Normal Operation
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
As part of the supplemental restraint system (SRS), the vehicle is equipped a deployable steering column. The restraints control module (RCM) will deploy (collapse) the steering column during a frontal collision when seat position information and other parameters reach predetermined limits. Refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) .
The RCM checks the deployable steering column circuits for faults. If the RCM detects an open circuit, it will store DTC B2984 in memory and flash LFC 12-7 on the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Steering column
- RCM
