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.
Frequently Asked Questions about B1B8D RAM Code
1. What does the OBDII code B1B8D mean for a RAM vehicle?
The B1B8D code indicates a "Driver Seat Track Position Sensor Circuit Low," meaning the sensor that monitors the driver's seat position has an electrical issue, typically low voltage.
2. What are common symptoms of the B1B8D code?
Symptoms may include an illuminated airbag warning light, malfunctioning seat memory settings, or the driver's seat position sensor not working as intended.
