1993 Saab 9000

VEHICLE DESCRIPTION: PASSENGER VEHICLES. MOISTURE CAN ENTER THE AIR BAG INFLATABLE RESTRAINT ELECTRONIC CONTROL MODULE (ECM) AND CAUSE CORROSION ON PORTIONS OF THE ECM PRINTER CIRCUIT BOARDS.

RiskTHIS CORROSION CAN POSSIBLY CREATE OPEN CONNECTIONS IN CIRCUITS WHICH CONTROL THE RESTRAINT DEPLOYMENT, POSSIBLY CAUSING INADVERTENT AIR BAG DEPLOYMENT.

FixDEALERS WILL INSPECT THE EXTERIOR OF THE ECM. IF THERE IS NO INDICATION OF MOISTURE, A COVER WILL BE INSTALLED OVER THE ECM. IF THERE IS INDICATION OF MOISTURE, THE DEALER WILL REPLACE THE ECM AND INSTALL A COVER OVER THE NEW ECM.

MOISTURE CAN FOLLOW THE ELECTRICAL HARNESS AND ENTER THE PRESSURE SWITCH CONNECTOR CAUSING CORROSION AND MALFUNCTION OF THE SWITCH.

RiskTHE CORROSION CAUSES A DETERIORATION OF THE ELECTRICALSWITCH CONNECTION AND CAN RESULT IN FALSE ILLUMINATION OF ABS AND/OR THE BRAKE WARNING LIGHTS AND/OR THE LOSS OF POWER ASSISTANCE BECAUSE OF NO HYDRAULIC PUMPOPERATION. LOSS OF POWER ASSIST INCREASES THE DRIVER'S BRAKE PEDAL EFFORT REQUIRED FOR STOPPING WHICH CAN RESULT IN EXTENDED BRAKING DISTANCES.

FixDEALERS WILL INSPECT THE ELECTRICAL CONNECTIONS TO THE ABS PRESSURE SWITCH TERMINALS FOR CORROSION AND INSTALL A SHRINK HOSE TO THE WIRING HARNESS TO AVOID MOISTURE ENTERING THE CONNECTION. PRESSURE SWITCHES WITH CORRODED CONNECTORS WILL BE REPLACED.

DURING LOW ENERGY FRONTAL IMPACT COLLISIONS, THE FRONT CROSSMEMBER CAN CONTACT THE METAL TUBING PORTION OF THE COOLER HOSE ASSEMBLY; AND/OR THE HOSE ASSEMBLY CAN BREAK AND LEAK OIL ONTO THE HOT EXHAUST MANIFOLD OR THE TURBOCHARGER.

RiskOIL LEAKING ON THESE HOT ENGINE SURFACES CAN IGNITE AND CAUSE A VEHICULAR FIRE.

FixDEALERS WILL INSTALL A PROTECTIVE COVER WHICH WILL PROTECT THE COOLER AND HOSES FROM OTHER STRUCTURAL COMPONENTS IN LOW ENERGY FRONT IMPACTS.

A NUMBER OF BRAKE LIGHT SWITCHES HAVE AN OVAL-SHAPED PISTON WHICH CAN GET STUCK UNDER CERTAIN CONDITIONS. OTHER SWITCHES WERE MOUNTED SO THAT BOTH LOCKING TABS ARE NOT COMPLETELY ENGAGED IN THE MOUNTING BRACKET. IF ONE SIDE IS NOT ENGAGED, THE SWITCH IS MISALIGNED WITH THE PEDAL MECHANISM AND CAN BIND THE PISTON MOVEMENT, WHICH CAN CAUSE THE BRAKE LIGHT SWITCH TO STICK IN THE "OFF" OR "ON" POSITION.

RiskTHIS RESULTS IN EITHER THE BRAKE LIGHTS REMAINING ON CONSTANTLY OR THE BRAKE LIGHTS NOT ILLUMINATING WHEN THE BRAKES ARE APPLIED. THIS RESULTS IN INACCURATE SIGNALS OF BRAKE OPERATION TO OTHER VEHICLE OPERATORS, AND COULD RESULT IN AN ACCIDENT.

FixDEALERS WILL INSPECT BRAKE LIGHT SWITCHES. FOR VEHICLES WITH THE OVAL-SHAPED PISTON AND FOR VEHICLES WITH MISALIGNED BRAKE LIGHT SWITCHES, THE BRAKE LIGHT SWITCH WILL BE REPLACED.

THE FUEL FILLER AND TANK VENTILATION HOSES MAY DEVELOP CRACKS UNDER THE SECURING HOSE CLAMPS, RESULTING IN FUEL LEAKAGE.

RiskFUEL LEAKS MAY RESULT IN A FIRE IF AN IGNITION SOURCEIS PRESENT.

FixTHE FUEL FILLER AND FUEL VENTILATION HOSES WILL BE REPLACED WITH NEW HOSES. THE FIVE SECURING HOSE CLAMPS WILL BE REPLACED BY A NEW TYPE WITH A SHIELD THAT PREVENTS DAMAGE TO THE HOSE WHEN TIGHTENED.
