Code B0098:04 Description

When the ignition switch is turned to ON, the Inflatable Restraint Sensing and Diagnostic Module (SDM) will perform a turn-on test to diagnose critical malfunctions within the inflatable restraint sensing and the diagnostic module itself. The inflatable restraint sensing and diagnostic module continuously check the disable switch position switch and circuit defect by letting the regular voltage flow through the disable switch circuit and verifying the current. The Diagnostic Trouble Code (DTC) will be set when the inflatable restraint sensing and diagnostic module detects an open/high resistance in the passenger air bag disable switch signal circuit or the passenger air bag disable switch ground circuit.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
