DTC P0564 for Holden Barina 2007

Circuit Description

The cruise control switch is an input to the engine control module (ECM). The ECM monitors the cruise control set/coast and resume/accelerate switch signal circuit in order to detect when a cruise control function has been requested. The ECM detects a specific voltage signal on the cruise control set/coast and resume/accelerate switch signal circuit when a cruise control function switch is activated, with each switch having a different predetermined voltage value.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0564 Cruise Control Multi-function Switch Circuit

Conditions for Setting the DTC

•	The engine is running.

•	Ignition voltage is greater than 7.9956 volts.

Action Taken When the DTC Sets

•	The malfunction indicator lamp (MIL) will not illuminate.

•	The ECM will record operating conditions at the time the diagnostic fail. This information will be stored in the Freeze Frame and Failure Records buffers.

•	A history DTC is stored.

Conditions for Clearing the MIL/DTC

•	A history DTC will clear after 40 warm-up cycles without a fault.

•	DTCs can be cleared by using the scan tool.

Diagnostic Aids

For an intermittent condition, refer to Testing for Intermittent Conditions and Poor Connections .

Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle

Turn the ignition OFF.
Disconnect the cruise control switch connector.
Turn ON the ignition, with the engine OFF.
With a DMM, measure the voltage of the ignition 1 voltage circuit.

Does the voltage measure at the specified value?

B+

Go to Step 3

Go to Step 7

Turn OFF the ignition.
With a DMM, measure the resistance of the cruise control switch between the connector terminal 1 and the terminal 4 respectively, while pressing the cruise control switch ON and OFF.

Does the cruise control function switch resistance values measure between the specified values?

Switch On = ∞ ohms

Switch Off = 0 ohms

Go to Step 4

Go to Step 5

Test the cruise control set/coast and resume/accelerate switch signal circuit for a high resistance, a short to voltage, or a short to ground between the cruise control switch and the engine control module (ECM).

Did you find and correct the condition?

Go to Step 10

Go to Step 6

Inspect for poor connections at the connector of the multifunction switch. Refer to Testing for Intermittent Conditions and Poor Connections .

Did you find and correct the condition?

Go to Step 10

Go to Step 8

Inspect for poor connections at the harness connector of the ECM. Refer to Testing for Intermittent Conditions and Poor Connections .

Did you find and correct the condition?

Go to Step 10

Go to Step 9

Repair the high resistance in the ignition 1 voltage circuit.

Did you complete the repair?

Go to Step 10

Once the replacement is complete verify the repair.

Did you complete the repair?

Go to Step 10

Replace the ECM. Refer to:

•	Engine Control Module Replacement for the 1.2L engine

•	Engine Control Module Replacement for the 1.4L DOHC engine

•	Engine Control Module Replacement for the 1.4L SOHC engine

•	Engine Control Module Replacement for the 1.5L engine

•	Engine Control Module Replacement for the 1.6L (L91) engine

Did you complete the replacement?

Go to Step 2

Use the scan tool in order to clear the DTCs.
Operate the vehicle within the Conditions for Setting the DTC.

Does the DTC reset?
