Apparently, NHTSA took issue with the positioning of the oil pan drain plug. The most common electromechanical sensor uses a steel ball that’s secured to the end of a tube with a magnet. When an air bag warning lamp pops on, most of the time you’ll retrieve a circuit DTC. If multiple fuses blow, your circuit is most likely shorted and will require additional service. He drove it into the shop and retrieved a DTC for high resistance in the driver’s air bag circuit. Current Chevy Trucks, SUV's, Crossovers & Vans, Sensing and diagnostic module (dealership-only tool). That's how sensitive the monitor is. Somehow, during the crash test the drain plug was a problem. Children are safer when properly secured in a rear seat in the appropriate child restraint. If, on the other hand, the dealer says your sensing and diagnostic module is the only component that needs to be replaced, you might want to consider doing this plug and play replacement at home. The first components to react in a crash are the crash sensors. They’re located on the RCM harness connectors and on any connector inline to a deployable component. How to Disarm Anti-Theft Lock We don't sell/share your email.

If the air bag sensors are damaged, they'll need to be replaced. This next case wasn’t so easy. Example: "Bad Brakes", "Toyota Recall", etc. They are roughly ordered by importance, which tends to be by color (red, amber, …

By shorting the two wires that connect to an air bag or pretensioner, the shorting bar renders them “safe.” This prevents static electricity or mishandling of the connecter from setting off the air bag. Early models that did not utilize passenger occupation sensors were sometimes equipped with an ignition key-activated switch that enabled the driver to manually deactivate the passenger air bag. Seat belt utilization is determined by a sensor in the buckle or the retractor.
