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 with 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 detect low resistance on either circuit, it will store DTC B2987 in memory and flash LFC 12-10 on the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- Wiring, terminal or connectors
- Deployable steering column
- RCM
