SRX RWD V8-4.6L VIN A (2006)
Fuel Gauge: Description and Operation
FUEL GAGE
The engine control module (ECM) sends fuel level percent to the instrument panel cluster (IPC) via class 2. The IPC displays the fuel level as
determined by the ECM. The IPC receives a class 2 message from the ECM indicating the fuel level percent. The fuel gage defaults to E (empty) if:
-
The ECM detects a malfunction in the fuel level sensor circuit.
-
The IPC detects a loss of class 2 communications with the ECM.
When the fuel level is less than 4 percent, the low fuel indicator illuminates. Refer to Evaporative Emission (EVAP) Control System Description in
Computers and Control Systems - 3.6L (LY7) or Engine Control Module (ECM) Replacement in Computers and Control Systems - 4.6L (LH2) for more
information.
