Normal Operation

WARNING: This page is about a different car, the 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The wait to start signal is transmitted to the instrument cluster over the communication network from the powertrain control module (PCM). The wait to start indicator illuminates when the key is in the ON position with the engine OFF (KOEO) indicating that the glow plugs are heating.
