Test Description

WARNING: This page is about a different car, the 2005 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

The number below refers to the step number on the diagnostic table.

5: This step tests the ignition 1 voltage circuit for an open, a short to ground, or a high resistance.

Cruise Control Inoperative/Malfunctioning (2.2L)

Step	Action	Yes	No
Schematic Reference: Cruise Control Schematics Connector End View Reference: Powertrain Control Module (PCM) Connector End Views in Engine Controls - 2.2L (L61) or Computer/Integrating Systems Connector End Views in Computer/Integrating Systems
1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Install a scan tool. Turn ON the ignition, with the engine OFF. Turn the cruise control On/Off switch ON. With the scan tool, observe the Cruise Control Switch parameter in the body control module (BCM) Data list. Does the Cruise Control Switch parameter display On?	Go to Step 3	Go to Step 5
3	With the scan tool, observe the Cruise Control Switch parameter. Turn the cruise control On/Off switch ON. Press and hold the cruise control Set/Coast button. Does the Cruise Control Switch parameter display Set?	Go to Step 4	Go to Step 8
4	With the scan tool, observe the Cruise Control Switch parameter. Press and hold the Resume/Accel switch. Does the Cruise Control Switch parameter Display Resume?	Go to Diagnostic Aids	Go to Step 8
5	Turn OFF the ignition. Remove the inflatable steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement in SIR. Disconnect the cruise control switch. Turn ON the ignition, with the engine OFF. Connect a test lamp between the ignition 1 voltage circuit and a good ground. Does the test lamp illuminate?	Go to Step 6	Go to Step 10
6	Turn OFF the ignition. Connect a 3-ampere fused jumper between the ignition 1 voltage circuit, the cruise control set/coast and resume/accel switch signal circuit. Turn ON the ignition, with the engine OFF. With a scan tool, observe the Cruise Control Switch parameter. Does the Cruise Control Switch parameter display 5 volts?	Go to Step 8	Go to Step 7
7	Test the cruise control switch signal circuit for the following: A high resistance An open A short to ground Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 13	Go to Step 9
8	Inspect for poor connections at the harness connector of the cruise control switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 13	Go to Step 11
9	Inspect for poor connections at the harness connector of the BCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 13	Go to Step 12
10	Repair the following in the ignition 1 voltage circuit. An open A high resistance A short to ground Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you complete the repair?	Go to Step 13	-
11	Replace the cruise control switch. Refer to Steering Wheel Control Switch Assembly Replacement in Steering Wheel and Column. Did you complete the replacement?	Go to Step 13	-
12	Replace the BCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement?	Go to Step 13	-
13	Install the inflatable steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement in SIR. Enable the inflatable restraint steering wheel module. Refer to SIR Disabling and Enabling Zone 3 in SIR. Operate the vehicle within the conditions for cruise control operation. Does the Cruise Control System operate properly?	System OK	Go to Step 2
