File In Section: 6E - Engine Fuel & Emission

Bulletin No. 43-65-07

Date: December, 1994

Subject:
Enhanced Emission Inspection Maintenance Program - Implementation Plan

Models:
1995 and Prior Passenger Cars and Trucks

The new Enhanced Emission Inspection Maintenance program is scheduled to begin in various areas of the country beginning January, 1995. A previous bulletin (Engine Fuel & Emission, # 436505) was issued in April, 1994, which described the structure of this new emission program, refer to it for background on the IM240 program.

IM240 Areas:

Illustrated are those states which will participate in the Enhanced Emission program as well as a state contact and phone number. In most cases, the test program will be limited to major-urban areas, although some states have elected to implement a statewide program. To ascertain if your facility is affected by this program, refer to the attached list which details those areas affected by the lM240 program along with the projected start dates as declared by each state. Check with your local environmental agency to obtain more detailed information.

5 Gas Analyzer:

Based on our experience, correction of vehicle failures identified by the Enhanced Emission program will require specialized equipment and diagnostic techniques. General Motors Service Technology Group has successfully developed and validated an approach to diagnose and repair vehicles tested under this Enhanced Emission program. As a result, dealerships located within an Enhanced Emission area will receive special equipment and diagnostic information. This essential equipment and associated costs consists of a 5 gas Exhaust Gas Analyzer at $4195.00, an Evaporative Pressure/Purge Diagnostic Station at $1500.00, and a Propane Enrichment tool at $110.00.

Included in this bulletin is information from Kent-Moore concerning the exhaust gas analyzer, financing terms, early delivery program, and additional units. They will be sent in a timely fashion relative to the program's implementation date in your area. Those dealerships located outside an

Enhanced Emission area may purchase this equipment (at essential tool prices) if they wish to take advantage of this new opportunity created by the Enhanced Emission Test program by contacting Kent-Moore (1-800-345-2233).

If your dealership is located within an Enhanced Emission area, and you currently own an exhaust gas analyzer, you may qualify for a waiver for this equipment. Waiver eligibility is dependent upon the features of your gas analyzer. The criteria for waiver of the gas analyzer is as follows, the gas analyzer must possess the following:

^ HC, CO2 Measurability.
^ HC range 5000 PPM min and CO2 range 10% min.
^ Memory capability (60 SEC min) of (HC/CO2).
^ Memory display-printing capability or CRT
^ Ability to operate on vehicles with exhaust diffusers (trucks).

If your analyzer meets the above criteria (refer to your equipment owner's manual), you may contact Kent Moore at 1-800-345-2233 to request a waiver for the exhaust gas analyzer, but you must do so 30 days prior to your state's implementation date. Please be prepared to report Brand, Model, and Serial Number of your unit. A waiver will also be available for the propane enrichment tool which was essential approximately 15 years ago, if you still possess it. No waiver is available for the Evaporative Pressure/Purge Diagnostic Station due to the unique nature of this tool. This Diagnostic Station includes all necessary gas cap adapters, purge system gauges, and leak detection equipment. Since it will be used on upcoming OBDII applications as well as IM240, it will be shipped to the balance of the GM dealerships coincident with the 1996 model announcement.

To assure that your dealership is adequately prepared for the Enhanced Emission program, you will want to have your technicians trained on this subject. The GM Training Center will offer a course beginning in December, 1994, titled Vehicle Emissions, Enhanced Testing and Repair, Course # 16004.10. Having competent, trained technicians will give your service department a competitive edge, by offering your customers a dependable repair facility which can fix vehicles right the first time. Refer to your local GM Training Center for details on this course.
