********************************************************************* THIS BULLETIN CANCELS AND SUPERCEDES CORPORATE BULLETIN #73-90-12. PLEASE DISCARD CORPORATE BULLETIN #73-90-12 (SECTION 9 - ACCESSORIES). **********************************************************************

********************************************************************** IMPORTANT:

GM OF CANADA DEALERS AND NAES DEALERS ARE NOT AUTHORIZED TO UTILIZE THIS SERVICE BULLETIN. ********************************************************************

NEVER CONSIDER INSTALLING AN AIR BAG ON-OFF SWITCH UNLESS THE FOLLOWING CONDITIONS ARE MET:

1. THE CUSTOMER PRESENTS A LETTER FROM NHTSA AUTHORIZING THE INSTALLATION OF THE AIR BAG ON-OFF SWITCH.

2. THE DEALERSHIP GIVES THE CUSTOMER A COPY OF THE "NOTICE TO GM OWNERS ABOUT AIR BAG ON-OFF SWITCHES".

3. THE CUSTOMER STILL WANTS THE AIR BAG ON-OFF SWITCH INSTALLED.

THIS BULLETIN INCLUDES INFORMATION REGARDING SWITCHES TO TURN OFF AND ON FRONTAL AIR BAGS, ADDITIONAL SWITCH/DISPLAY LIGHT DIAGNOSIS, SWITCH INSTALLATION KIT CONTENT DESCRIPTIONS AND ORDERING DIRECTIONS FOR SPECIAL PARTS (IF REQUIRED).

THE NATIONAL HIGHWAY TRAFFIC AND SAFETY ADMINISTRATION (NHTSA) RECENTLY ANNOUNCED A NEW REGULATION ABOUT AIR BAGS. THE NEW REGULATION INCLUDES PROCEDURES THAT WILL PERMIT THE INSTALLATION OF AIR BAG ON-OFF SWITCHES FOR THE FEW CUSTOMERS WHO, IN NHTSA'S OPINION, FIT THE CRITERIA FOR SWITCHES.

#### IMPORTANT:

DUE TO THE NEW REGULATION, DEALERS SHOULD NO LONGER USE THE INFORMATION ON AIR BAG DISCONNECTION (CORPORATE BULLETIN # 73-90-12, DATED JUNE, 1997). INSTEAD, USE THE INFORMATION INCLUDED WITH THIS BULLETIN.

THE SWITCH INSTALLATION KIT CONTAINS THE NECESSARY COMPONENTS (SWITCH, BRACKET, ATTACHING HARDWARE, DISPLAY LIGHT, APPLIQUE SHEET FOR SWITCH AND LIGHT, TIE STRAPS AND INSTRUCTION SHEETS) FOR SYSTEM OPERATION. SOME KITS ALSO INCLUDE A REPLACEMENT SAFETY BELT FOR CERTAIN VEHICLES THAT ARE DESIGNED WITH SPECIFIC "FORCE LIMITING" SAFETY BELT SYSTEMS. SPECIAL OWNERS MANUAL INSERTS ARE INCLUDED IN THE INSTALLATION KIT FOR SYSTEM OPERATION REVIEW BY THE OWNER.

ADDITIONAL EQUIPMENT SUCH AS A 12 VOLT TEST LAMP AND THE J38125-B (-A OR -500 WILL ALSO APPLY) TERMINAL REPAIR KIT, ARE REQUIRED TO COMPLETE THE SWITCH KIT INSTALLATION. IN SOME CASES, SCAN TOOLS (TECH II OR EQUIVALENT) MAY BE REQUIRED TO REPROGRAM CERTAIN CONTROL MODULES.

THE COST OF THE SWITCH KIT AND LABOR TO INSTALL THE SWITCH KIT ARE THE RESPONSIBILITY OF THE CUSTOMER. SUGGESTED TIMES FOR INSTALLATION ARE INCLUDED AT THE END OF THIS BULLETIN (SEE ATTACHED).

#### IMPORTANT:

IN RARE INSTANCES, THE INSTALLATION OF SWITCH(ES) MAY TURN ON THE VEHICLE AIR BAG WARNING LIGHT. THIS CONDITION MAY EXIST DUE TO THE ADDITIONAL RESISTANCE OF THE SWITCH AND HARNESS WHEN ADDED TO THE SIR SYSTEM. IN THESE RARE INSTANCES, A "SPECIAL SERVICE ONLY" DIAGNOSTIC ENERGY RESERVE MODULE (DERM) OR SENSING AND DIAGNOSTIC MODULE (SDM) WILL BE MADE AVAILABLE TO THE OWNER FROM GMSPO AT NO CHARGE FOR THE PARTS OR LABOR. PRIOR TO ORDERING AND/OR INSTALLING A SWITCH KIT, THE CUSTOMER SHOULD BE ADVISED THAT THIS POTENTIAL DOES EXIST, AND CAN BE RESOLVED BY ONE OF THE FOLLOWING OPTIONS:

IF THE LIGHT DOES COME ON AFTER SWITCH INSTALLATION (AND PROPER INSTALLATION AND CONNECTIONS HAVE BEEN VERIFIED), ADVISE THE CUSTOMER THAT THE LIGHT HAS COME ON AND THAT THE VEHICLE:

A. MAY BE DRIVEN WITH THE LIGHT ON UNTIL THE SPECIAL DERM OR SDM IS AVAILABLE. THE SWITCH PORTION TO TURN OFF THE AIR BAG WILL STILL FUNCTION PROPERLY, BUT THE WARNING LIGHT WILL BE ON UNTIL THE ADDITIONAL PART CAN BE OBTAINED. WHEN THE DERM OR SDM IS AVAILABLE, THE CUSTOMER SHOULD RETURN TO HAVE THE PART INSTALLED (AT NO COST TO THE CUSTOMER) OR

B. MAY HAVE THE EXISTING AIR BAG SYSTEM RECONNECTED AND LEAVE THE SWITCH (INOPERATIVE) IN THE VEHICLE UNTIL THE ADDITIONAL PART CAN BE OBTAINED. WHEN THE DERM OR SDM IS AVAILABLE, THE CUSTOMER SHOULD RETURN TO HAVE THE PART INSTALLED (AT NO COST TO THE CUSTOMER).

THE STANDARD SIR SYSTEM DIAGNOSIS CAN BE MADE BY DISCONNECTING THE SWITCH FROM THE SIR WIRING HARNESS AND FOLLOWING THE DIRECTIONS FOR SIR SYSTEM DIAGNOSIS FOUND IN THE APPROPRIATE SERVICE MANUAL.

A DESCRIPTION OF THE MAJOR COMPONENTS OF THE INSTALLATION KIT IS AS FOLLOWS:

SWITCHES

ONE SWITCH KIT WILL BE REQUIRED FOR EACH AIR BAG (DRIVER OR PASSENGER) AND WILL BE IGNITION KEY OPERATED. WHEN THE SWITCH IS IN THE "OFF" POSITION, THE AIR BAG WILL REMAIN "OFF" UNTIL THE SWITCH IS TURNED TO THE "ON" POSITION. TURNING THE SWITCH TO THE "ON" POSITION WILL ALLOW THE AIR BAG TO FUNCTION.

THE RECOMMENDED LOCATIONS FOR THE SWITCHES ON MOST VEHICLES IS IN THE INSTRUMENT PANEL GLOVE COMPARTMENT (CENTER CONSOLE IF VEHICLE HAS NO GLOVE COMPARTMENT) OR, IN THE CASE OF SOME VANS, IN THE CENTER STOWAGE COMPARTMENT (SEE THE RECOMMENDED LOCATION ILLUSTRATIONS THAT ARE PROVIDED WITH EACH SWITCH KIT).

#### IMPORTANT:

SWITCHES OR DISPLAY LIGHT INDICATORS MUST NOT BE PLACED ON ANY INSTRUMENT PANEL SURFACES DIRECTLY IN FRONT OF THE DRIVER'S OR PASSENGER'S LEG OR KNEE AREAS.

DISPLAY LIGHT

EACH SWITCH REQUIRES A DISPLAY LIGHT TO INDICATE THE "OFF" STATUS OF THE AIR BAG. EACH DISPLAY LIGHT INCLUDES A HARNESS TO BE CONNECTED TO THE SWITCH HARNESS. THE RECOMMENDED MOUNTING LOCATIONS FOR THE DISPLAY LIGHTS VARY, BUT ARE TYPICALLY LOCATED AT THE CENTER FRONT EDGE OF THE ROOF HEADLINER (OR WINDSHIELD GARNISH MOLDING) ABOVE THE REAR VIEW MIRROR (SEE THE RECOMMENDED LOCATION ILLUSTRATIONS PROVIDED WITH EACH SWITCH KIT).

#### IMPORTANT:

WHEN INSTALLED, DRIVER AND/OR PASSENGER DISPLAY LIGHT(S) MUST BE VISIBLE BY ALL FRONT SEAT OCCUPANTS.

#### IMPORTANT:

SWITCHES OR DISPLAY LIGHT INDICATORS MUST NOT BE PLACED ON ANY INSTRUMENT PANEL SURFACES DIRECTLY IN FRONT OF THE DRIVER'S OR PASSENGER'S LEG OR KNEE AREAS.

WIRING CONNECTIONS

IN GENERAL TERMS, THE SWITCH WILL BE CONNECTED "IN SERIES" WITH THE APPROPRIATE AIR BAG (AT THE SERVICE DISCONNECT) AND WILL REQUIRE ADDITIONAL CONNECTION OF A FEED WIRE TO AN IGNITION FED CIRCUIT AND A GROUND WIRE TO THE BODY TO COMPLETE THE CIRCUIT FOR THE DISPLAY LIGHT INDICATOR.

DIAGNOSTICS FOR THE SWITCH AND DISPLAY LIGHT ARE INCLUDED WITH THIS BULLETIN (SEE ATTACHED).

AS ALWAYS, THE TECHNICIAN SHOULD MAKE SURE TO REVIEW THE WIRING HARNESS ROUTING AND INSTALLATION FOR PINCHING, RUBBING AND CHAFING TO BRACKETS, BRACES (ETC.) AND TAKE APPROPRIATE ACTIONS TO PROTECT THE WIRING FROM THOSE POTENTIAL CONDITIONS.

PARTS INFORMATION

ORDER THE APPROPRIATE INSTALLATION KIT(S) (PASSENGER, DRIVER, OR BOTH) FROM GMSPO. A PARTS BULLETIN CONTAINING THE SWITCH KIT PART NUMBERS WILL BE DISTRIBUTED. PARTS ARE EXPECTED TO BE AVAILABLE ON JANUARY 19, 1998.

IF SPECIAL DERMS OR SDMS ARE REQUIRED TO RESOLVE A "WARNING LIGHT ON" CONDITION, ORDER THE PART FROM GMSPO IN THE NORMAL MANNER. A PARTS BULLETIN CONTAINING THE SPECIAL PART NUMBERS WILL BE DISTRIBUTED AT A LATER DATE.

#### IMPORTANT:

1995-98 G (AURORA AND RIVIERA) AND 1997-98 Y (CORVETTE) SWITCH KITS INCLUDE REPLACEMENT SAFETY BELTS. THESE BELTS MUST REPLACE THE ORIGINAL SAFETY BELTS WHEN INSTALLING A SWITCH KIT. AURORA AND RIVIERA MODELS BUILT ON OR AFTER JANUARY 1, 1998 WILL INCLUDE "DEPOWERED" AIR BAGS, AND THE SAFETY BELTS ON THESE VEHICLES WILL NOT BE INCLUDED IN SWITCH KITS AND MUST NOT BE CHANGED. THE 1997-98 CORVETTE MODELS WILL REQUIRE SAFETY BELT CHANGES REGARDLESS OF BUILD DATES. THE BELTS WILL BE REPLACED AT NO CHARGE FOR THE PARTS OR THE LABOR.

WARRANTY INFORMATION

SWITCH KITS AND INSTALLATION ARE NOT CONSIDERED A WARRANTY REPAIR. PARTS AND LABOR CHARGES (EXCEPT FOR SPECIAL DERM OR SDM, AND REPLACEMENT SAFETY BELT INSTALLATION IF REQUIRED) ARE THE RESPONSIBILITY OF THE CUSTOMER. IF SPECIAL DERMS OR SDMS ARE REQUIRED TO RESOLVE A "WARNING LIGHT ON" CONDITION, USE THE EXISTING LABOR OPERATION AND TIME ALLOWANCES WITH THE SPECIAL CUSTOMER AND FAILURE CODES WHEN SUBMITTING CLAIMS:

DERMS - USE OPERATION C8815, CUSTOMER COMPLAINT CODE WK AND FAILURE CODE 93.

THE COST OF THE BELT IS INCLUDED IN THE KIT PRICE.
