PRODUCT RECALL CAMPAIGN

PRODUCT SAFETY CAMPAIGN

#### SUBJECT: 98032 - AIR BAG SENSING AND DIAGNOSTIC MODULE (SDM) SEALING FOR WATER INTRUSION

#### MODELS: 1995 CADILLAC CONCOURS, DEVILLE, ELDORADO, AND SEVILLE

THE HIGHWAY SAFETY ACT, AS AMENDED, PROVIDES THAT EACH VEHICLE WHICH IS SUBJECT TO A RECALL CAMPAIGN OF THIS TYPE MUST BE ADEQUATELY REPAIRED WITHIN A REASONABLE TIME AFTER THE CUSTOMER HAS TENDERED IT FOR REPAIR. A FAILURE TO REPAIR WITHIN SIXTY (60) DAYS AFTER TENDER OF A VEHICLE IS PRIMA FACIE EVIDENCE OF FAILURE TO REPAIR WITHIN A REASONABLE TIME.

IF THE CONDITION IS NOT ADEQUATELY REPAIRED WITHIN A REASONABLE TIME, THE CUSTOMER MAY BE ENTITLED TO AN IDENTICAL OR REASONABLY EQUIVALENT VEHICLE AT NO CHARGE OR TO A REFUND OF THE PURCHASE PRICE LESS A REASONABLE ALLOWANCE FOR DEPRECIATION.

TO AVOID HAVING TO PROVIDE THESE BURDENSOME REMEDIES, EVERY EFFORT MUST BE MADE TO PROMPTLY SCHEDULE AN APPOINTMENT WITH EACH CUSTOMER AND TO REPAIR THEIR VEHICLE AS SOON AS POSSIBLE. AS YOU WILL SEE IN READING THE ATTACHED COPY OF THE DIVISIONAL LETTER THAT IS BEING SENT TO CUSTOMERS, THE CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE APPROPRIATE CUSTOMER ASSISTANCE CENTER IF THEIR DEALER DOES NOT REMEDY THE CONDITION WITHIN FIVE (5) DAYS OF THE MUTUALLY AGREED UPON SERVICE DATE. IF THE CONDITION IS NOT REMEDIED WITHIN A REASONABLE TIME, THEY ARE INSTRUCTED ON HOW TO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION.

DEFECT INVOLVED

GENERAL MOTORS HAS DECIDED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN CERTAIN 1995 CADILLAC CONCOURS, DEVILLE, ELDORADO, AND SEVILLE MODEL VEHICLES. IF THE VEHICLE IS DRIVEN THROUGH DEEP STANDING WATER OR OTHERWISE ACCUMULATES A SUBSTANTIAL AMOUNT OF WATER OR FLUID ON THE CARPETING UNDER THE DRIVER'S SEAT, MOISTURE MAY ENTER THE AIR BAG SENSING AND DIAGNOSTIC MODULE (SDM). IF THE INTERIOR OF THE SDM IS EXPOSED TO WATER, ONE OR BOTH OF THE VEHICLE AIR BAGS MAY DEPLOY WITHOUT PRIOR WARNING. AIR BAGS DEPLOY WITH GREAT FORCE AND CAN SERIOUSLY INJURE ANYONE WHO IS TOO CLOSE TO THEM. TO REDUCE THE POSSIBILITY OF THIS CONDITION OCCURRING, DEALERS ARE TO CLEAN THE EXTERIOR CASE OF THE SDM AND APPLY POTTING COMPOUND (SPECIALIZED SEALER) TO THE SDM CASE AND ELECTRICAL CONNECTOR BODY.

VEHICLES INVOLVED

INVOLVED ARE ALL 1995 CADILLAC CONCOURS, DEVILLE, ELDORADO, AND SEVILLE MODEL VEHICLES BUILT WITHIN THE FOLLOWING VIN BREAKPOINTS:

IF POTTING COMPOUND IS NOT PRESENT, PROCEED TO STEP # 17 OF THIS SERVICE PROCEDURE.

FIGURE 5

#### NOTICE: THE AREAS TO BE SEALED MUST BE THOROUGHLY CLEANED WITH A SCOTCH BRITE PAD BEFORE APPLYING THE POTTING COMPOUND. FAILURE TO PROPERLY CLEAN AND PREPARE THE SURFACES TO BE SEALED MAY RESULT IN AN INEFFECTIVE SEAL, WHICH COULD ALLOW WATER TO ENTER THE SDM CASE. IF WATER ENTERS THE SDM CASE, AN UNWANTED AIR BAG DEPLOYMENT COULD OCCUR.

17. THOROUGHLY CLEAN THE EXTERIOR OF THE SDM CASE USING THE 3M SCOTCH BRITE PAD PROVIDED. PAY CAREFUL ATTENTION TO THE AREAS WHERE POTTING COMPOUND WILL BE APPLIED, SO THAT THE POTTING COMPOUND CAN BOND TO A CLEAN SURFACE. IF NECESSARY, CAREFULLY REMOVE ANY LIGHT OXIDATION/CORROSION FROM THE CASE. USING A CLEAN SHOP CLOTH, CAREFULLY REMOVE ANY CLEANING RESIDUE FROM THE SURFACE OF THE SDM CASE.

INSTALLATION OF THE SDM BACK INTO THE VEHICLE BEFORE THE POTTING COMPOUND HAS HAD ADEQUATE TIME TO SET UP MAY RESULT IN AN INEFFECTIVE SEAL, WHICH COULD ALLOW WATER TO ENTER THE SDM CASE. IF WATER ENTERS THE SDM CASE, AN UNWANTED AIR BAG DEPLOYMENT COULD OCCUR.

POSITION THE SDM SO THAT THE ELECTRICAL CONNECTOR IS FACING UP. CAREFULLY APPLY POTTING COMPOUND AROUND THE CONNECTOR BODY AS SHOWN IN FIGURE 5. ALLOW THE POTTING COMPOUND TO SET UP FOR 15 MINUTES BEFORE REPOSITIONING THE SDM FOR THE NEXT APPLICATION OF POTTING COMPOUND.

AFTER THE POTTING COMPOUND APPLIED AROUND THE CONNECTOR BODY HAS SET UP FOR 15 MINUTES, CAREFULLY APPLY POTTING COMPOUND TO THE FOUR (4) SCREWS ON THE SIDES (RIGHT, AND REAR) OF THE SDM, MAKING SURE THAT THE POTTING COMPOUND FULLY PENETRATES THE AREA AROUND THE BASE OF THE SCREWS.

POSITION THE SDM SO THAT THE BOTTOM IS FACING UP. CAREFULLY APPLY POTTING COMPOUND TO THE CASE JOINT, MAKING SURE THAT THE ENTIRE LENGTH OF THE JOINT IS SEALED. APPLY POTTING COMPOUND TO THE TWO (2) SCREW RECESSES IN THE BOTTOM OF THE CASE AS SHOWN IN FIGURE 5. APPLY SUFFICIENT POTTING COMPOUND TO THE SCREW CAVITIES TO FILL THEM, BUT DO NOT OVER FLOW ONTO THE BOTTOM OF THE CASE. ALLOW THE POTTING COMPOUND TO SET UP FOR 25 MINUTES BEFORE RE-INSTALLING THE SDM INTO THE VEHICLE.

IF ONLY ONE SDM IS BEING SEALED, IMMEDIATELY REMOVE AND DISCARD THE APPLICATOR TIP, AND SECURELY INSTALL THE CAP TO THE TUBE. EACH TUBE OF POTTING COMPOUND WILL SERVICE EIGHT VEHICLES; RETAIN UNUSED PORTION TO SERVICE FUTURE VEHICLES. ADDITIONAL APPLICATOR TIPS HAVE BEEN PROVIDED (8 TIPS PER TUBE OF POTTING COMPOUND) SO THAT IT IS NOT NECESSARY TO SAVE THE APPLICATOR TIP FOR RE- USE ON ANOTHER VEHICLE AT A LATER DATE.

#### NOTICE: THE POTTING COMPOUND WILL NOT BE FULLY CURED WHEN RE-INSTALLING THE SDM TO THE VEHICLE. USE CARE WHEN HANDLING THE SDM TO AVOID SMEARING/RUBBING THE POTTING COMPOUND.

FIGURE 5

#### NOTICE: THE AREAS TO BE SEALED MUST BE THOROUGHLY CLEANED WITH A SCOTCH BRITE PAD BEFORE APPLYING THE POTTING COMPOUND. FAILURE TO PROPERLY CLEAN AND PREPARE THE SURFACES TO BE SEALED MAY RESULT IN AN INEFFECTIVE SEAL, WHICH COULD ALLOW WATER TO ENTER THE SDM CASE. IF WATER ENTERS THE SDM CASE, AN UNWANTED AIR BAG DEPLOYMENT COULD OCCUR.

17. THOROUGHLY CLEAN THE EXTERIOR OF THE SDM CASE USING THE 3M SCOTCH BRITE PAD PROVIDED. PAY CAREFUL ATTENTION TO THE AREAS WHERE POTTING COMPOUND WILL BE APPLIED, SO THAT THE POTTING COMPOUND CAN BOND TO A CLEAN SURFACE. IF NECESSARY, CAREFULLY REMOVE ANY LIGHT OXIDATION/CORROSION FROM THE CASE. USING A CLEAN SHOP CLOTH, CAREFULLY REMOVE ANY CLEANING RESIDUE FROM THE SURFACE OF THE SDM CASE.

18. FOR CONTROLLED FLOW OF POTTING COMPOUND, CUT OFF THE TIP OF ONE OF THE APPLICATOR TIPS TO PROVIDE THE SMALLEST POSSIBLE OPENING (APPROXIMATELY 2MM INNER DIAMETER). CAREFULLY APPLY LOCTITE 5140 POTTING COMPOUND AS SHOWN IN FIGURE 5 PER THE FOLLOWING INSTRUCTIONS:

#### NOTICE: DO NOT ALLOW POTTING COMPOUND TO CONTACT THE PINS IN THE CONNECTOR BODY. ALSO, MAKE SURE THAT THE CPA/LOCKING MECHANISM IS CLEAR AND WILL FULLY ENGAGE THE HARNESS CONNECTOR WHEN RE-CONNECTING THE HARNESS TO THE SDM.

IT IS VERY IMPORTANT THAT THE POTTING COMPOUND BE ALLOWED TO SET UP FOR 15 MINUTES AFTER APPLICATION AROUND THE CONNECTOR BODY, AND FOR 25 MINUTES AFTER THE REMAINING APPLICATION. INSTALLATION OF THE SDM BACK INTO THE VEHICLE BEFORE THE POTTING COMPOUND HAS HAD ADEQUATE TIME TO SET UP MAY RESULT IN AN INEFFECTIVE SEAL, WHICH COULD ALLOW WATER TO ENTER THE SDM CASE. IF WATER ENTERS THE SDM CASE, AN UNWANTED AIR BAG DEPLOYMENT COULD OCCUR.

POSITION THE SDM SO THAT THE ELECTRICAL CONNECTOR IS FACING UP. CAREFULLY APPLY POTTING COMPOUND AROUND THE CONNECTOR BODY AS SHOWN IN FIGURE 5. ALLOW THE POTTING COMPOUND TO SET UP FOR 15 MINUTES BEFORE REPOSITIONING THE SDM FOR THE NEXT APPLICATION OF POTTING COMPOUND.

AFTER THE POTTING COMPOUND APPLIED AROUND THE CONNECTOR BODY HAS SET UP FOR 15 MINUTES, CAREFULLY APPLY POTTING COMPOUND TO THE FOUR (4) SCREWS ON THE SIDES (RIGHT, AND REAR) OF THE SDM, MAKING SURE THAT THE POTTING COMPOUND FULLY PENETRATES THE AREA AROUND THE BASE OF THE SCREWS.

POSITION THE SDM SO THAT THE BOTTOM IS FACING UP. CAREFULLY APPLY POTTING COMPOUND TO THE CASE JOINT, MAKING SURE THAT THE ENTIRE LENGTH OF THE JOINT IS SEALED. APPLY POTTING COMPOUND TO THE TWO (2) SCREW RECESSES IN THE BOTTOM OF THE CASE AS SHOWN IN FIGURE 5. APPLY SUFFICIENT POTTING COMPOUND TO THE SCREW CAVITIES TO FILL THEM, BUT DO NOT OVERFLOW ONTO THE BOTTOM OF THE CASE. ALLOW THE POTTING COMPOUND TO SET UP FOR 25 MINUTES BEFORE RE-INSTALLING THE SDM INTO THE VEHICLE.

IF ONLY ONE SDM IS BEING SEALED, IMMEDIATELY REMOVE AND DISCARD THE APPLICATOR TIP, AND SECURELY INSTALL THE CAP TO THE TUBE. EACH TUBE OF POTTING COMPOUND WILL SERVICE EIGHT VEHICLES; RETAIN UNUSED PORTION TO SERVICE FUTURE VEHICLES. ADDITIONAL APPLICATOR TIPS HAVE BEEN PROVIDED (8 TIPS PER TUBE OF POTTING COMPOUND) SO THAT IT IS NOT NECESSARY TO SAVE THE APPLICATOR TIP FOR RE-USE ON ANOTHER VEHICLE AT A LATER DATE.

#### NOTICE: THE POTTING COMPOUND WILL NOT BE FULLY CURED WHEN RE- INSTALLING THE SDM TO THE VEHICLE. USE CARE WHEN HANDLING THE SDM TO AVOID SMEARING/RUBBING THE POTTING COMPOUND.

19. WITH THE ARROW ON THE TOP OF THE SDM POINTING TOWARD THE FRONT OF THE VEHICLE, INSTALL THE MODULE TO THE FLOOR PAN. SEE FIGURE 4.

20. INSTALL THE SDM FASTENERS AND TIGHTEN TO 11 N M (98 LB. IN.).

21. RECONNECT THE ELECTRICAL CONNECTOR TO THE SDM AND INSTALL THE CONNECTOR POSITION ASSURANCE (CPA).

22. APPLY DOUBLE-SIDED TAPE TO THE CARPET AND SECURE CARPET IN PLACE OVER THE SDM.

23. REINSTALL THE SEAT IN THE VEHICLE AND ENGAGE THE FRONT RETAINING HOOKS INTO THE FLOOR PAN. SEE FIGURE 3.

24. TILT THE SEAT FORWARD AND CONNECT THE POWER SEAT ELECTRICAL CONNECTORS.

25. TILT THE SEAT REARWARD AND INSTALL THE TWO BOLTS THAT RETAIN THE REAR OF THE SEAT TO THE FLOOR PAN. TIGHTEN TO 32 N M (24 LB. FT.).

26. CHECK FOR PROPER OPERATION OF THE SEAT.

27. CONNECT THE YELLOW 2-WAY CONNECTOR AND CPA TO THE PASSENGER INFLATOR MODULE PIGTAIL THROUGH THE TRAP DOOR IN THE INSTRUMENT PANEL COMPARTMENT. SEE FIGURE 2.

28. CONNECT THE YELLOW 2-WAY CONNECTOR AND CPA TO THE YELLOW CONNECTOR AT THE BASE OF THE STEERING COLUMN. SEE FIGURE 1.

29. INSTALL THE LH SOUND INSULATOR.

30. INSTALL THE S.I.R. FUSE IN THE FUSE BLOCK.

31. TURN THE IGNITION SWITCH TO "ON" AND VERIFY THAT THE "AIR BAG" WARNING LAMP FLASHES SEVEN (7) TIMES AND THEN TURNS "OFF". IF IT DOES NOT OPERATE AS DESCRIBED, PERFORM THE S.I.R. DIAGNOSTIC SYSTEM CHECK AS DESCRIBED IN SECTION 9J OF THE APPROPRIATE SERVICE MANUAL.
