If the ABS warning indicator status message is missing for less than 5 seconds, the IPC defaults the ABS warning indicator to its last state (on or off) based upon the last message received.
If the ABS warning indicator request message is missing for longer than 5 seconds, the IPC sets DTC U0121:00 and defaults the ABS warning indicator on.
