargor manutacturer's instluctions and chargo tho battory at a prop61 rate.
NOTE: The original radio has a coded theft protection circuit. lt service to the car requires any of the lollowing, be sure
to get the customer's code number before- disconnecting the battery.- removing No. 32 (7.5 Al fuse from the under-hood fuse/relay box- removing the radio,
After service, reconnect power to the radio and turn it on. When the word "CODE" is displayed, enter the customer's
s-digir code to restore radio operation,
Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. It you don'r have one of these com-puterized testers, follow this conventional test procedure:
To get accurate results, the temperature ot the electrolyte must be between TOoF l21ool and IOOoF {38oCl.
lf the case is cracked or the posts are loose,
replace the battery.
lf the indicator shows low electrolvte, add
distilled water it oossible.

NOTE:
a See section I 1 if the malfunction indicator lamD (MlL)
blinks.
a Pertorm an input test for the ignition control module
(lCM) after finishing the fundamental tests for the ig-
nition system and the fuel and emissions systems.
a The tachometer should operate normally.
1. Remove the distributor cap, the distributor rotor, and
the leak cover.
2. Disconnect the BLK/YEL, WHT/BLU, YEL/GRN, and
BLU wires from the lCM.
3. Turn the ignition switch ON. Check for voltage be-
tween the BLK/YEL wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check the BLK^/EL
wire between the ignition switch and the lCM.
a lf there is battery voltage, go to step 4.

4.Turn the ignition switch ON. Check for voltage be-
tween the WHT/BLU wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check:- lgnition coil- WHT/BLU wire between the ignition coil and
the ICM
a lf there is battery voltage. go to step 5.
Check the YEL/GRN wire between the ECM and the

Check the BLU wi.e between the tachometer and the
rcM.
It all tests are normal, replace the lCM.

Check for continuity again, this time with th€ engine
runnrng.
a lf there is continuity, go to step 4,
a lf there is no continuity, the switch is OK.
Make sure engine oil level is OK, then check engin€

Add less than 8.2 t (2.2 U.S.Gal, 1.8 lmp.Gal) of fuel
and turn the ignition switch ON (ll). The low fuel in-
dicator light should com€ on within lour minutes,
a lf the light does not come on, remove the access
Danel and disconnect the 3-P connector from the
fuel gauge sending unit, Connect the A
(BLKMHT) terminal to the C (BLU/WHT) termi-
nal with a iumper wir€.- lf the light comes on, the problem is either the
sending unit or its ground.- lf the light does not come on, the problem is
an open in the BLU/WHT wire to the gauge as-
