For 1990-2009 cars

### Seed and Key Method

• | This method takes about 10 minutes for programming.

• | A programming system is required (refer to Saturn Service Stall System or Tech 2 User Guide).

• | A Scan tool is required.

### Auto Learn Method (Optional)

| Important: If no components are replaced, the 30 minute autolearn can always be used.

• | This method is usable if the Passlock sensor was the ONLY required system part change. BCM or PCM replacement requires use of Sand K Method.

• | This method takes about 30 minutes.

• | A Scan tool is not required.

Both methods are included in the flow chart on the next page.

The following table shows when the relearn procedure needs to be performed.

#### Relearn Procedure

Part Replaced | Action Required
--- | ---
Passlock sensor only replaced | BCM needs relearn procedure
BCM replaced only | PCM needs relearn procedure
PCM replaced only | None required, PCM instantly relearns
BCM and PCM replaced | None required, BCM and PCM instantly relearn
Do not use a BCM from another vehicle to aid in diagnosis. BCMs are not interchangeable after they have been installed.
