Principles of Operation: Notes

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

When installing a new instrument cluster, it is necessary to upload the module configuration to the diagnostic tool. Following installation of the new instrument cluster, download the module configuration from the diagnostic tool into the new instrument cluster. For additional information, refer to MODULE CONFIGURATION . The following items are configurable:

seatbelt telltale
seatbelt telltale timeout
seatbelt chime
belt minder
base door ajar tone (Escape, Mariner)
anti-theft telltale (Escape Hybrid)
check cap
speedometer bias
transmission type (Escape, Mariner)
key reminder chime
default language
ABS/TCS/IVD
4x4 (Escape Hybrid)
4WD (Escape, Mariner)
oil change reminder
not in park chime
turn signal on reminders
park brake on
button press chime
key off dimming timer
IFE/AFE/TFE navigation config (Escape Hybrid)
tire pressure monitoring system (TPMS)

The instrument cluster contains a microprocessor, gauges, indicator lamps, and internal circuitry. The instrument cluster and the smart junction box (SJB) use a combination of hardwired circuitry and the controller area network (CAN) to transmit and receive information. For additional information regarding the communication network, refer to MODULE COMMUNICATIONS NETWORK . It is very important to understand:

where the input (command) originates from.
all the information (messages) necessary in order for a feature to operate.
which module(s) receive(s) the input or command message.
if the module which received the input controls the output of the feature, or if it sends a message over the CAN to another module.
which module controls the output of the feature.

Each time the ignition switch is turned from OFF to ON, the charging system indicator, the low oil pressure indicator, and the malfunction indicator lamp (MIL) prove out and remain on until the engine is started and running normally. The safety belt indicator proves out for 60 seconds or until the safety belt is fastened. The air bag indicator proves out for approximately 6-8 seconds while the following instrument cluster indicators and warning indicators prove out for approximately 3 seconds:

ABS warning indicator
THEFT warning indicator
brake warning indicator
check fuel cap warning indicator (Escape, Mariner)
4x4 indicator (Escape, Mariner)
low fuel level warning indicator (Escape, Mariner)
hazard warning indicator (Escape Hybrid)
service soon warning indicator (Escape Hybrid)
overtemp warning indicator
TPMS warning indicator
