Cruise Control ON Signal: General Electrical Failure
Cruise Control Multifunction Input A Circuit Stuck
The
PCM
compares the
CAN
signal from the different inputs of the cruise control switches and determines that one or more of the switches are stuck.
DIAGNOSE all other
IPC
and
PCM
Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, CLEAR the
DTC
. Make sure no cruise control switches are pressed and REPEAT the self-test. If
DTC
P0578 sets again, INSTALL a new
PCM
. Refer to the appropriate section in Group 303 for the procedure. TEST the system for normal operation.
P0579
Cruise Control Multifunction Input A Circuit Range/Performance
The
PCM
internally monitors and compares the
CAN
signal message from the
IPC
of the cruise control switch inputs with the
PCM
cruise control internal state. If the
PCM
detects a discrepancy between the input message and the
PCM
then
DTC
P0597 sets in the
PCM
. DIAGNOSE all other
IPC
and
PCM
Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, CLEAR the
DTC
. REPEAT the self-test. If
DTC
P0597 sets again, INSTALL a new
PCM
. Refer to the appropriate section in Group 303 for the procedure. TEST the system for normal operation.
Internal Control Module Cruise Control Performance
The
PCM
internally monitors the disable inputs for cruise control. If a cruise control disable is requested and the cruise control
output from the
PCM
is still being controlled then
DTC
P162D sets in the
PCM
. DIAGNOSE all other Diagnostic Trouble Codes (DTCs) and symptoms first. If no other Diagnostic Trouble Codes (DTCs) or symptoms
are present, INSTALL a new
PCM
. Refer to the appropriate section in Group 303 for the procedure. TEST the system for normal operation.

A MyKey® restricted key is in use and MyKey® max speed limiter is turned on
VERIFY whether a MyKey® restricted key is in use. With an admin key, VERIFY if MyKey® speed limiter is turned on. REFER to

Pinpoint Tests
The Cruise Control Is Inoperative
Refer to Wiring Diagrams Cell 31 for schematic and connector information.
Normal Operation and Fault Conditions
The cruise control functionality is controlled through the brake pedal switch that is hard-wired to the
PCM
through a signal and return circuit, and a cruise control deactivator switch that is hard-wired to the
IPC
. There are 5 cruise control switches with each switch operating a specific function that uses different resistance values.
The
IPC
sends out a reference voltage to the cruise control switches and monitors the voltage drop when a cruise control switch is
pressed. The voltage drop varies depending upon the resistance of each switch, providing a specific indication to the
IPC
which switch is pressed.
The
IPC
sends a network message over the High Speed Controller Area Network (HS-CAN) to the
PCM
relaying the switch status and requesting cruise control operation. The stoplamp switch is an input to the
PCM
for the cruise control operation. When the brake pedal is applied, the normally open stoplamp switch closes and applies
a voltage signal to the
PCM
deactivating the cruise control, if engaged. The cruise control deactivator switch is a normally closed switch that provides
a ground signal to the
IPC
. When the brake pedal is applied, the switch opens and removes the ground signal to the
IPC
.
The
IPC
sends a network message over the
HS-CAN
to the
PCM
. This is a redundant signal to the
PCM
. The
PCM
receives both signals and compares the inputs to confirm the correct brake input sequence is received.

Normal operation and Fault Conditions
The stoplamp switch and cruise control deactivator switch signals are inputs to the
PCM
and the
IPC
respectively for the cruise control operation. When the brake pedal is applied, the normally open stoplamp switch closes
and applies a voltage signal to the
PCM
deactivating the cruise control, if engaged. The cruise control deactivator switch is a normally closed switch that provides
a ground signal to the
IPC
. When the brake pedal is applied, the switch opens and removes the ground signal to the
IPC
. The
IPC
sends a network message over the High Speed Controller Area Network (HS-CAN) to the
PCM
. This is a redundant signal to the
PCM
. The

P0833
Normal Operation and Fault Conditions
Vehicles equipped with a manual transaxle have an additional clutch pedal cruise control deactivator switch. The clutch pedal
cruise control deactivator switch is a normally open switch with the clutch pedal released. When the clutch pedal is pressed,
the clutch pedal cruise control deactivator switch moves to the closed position, which routes the ground signal to the
IPC
. The
IPC
sends a network message over the High Speed Controller Area Network (HS-CAN) to the
PCM
, deactivating the cruise control system.
This is a logic based
DTC
that sets when the
PCM
receives the vehicle speed input, indicating vehicle movement and does not detect the switching input from the
CPP
switch or clutch pedal cruise control deactivator switch. This condition disables cruise control.
