SELF-DIAGNOSTIC SYSTEM
SAS unit will only display one code at a time. SAS unit will always display highest priority code first. After
repairing system, perform SYSTEM OPERATION CHECK
. If AIR BAG warning light is still flashing
during SYSTEM OPERATION CHECK, record code displayed. Repair system as necessary.
Retrieving & Clearing Codes
If codes are stored, AIR BAG warning light will flash or remain on when ignition is turned on. Codes are
automatically cleared when fault is corrected.
AIR BAG Warning Light Flashes
AIR BAG warning light indicates fault codes by flashing. Count the number of flashes between pauses to
determine code. See AIR BAG CODES
table. Codes are prioritized. If 2 or more faults are present, SAS unit
will display highest priority code first. After identifying code, go to appropriate code test.
AIR BAG Warning Light Remains On
Illumination of AIR BAG warning light continuously when ignition is turned on indicates a Code 0 (zero). See

1. Check WIPER fuse (20-amp) in passenger compartment fuse block. Check AD FAN (additional fan) fuse
(20-amp) in engine compartment fuse block. If fuses are okay, go to next step. If either fuse is blown,
check for shorted wiring harness before replacing fuse.
2. Operate engine at idle. Turn A/C and blower on. Using voltmeter, backprobe Black/Red wire terminal of
compressor clutch connector. If battery voltage exists, replace compressor clutch. If battery voltage is not
present, go to next step.
3. Ensure engine is running. Ensure A/C and blower are on. Using a voltmeter, backprobe Blue/Yellow wire
terminal of the A/C relay connector. If battery voltage exists, go to next step. If battery voltage does not
exist, repair open Blue/Yellow wire between AD FAN fuse and A/C relay.
4. Backprobe Blue wire terminal of A/C relay connector. If battery voltage exists, go to next step. If battery
voltage is not present, repair open Blue wire between WIPER fuse and A/C relay.
5. Backprobe Black/Red wire terminal of A/C relay connector. If battery voltage exists, repair open
Black/Red wire between A/C relay and compressor clutch. If battery voltage is not present, go to next
step.
6. Backprobe Blue/Black wire terminal of A/C relay connector. If voltage is Zero volts, replace A/C relay. I
f
voltage is not Zero volts, repair open Blue/Black wire between A/C relay and PCM. If wire is okay, check
PCM operation.
CONDENSER (ADDITIONAL) FAN CIRCUIT
1. Check ENGINE fuse (30-amp) in passenger compartment fuse block. Check AD FAN fuse (20-amp) in
engine compartment fuse block. If fuses are okay, go to next step. If either fuse is blown, check for
shorted wiring harness before replacing fuse.
2. Start engine. Turn A/C and blower switches on. Using voltmeter, backprobe Black/Yellow wire terminal
of condenser fan motor. If battery voltage exists, go to next step. If battery voltage is not present, go to
step 4).
3. Turn ignition switch off. Disconnect condenser fan connector. Using ohmmeter, check continuity
between Black wire of condenser fan connector and ground. If continuity exists, replace condenser fan. If
continuity is not present, repair open Black wire between condenser fan and ground.
4. Turn ignition on. Ensure A/C and blower switches are on. Using voltmeter, backprobe Black/White wire
terminal of condenser fan relay connector. If battery voltage exists, go to next step. If battery voltage is
not present, repair open Black/White wire between ENGINE fuse and condenser fan relay.
5. Backprobe Blue/Yellow wire terminal of condenser fan relay connector. If battery voltage exists, go to
next step. If battery voltage is not present, repair open Blue/Yellow wire between AD FAN fuse and
condenser fan relay.
6. Backprobe Black/Yellow wire terminal of condenser fan relay connector. If battery voltage exists, repair
open Black/Yellow wire between condenser fan relay and condenser fan. If battery voltage is not present,
go to next step.
7. Backprobe Blue/White wire terminal of condenser fan relay connector. If battery voltage exists, repair
Blue/White wire between condenser fan relay and PCM. If wire is okay, check PCM operation. If battery
voltage is not present, replace condenser fan relay.

FUEL SYSTEM SERVICE WARNING:When battery is disconnected, vehicles equipped with computers may
lose memory data. When battery power is restored, driveability problems
may exist on some vehicles. These vehicles may require a relearn
procedure. See COMPUTER RELEARN PROCEDURES article in GENERAL
INFORMATION section.
CAUTION: Before replacing a blown fuse, remove ignition key, turn off all lights and
accessories to avoid damaging the electrical system. Be sure to use fuse
with the correct indicated amperage rating. The use of an incorrect
amperage rating fuse may result in a dangerous electrical system
overload.
CAUTION: Indicator will cause a squealing or scraping noise, warning that brake
pads need replacement.
CAUTION: Continued operation of vehicle with a severe malfunction could cause
converter to overheat, resulting in possible damage to converter and
vehicle.
CAUTION: Any modification to the exhaust system on turbo models, which reduces
exhaust backpressure, will lead to lean fuel mixtures and excessive spark
advance. This could cause serious engine damage.
WARNING:Many solid state electrical components can be damaged by static
electricity (ESD). Some will display a warning label, but many will not.
Discharge personal static electricity by touching a metal ground point on
the vehicle prior to servicing any ESD sensitive component.
CAUTION: Never use non-detergent or straight mineral oil.
