Dodge Nitro. Manual — part 654

TURN SIGNAL CANCEL CAM

The turn signal cancel cam is concealed within the clockspring case on the steering column. The turn signal
cancel cam consists of integral eccentrics on the outer circumference of the molded plastic clockspring rotor.
The clockspring mechanism provides turn signal cancellation as well as a constant electrical connection
between the horn switch, driver airbag, speed control switches, Electronic Vehicle Information Center (EVIC)
switches and remote radio switches on the steering wheel and the instrument panel wire harness on the steering
column. The housing of the clockspring is secured to the steering column and remains stationary. The rotor of
the clockspring, including the turn signal cancel cam lobes rotate with the steering wheel.

The turn signal cancel cam is serviced as a unit with the clockspring and cannot be repaired. If ineffective or
damaged, the entire clockspring unit must be replaced. Refer to REMOVAL .

OPERATION

TURN SIGNAL CANCEL CAM

When the left multi-function switch control stalk is moved to a latched turn signal ON position, a turn signal
cancel actuator is extended from the inside surface of the switch housing through a small rectangular opening
on the left side of the clockspring case toward the turn signal cancel cam. As the steering wheel is rotated to
complete the turn, one of the cam eccentrics will contact the actuator, automatically cancelling the turn signal
event and releasing the latched left multi-function switch control stalk to the neutral or OFF position.

2007 ENGINE Fuel System - Nitro

A fuel return system is provided within the fuel pump module using check valves. A separate fuel return line
from the engine to the tank is not used.

The fuel pressure regulator and the main fuel filter are combined within the fuel pump module.

The fuel tank assembly consists of: the fuel tank, fuel pump module assembly, fuel pump module lock
ring/gasket, ORVR components. Refer to DESCRIPTION .

A fuel filler/vent tube assembly using a pressure/vacuum, 1/4 turn fuel filler cap is used. A one-way check valve
is installed into the tanks fuel fill fitting.

Also to be considered part of the fuel system is the evaporation control system and ORVR system. This is
designed to reduce the emission of fuel vapors into the atmosphere.

Both fuel filters are designed for extended service. They do not require normal scheduled maintenance.
