Fail-Safe Functions
WARNING: This page is about a different car, the 1997 Acura 3.5RL. However, it is still accessible from the selected car via links, so may be relevant.
During a multiplex control unit or communication line failure, output signals will use default values until fault is corrected. Each multiplex control unit has hardware fail-safe output signal defaults when there is a CPU failure. There are also software fail-safe defaults that ignore faulty multiplex control unit signals and allow system to continue to function.
