high/erratic idle and/or the MIL light on. In some cases, vacuum leak noise may be heard as well. There may be poor contact or loss of contact at various main ground points or electrical connections. Power steering pressure switch may be shorted with debris. Inlet manifold gasket may be leaking. Broadcast code and calibration part number may need to be updated. To correct this condition, follow the procedures outlined in this bulletin to determine proper diagnosing, inspection and correction of ground contact points for proper electrical contact, power steering pressure switch cleaning or replacement and power steering system flush, replacement of inlet manifold gasket, and/or PCM reprogramming. SERVICE PROCEDURE Please refer to the appropriate workshop manual for the correct diagnosing procedure and/or follow the service procedures outlined in this bulletin for the vehicle being serviced. 1. Inspect main ground points (refer to SB99-04-S001 for more information). P6 ground point-body [on the passenger side of engine compartment, between the battery and cruise control actuator (if equipped)]. (Figure Fig. 1 ) P10 ground point-engine (at the alternator bracket). (Figure Fig. 2 ) The 1998, 1999 or 2000 Rodeo/Amigo Electrical Troubleshooting Manual can assist in locating the vehicle ground distribution (i.e., ground contact points). Perform a voltage drop test at the main ground points. If the voltage drop test fails, then inspect and clean both the bolt and

IMPORTANT: The important statement at the beginning of the “Ignition Lock Cylinder removal procedure on page 188 in the 2000/2001 Saturn S-Series Body/Electrical Volume II Service Manual is incorrect. Please cross out the important on that page and write in the following important statement. IMPORTANT: When replacing the ignition lock cylinder only, the passlock relearn procedure is not required. 1. Disconnect negative battery cable. 2. Remove lock cylinder bezel from steering column shroud by carefully prying with a thin bladed screwdriver. 3. Remove shroud fasteners and remove steering column upper and lower shroud panels. 4. Insert key into ignition lock cylinder and rotate to RUN position. If ignition lock cylinder can be rotated to RUN position, continue to step 30. ^ If ignition lock cylinder cannot be rotated to RUN position, continue with next step.

Vehicles equipped with engine or transmission computers may require a relearn procedure after vehicle battery is disconnected. Many vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When vehicle battery is disconnected, this memory is lost. The computer will use default data until new data from each key start is stored. As computer memorizes vehicle operation for each new key start, driveability is restored. Vehicle computers may memorize vehicles operation patterns for 40 of more key starts. Customers often complain of driveability problems during relearn stage because vehicle acts differently then before being serviced. Depending on type and make of vehicle and how it is equipped, the following complaints (driveability problems) may exist: Harsh Or Poor Shift Quality Rough Or Unstable Idle Hesitation Or Stumble Rich Or Lean Running Poor Fuel Mileage These symptoms and complaints should disappear after a number of drive cycles have been memorized. To reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle should be road tested.

MIL ILLUMINATION WITH P0171, P1170, LACK OF POWER, HESITATION APPLICABLE MODEL(S)/VINs All 1999-2000 Protege 1.6L with VINs lower than JM1 BJ222* *0 300996. DESCRIPTION Some vehicles may exhibit MIL illumination with any of the following symptoms: DTC P0171, DTC P1170, Lack of power, Hesitation, Unstable idle. These conditions may be caused by contamination of the mass air flow sensor wires. Customers having this concern should have their vehicle repaired using the following procedure. REPAIR PROCEDURE 1. Verify customer concern. 2. Record DTC and Freeze Frame data. 3. Inspect intake system for vacuum leaks. 4. Identify production date on MAF sensor. – If MAF sensor has a production date before 07B27 (July 27, 2000), proceed to STEP 5. – If MAF sensor has a production date on or after 07B27 (July 27, 2000), this Service Bulletin does not apply. Refer to Workshop Manual for further diagnostic procedures. 5. Clean surface surrounding MAF sensor. 6. Replace MAF sensor. Note: Make sure 0-ring is correctly positioned on replacement MAF sensor before installation. Caution: ^ Do not allow water to enter MAF sensor connector. ^ Handle replacement MAF sensor with care. 7. Inspect air cleaner and correct any unfiltered air leaks: ^ Improperly positioned air cleaner element and/or deformed seal. ^ Broken tabs, cracks and/or deformities of the air cleaner. 8. Disconnect negative battery cable or pull INJ fuse to erase and reset KAM (Keep Alive Memory). 9. Verify repair.
