Ignition Sequence
When the ignition is turned on, the ICU runs a self-check. Observing the ignition sequence is a good way to ensure the ICU is functioning properly.
Important: Do not crank the engine until the ICU self-check is complete.
ICC5
Note: There is no Lane Departure Warning audible self-test.
When the ignition is turned on, the following actions should occur in the ICC5:
-
The logos for the engine and transmission display on the infotainment screen.
-
If installed, an Active Brake Assist (ABA) popup disclaimer appears on the driver display screen.
-
If ignition status is set to Adaptive Cruise Control (ACC), the tripmeter and odometer values are shown on the driver display screen.
-
If the ignition is set to ON, all ICC5 screens and options are available.
Important: If any red or amber warnings do not go out after the self-check completes, take the action outlined in the Warnings, Indicators, and Messages section in this chapter, then take the vehicle to an authorized Freightliner service facility as soon as possible.
