Operation CHARM: Car repair manuals for everyone.

Passlock 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.




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

IMPORTANT: Do not use a BCM from another vehicle to aid in diagnosis. BCMs are not interchangeable after they have been installed.
