| • | 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.
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. | |
