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.

Attached to this bulletin is a list of 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 IM240 program along with the projected

start dates as declared by each state. Check with your local environmental

agency to obtain more detailed information.

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.

Attached to 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:

o HC, CO2 Measurability.

o HC range 5000 ppm min and CO2 range 10% min.

o Memory capability (60 sec min) of (HC/CO2)

o Memory display-printing capability or CRT.

o 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,
