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

PROGRAM STATUS

THE PURPOSE OF THIS BULLETIN IS TO PROVIDE INFORMATION ON THE CURRENT STATUS OF THE ENHANCED IM PROGRAMS IN VARIOUS STATES. FOR BACKGROUND INFORMATION ON THE ENHANCED IM PROGRAM, REFER TO BULLETINS 43-65-05, 43-65-07, AND 43-65-10. WHILE SOME STATES HAVE ALREADY STARTED ENHANCED IM TESTING, MANY STATES ARE PLANNING TO IMPLEMENT THEIR ENHANCED IM PROGRAM IN 1996. PROGRAM IMPLEMENTATION DELAYS HAVE RESULTED DUE TO DEBATE OVER THE TYPE OF PROGRAM TO IMPLEMENT. SOME STATES ARE STILL PLANNING TO IMPLEMENT IM240 TEST PROGRAMS, WHILE OTHERS ARE GRAVITATING TOWARD STEADY SPEED LOADED-MODE TESTS. THE LOGISTICS OF EACH TEST PROGRAM (CENTRALIZED VS. DECENTRALIZED) ARE ALSO BEING EVALUATED.

EQUIPMENT SHIPMENT PROCEDURE

THE SERVICE TECHNOLOGY GROUP WORKS DIRECTLY WITH STATE IM ADMINISTRATORS REGARDING THEIR ENHANCED IM PROGRAM STATUS. STG WILL CLOSELY TRACK THE PROGRESS MADE BY EACH STATE TOWARD IMPLEMENTING THEIR IM PROGRAM. WHEN A STATE APPROACHES AND CONFIRMS THEIR IMPLEMENTATION DATE, STEPS WILL BE TAKEN BY STG AND KENT MOORE TO PRODUCE AND SHIP THE ESSENTIAL EQUIPMENT. IF THE STATE DECIDES TO DELAY THEIR PROGRAM, THE SHIPMENT OF EQUIPMENT WILL ALSO BE DELAYED. USING THIS APPROACH MINIMIZES THE RISK OF PREMATURE SHIPMENT OF EQUIPMENT TO DEALERS. IN ISOLATED SITUATIONS WHERE A STATE HAS IMPLEMENTED AN IM PROGRAM AND LATER SUSPENDED IT, DEALERS ARE URGED TO RETAIN POSSESSION OF THE EQUIPMENT SINCE THE STATE WILL ULTIMATELY BE REQUIRED TO IMPLEMENT A REPLACEMENT IM PROGRAM. IT IS IMPORTANT TO UNDERSTAND THAT, WITH THE EXCEPTION OF THE BASIC IM IDLE TEST, ALL OTHER EMISSION TEST PROGRAMS UNDER CONSIDERATION WOULD REQUIRE THE USE OF THE ESSENTIAL EQUIPMENT FOR VEHICLE DIAGNOSIS. AND REMEMBER, THE EVAPORATIVE PRESSURE/PURGE DIAGNOSTIC STATION (J 41600) IS ESSENTIAL FOR THE OBDII PROGRAM AS WELL AS THE ENHANCED IM PROGRAM.

AN EQUIPMENT DECISION

AS EACH STATE APPROACHES THEIR IMPLEMENTATION DATE, YOU WILL BE CONTACTED BY KENT MOORE PERSONNEL TO DETERMINE IF YOU INTEND TO:

1.) UPDATE YOUR EXISTING ANALYZER*.

2.) PURCHASE NEW EQUIPMENT WITH REQUIRED CAPABILITIES* OR,

3.) ACCEPT 5 GAS ANALYZER PER THE ESSENTIAL TOOL PROGRAM.

*MUST MEET THE WAIVER CRITERIA (REFER TO BULLETIN 43-65-07 FOR WAIVER REQUIREMENTS).

IF YOU ELECT TO UPDATE YOUR CURRENT GAS ANALYZER, KENT MOORE HAS BEEN INSTRUCTED TO MAKE ARRANGEMENTS WITH THE APPROPRIATE MANUFACTURER TO INITIATE THE UPGRADE. IF YOU HAVE ANY QUESTIONS REGARDING THE 5 GAS ANALYZER OR WAIVER CRITERIA, CONTACT KENT MOORE ON 1-800-345-2233.
