Circuit Description
WARNING: This page is about a different variant/trim than selected.
The VCM contains a memory area where it stores certain data it needs to save when ignition is turned off. This area is called Keep Alive Memory. This test monitors VCM's keep alive memory for a loss or unintended change of data. If such a condition occurs, DTC will set.
DTC will set if data from the memory location does not match test data which was saved to memory.
