Mazda CX-5 Service & Repair Manual: Low Fuel Warning Light
Purpose
-
The low fuel warning light warns the driver that the remaining fuel level is low.
Function
-
The instrument cluster calculates the fuel quantity based on the following CAN signals, and if a remaining fuel amount of approx. 10 L {2.6 US gal, 2.2 Imp gal} (fuel gauge displays remaining two segments) is detected, the low fuel warning light illuminates.
-
Fuel gauge sender unit voltage signal sent from rear body control module (RBCM)
-
Fuel injection amount signal, vehicle speed signal sent from PCM
Construction
-
The instrument cluster microcomputer controls the low fuel warning light illumination on/off based on the remaining fuel amount calculation that is calculated by the instrument cluster.
-
The low fuel warning light is set in the instrument cluster.
Operation
-
When the ignition is switched ON (engine off or on) the instrument cluster receives (1) the fuel gauge sender unit voltage signal from the rear body control module (RBCM), and the fuel injection amount signal from the PCM.
-
The instrument cluster turns the transistor on (2) if the calculated remaining fuel amount based on each signal is approx. 10 L {2.6 US gal, 2.2 Imp gal}.
-
When the transistor turns on, a ground circuit with the low fuel warning light is established and the low fuel warning light illuminates (3).
Fail-safe
-
Function not equipped.

Purpose, Function
Timing chain
The timing chain transmits the rotation force of the crankshaft to the camshaft
to perform the rotation timing of the crankshaft and camshaft.

The chain tensioner constantly maintains the timing chain tension and the
timing ch ...
ABS Control
Outline
ABS control occurs when wheel slip is determined by the DSC CM (based on
the four ABS wheel-speed sensors). Then, the DSC HU inlet and outlet solenoid
valves are operated and brake fluid pressure is controlled accordingly to prevent
wheel lock-up.
