P0565

Diagnostic Chart:

Wiring Diagram:

Command state voltage levels are divided through a resistor network from ignition voltage provided through the 5A cruise fuse. The network consists of resistors both in the cruise control switch and internal PCM. If the voltage level is within an acceptable window for all three switches, the PCM decodes the command. If voltages are outside the windows, DTC P0565 will set.

DTC PARAMETERS
DTC will set if:
^ Cruise switch On less than 0.5 volts or greater than 1.0 volts at circuit 1884.
^ RESUME/ACCEL switch depressed, less than 1.2 volts or greater than 1.7 volts at circuit 1884.
^ SET/COAST switch depressed, less than 3.0 volts or greater than 3.5 volts at circuit 1884.

IMPORTANT: Voltage windows vary depend ant to B+ calculations.

DIAGNOSTIC AIDS
^ Inspect malfunction history data. Attempt to distinguish which portion of switch input was lost. Attempt to reproduce.
^ Shorts high or low in circuit 1884 will result in an inoperative system.
^ Intermittents: Inspect harnesses, observe parameters on Scan tool while moving harnesses and connectors.
