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.

Engine Oil Pressure
Indicator System
Description
NOTE: Reter to page 23-144 tor the circuit diagram otthe engine oil pressure indicator flasher, snd to page
23-148 lor the input test of the flasher circuit.
The low engine oil pressure indicator tight works in twoways. lt will flash continuously following a momentaryloss of oil pressure, or it will go on and stay on with acomplete loss of oil pressure.
When the engine first starts, before oil Dressure risesabove 29.4 kP8 10.3 kgf/cmr, 4.3 psi), current flowsthrough the low engine oil pressure indicator light andthe oil pressure switch to ground. This tests the circuit.
Wilh the engine running, voltage is applied ro the ftash-er circuit of the integrated control unit. With normal oilpressure, the oil pressure switch is open and the low en-gine oil pressure indicator light does not operate. lf theoil pressure switch closes momentarily (more than O.5secondsl, but then opens again, terminal "yEL/RED,'will
sense ground through the switch. The integrated con-trol unit willthen provide and remove ground for th€ lowengine oil pressure indicator light through terminal"YEL/RED". The light will flash on and olf until the igni-tion switch is turned to "OFF".
lf engine oil pressure falls below 29.4 kPa (O.3 kgJ/cmr,4.3 psi) and does not increase, the oil pressure switchwillstsy closed. The low engine oilpressure indicator lightwill go on and stav on.
NOTE; Refer to page 23-122lot the engine oil pressure
switch test.
Lights-on Reminder
System
Description
Chime Test
Remove the dashboard lower cover and knee bolster
{see page 23-70).
Disconnect the 2-P connector t.om the dashboardwire hamess.
Test the chime by connecting battery power to the"A" te.minal and ground to the "B" terminal, andcycling the power on-off repestedly.
lf the chime fails to sound every time power is cy-cled, reDlace it.
NOTE: Refer to page 23-145 tor a diagram of the lights-
on reminder circuit, and to page 23-149 for the input
tests of the circuit.
When the ignition key is turned to OFF 8nd removed. withthe lights on, voltage is apptied to the reminder circuitin the integrat€d control unit. When you open the driver,sdoor, the circuit senses ground through the closed doorswitch.
With voltage at the "H" terminal, ground at the"GRN/BLU2" terminal and no voltage at the ,,F,' termi-nal, the chime sounds to remind the driver to turn oJf thelights.
