Occupant Classification Module: Notes

WARNING: This page is about a different car, the 2004 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Both Air Bag Control Module (ACM) and Occupant Classification Module (OCM) store calibration data, which they transmit to one another when one is replaced. If both are replaced at same time, an irreversible trouble code will be set in both modules. If both modules require replacement, replace one. Then perform verification test before replacing the other.
