A/C & HEATER SERVICE PROCEDURES FOR 2002 Saturn SC Series AUTOMOBILES
Computer Relearn Procedures -> Saturn -> Auto Learn Method -> Crankshaft Learn Procedure -> Crankshaft Relearn Procedure -> Passlock Theft Deterrent Relearn Procedure -> PCM/ECM Learning Procedure -> Remote Keyless Entry Synchronization -> Seed & Key Method
Vehicle: 2002 Saturn SC Series 1.9 L4 GAS
Crankshaft Learn Procedure
The PCM uses crankshaft velocity calculations to determine engine misfire and to run misfire self-diagnostics. The PCM must know precisely the variability in crankshaft notches for this function. The PCM has a notch learn process that learns the variability between notches which must be reset if the crankshaft has been replaced. Using a suitable scan tool, the "Crankshaft Learn Procedure" can be set to "Relearn."
Crankshaft Relearn Procedure
Any time a PCM or crankshaft position sensor is replaced the PCM must relearn the crankshaft notches. ...

BRAKE SERVICE PROCEDURES FOR 2002 Saturn SC Series AUTOMOBILES
Power Brake Units -> Description -> AC-Delco Single Diaphragm Type -> AC-Delco Tandem Diaphragm Type -> Toyota/GM Single Diaphragm Type
Vehicle: 2002 Saturn SC Series 1.9 L4 GAS
AC-Delco Tandem Diaphragm Type
This unit utilizes a vacuum power chamber, consisting of a front and rear shell, housing divider, front and rear diaphragm, plate assemblies, hydraulic pushrod and a diaphragm return spring, Fig. .
In normal operating mode, with service brakes in released position, the booster operates with vacuum on both sides of its diaphragms. When brakes are applied, air at atmospheric pressure is admitted to one side of each diaphragm to provide power assist. When the service brake is released, atmospheric air is shut off from one side of each diaphragm. The air is ...
