Lost Communication with Side Restraints Control Module Left
The Side Restraints Control Module Left has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Left-side airbags may not deploy in a crash. Safety-critical. Typical causes are loss of power or ground at the module, an open or shorted CAN/LIN bus wire, a connector fault, or an internal module failure.
