# ENHANCED EMISSION INSPECTION MAINTENANCE PROGRAM

#### SUBJECT: Enhanced Emission Inspection Maintenance Program

#### TO: Saturn Fixed Operation Managers

The new Enhanced Emission Inspection Maintenance (I/M) program has begun in various areas of the country.

This "enhanced" I/M test (also referred to as the IM240 test) actually consists of three specific tests (and any additional tests that individual states may require). These IM240 tests are:

1. The IM240 Test - This test consists of a transient dynamometer test event which will be conducted at centralized (state owned) test facilities. The exhaust gasses measured during the IM240 test event are: HC, CO, and NOx. This test event is much more comprehensive than current I/M tests.

2. The Purge Flow Test - This test measures the flow of unburned hydrocarbons through the purge solenoid during the IM240 test. The objective is to determine that sufficient flow is present under the proper operating conditions.

3. The Evaporative System Pressure Test - The objective of this test is to evaluate the integrity of the fuel tank vapor recovery system. It is conducted by pressurizing the fuel tank and fuel vapor lines. Pressure is then monitored to assure the system is leak-free.

Attached to this bulletin is a list of thosc states which will participate in the Enhanced Emission Inspection Maintenance 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 clected to implement a statewide program. To ascertain if your retail facility is affected by this program, refer to the attached list which details those areas affected by the Enhanced Emission Inspection Maintenance program; along with the projected start dates as declared by the state. Check with your local environmental agency to obtain more detailed information.

To assist in the proper repair of vehicles that may not meet the requirements of the state test, Saturn has developed an I/M240 Diagnostic Service Manual supplement that you should have already received.

Also, a mandatory one-day technician training class has been developed for the retail facilities in and around states or metropolitan areas that are affected by I/M testing laws. A bulletin with more training detail, including the roll-out schedule, will be supplied in the near future. The up coming Fixed Operations Managers (FOM) Service Consultants, Continuous Learning Seminar will also introduce this subject along with a proposed IM240 write-up procedure to assist in the proper diagnosis of these vehicles.

Currently, Saturn is not requiring the purchase of any additional tools or equipment to diagnose or repair Saturn vehicles. However, if you feel you do need additional tools and equipment to properly repair your used vehicles, we would recommend the following be purchased from GM Dealer Equipment (GMDE) by calling 1 (800) 468-6657.

TOOL NO. DESCRIPTION -------- ----------- 108-39982 Five Gas Analyzer 108-41417 Propane Enrichment Tool 108-41413 Evaporative Pressure/Purge Diagnostic Station 108-41418 Purge Flow Meter 108-41415 Fuel System Pressure Adapter 108-41416 Ultrasonic Leak Detector

Saturn believes that many products currently on the market are either incapable of performing the required diagnostics and repair function, or include expensive features that may not be required and therefore, recommends that you do not purchase emission - related equipment other than the items listed above.

#### IMPORTANT: The Implementation Dates on the following charts are subject to change. To verify the Implementation Date, check with the Coordinator for your area.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
