circuit.
More Than Full Stop Message - Each time the cluster receives a fuel level message indicating the fuel
level in the fuel tank is more than the F (or Full) gauge needle stop position for five consecutive seconds,
the gauge needle is moved to the low end of the gauge scale and the low fuel indicator is illuminated
immediately. This input would indicate that the fuel level sense input to the TIPM is an open circuit.
The TIPM continually monitors the fuel tank sending unit to determine the level of fuel in the fuel tank. The
TIPM then sends the proper electronic fuel level message to the Electro Mechanical Instrument Cluster (EMIC)
(also known as the Cab Compartment Node/CCN) and other electronic modules in the vehicle over the
Controller Area Network (CAN) data bus. The TIPM will store a Diagnostic Trouble Code (DTC) for any fault
detected in the fuel level sense circuit.
For proper diagnosis of the fuel tank sending unit, the TIPM, the EMIC, the CAN data bus or the electronic
communication related to low fuel indicator operation or fuel level data processing a diagnostic scan tool is
required. Refer to the appropriate diagnostic information.
LOW OIL PRESSURE INDICATOR
DESCRIPTION
LOW OIL PRESSURE INDICATOR
Fig. 27: Low Oil Pressure Indicator
Courtesy of CHRYSLER LLC
A low oil pressure indicator is standard equipment on all instrument clusters. This indicator is located near the
bottom of the speedometer dial face of the cluster overlay, just left of center.
The low oil pressure indicator consists of a stencil-like cutout of the International Control and Display Symbol
icon for Engine Oil in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting Diode (LED)
behind the cutout in the opaque layer of the overlay causes the indicator to appear in red through the translucent
outer layer of the overlay when it is illuminated from behind by the LED, which is soldered onto the instrument
cluster electronic circuit board.
The low oil pressure indicator is serviced as a unit with the instrument cluster.
