Alternator Replacement
NOTE: The original radio has a coded theft protection
circuit. Be sure to get the customer's code number before
- disconnecting the battery.- removing the No. 32 {7.5 A) fuse from the under-hood
fuse/relay box.- removing the radio.
After service, reconnect powet to the radio and turn it on.
When the word "CODE" is displayed, enler the cus-
tomer's 5-digit code to restore radio operation.
1 . Disconnect the ground cable from the battery nega-
tive (- ) terminal.
2. Disconnect the alternator connector from the al-
rernaror.

Alternator Belt Inspection and Adjustment
Deflection Method:
Apply a force of 100 N (1o kgt, 22 lbJ) and measure the
deflection between the alternator and the crankshatt
pulley.
Detlsction:9-11 mm (0.35-O.43 inl
NOTE; On a brand-new belt {one that has be€n run
for less than five minutes), the deJlection should be
6-8 mm 1O.23-O.32 in) wh€n first measured. lf
the belt is worn or damaged, replace it.

lf adiustment is nocessarY:
1. Loosen the alternator adjusting nut and mounting
nur.
2. Move the alternator to obtain the proper belt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the deflection ot the belt.
NOTE: lt necessary, adiust the P/S pump belt (see
section 17) and A/C compressor belt lsee section
22t.

Boh Tsnsion Gaug6 Mothod:
Foltowing the gauge manuJacturer's instructions, attach
the belt tension gauge to the belt and measure the
tension.
Tension: 340-49O N (35-50 kgl, 77-110 lbfl
NOTE: On a brand-new belt (one that has been run
for less than tive minutes), tension should be
690-880 N (70-90 kgt, 154- 198 lbJ) when tirst
measured. lf the belt is worn or damaged, replace it.
lf adi$tmsnt is nscaasary:
1. Loosen the alternator adiusting nut and mounting
nut.
2. Move ths ahernator to obtain the proper bslt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the tension of the belt,
NOTE: lf necessary, adjust the P/S pump belt (see
section 17) and A/C compressor belt (see section
22t.

Supplemental Restraint System (SRSI
Troubleshooting
Self-diagnosis Function
The SRS unit includes a self-diagnosis function. lf there
is a failure in the sensors. SRS unit, inflator, or their cir-
cuits, the SRS indicator light in the gauge sssembly
comes ON.
As a system check, the SRS indicator light also comes
on when the ignition is first turned ON to the (ll) posi-
tion. lf the light goes off after approximately six sec-
onds, the system is OK.
lf the SRS indicator lighr remains on (or fails to come on
in the system check mode), one of the SRS components
(or the wiring/connectors inbetween) is laulty
Troubleshooting Precautions
a Always use the test harness. Do not use test probes
directly on component connector terminals or wires;
you may damage them or the SRS unit.
a When connecting any of the test harnesses to the
system, push the connectors straight-in; do not bend
the connector terminals,
. Before disconnecting any part of the SRS wire har-
ness, connect the shon connector (RED) on the driv-
er's airbag. On cars equipped with a front passen-
ger's airbag, connect short connectors on the driver's
airbag and the front passenger's airbag.
SRS Indicator Light Troubleshooting
Possiblo conditions:
1. SRS indicator light does not come on at all - see
page 23-278.
2. SRS indicator light stays on constantly - see page
23-242.
3. SRS indicator light comes on in combination with a
failure of another electrical system (charging sys-
tem light). Check for damage/corrosion at the
under-dash tuse/relay box connector.
NOTE:
. Before starting the applicable troubleshooting. check
the condition of all SRS connectors and ground
points.
. lf the fault is not found after completing the applica-
ble troubleshooting, substitute a known-good SRS
unit and check whether the indicator light goes off.
