|What Does the B1418 Code Mean?

The Restraint Control Module (RCM) monitors the passenger front door and LH C-pillar side impact sensors and circuits for the following faults: Open circuit, Short to voltage, Short to ground, Faulted passenger front door side impact sensor, Faulted LH C-pillar side impact sensor. If a fault is detected, the RCM stores DTC B1418 in memory and sends a message to the Instrument Panel Cluster (IPC) to illuminate the airbag warning indicator. The RCM communicates with each impact sensor. If the RCM is unable to communicate with the sensor, a Diagnostic Trouble Code (DTC) is stored in memory. A Continuous Memory Diagnostic Trouble Code (CMDTC) no operation can be set by a short to voltage on the return circuit of the impact sensor.

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.
