Known issues on the 2014 Express 2500. Fifteen complaints are on record for this model year, divided evenly at three each among the air bags, the fuel and propulsion system and the electrical system. An even split like that usually means unrelated individual faults rather than a shared cause. The restraint chapter gives the code-driven diagnostic sequence and the connector and resistance checks an air bag lamp calls for; the fuel chapters give delivery pressures and injection specifications by engine; and the wiring diagrams cover the circuits behind the remainder.
