9.13.2 Front Dash Panel
The information under this heading deals mainly with the
description and function of each indicator in the front
dash panel. Appropriate service procedures for each
circuit, as applicable, appear elsewhere in this section of
the manual.
The front dash panel is of solid-state, printed circuit
design and contains one wiring plug and a display panel
that provides overall monitoring of vehicle functions and
status.
Prevent the panel from coming into contact with static or
other electrical sources. When washing the vehicle, keep
spray away from the front dash panel. Replace a
defective, malfunctioning or faulty panel with a new unit.
The front dash panel provides important information in a
“user friendly” design with easily-recognizable graphic
and alpha-numeric indicators. The panel provides
information the operator needs on vehicle and engine
functions.
When testing circuits connected to the dash, disconnect
the harness connector and test the harness side only.
CAUTION:
Before performing ANY
welding on vehicle, disconnect the negative (-)
battery cable at the negative (-) battery
terminal. Failure to remove the negative (-)
battery cable will result in damage to vehicle
electronic systems.
