Tests AA: DTC B2987 - Deployable Steering Column Circuit Resistance Low On Squib

PINPOINT TEST AA: DTC B2987 - DEPLOYABLE STEERING COLUMN CIRCUIT RESISTANCE LOW ON SQUIB

Lamp Fault Codes (LFCs)
The following LFC indicate the specific fault associated with DTC B2987:







Normal Operation
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.

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, flash LFC 12-10 on the air bag warning indicator.

- DTC B2987 Deployable Steering Column Circuit Resistance Low on Squib - If the RCM detects low resistance on the deployable steering column circuits, it will set this DTC.

This pinpoint test is intended to diagnose the following:
- Wiring, terminal or connectors
- Deployable steering column
- RCM
