2. Observe the scan tool transmission data ignition voltage parameter. The reading should be between 12.6-15.0 V.
Circuit/System Testing
1. Ignition OFF, disconnect the X1 Q8 control solenoid assembly harness connector at the transmission.
2. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuits listed below and ground.
* Terminal 4
* Terminal 12
瀚慖f the test lamp does not illuminate, test the ignition circuit for a Short to Ground or an Open/High Resistance.
3. If all circuits test normal, replace the Q8 control solenoid valve assembly.

Diagnostic Fault Information
Circuit/System Description
The cruise control switch is an input to the body control module (BCM). The BCM monitors the cruise control on/off, set/coast, resume/accelerate
and cancel switches via the cruise control switch signal circuit in order to detect when the driver has requested to perform a cruise control function.
The BCM detects a specific voltage signal on the cruise control switch signal circuit when a switch is applied. The BCM sends a serial data
message to the ECM indicating the status of the cruise control switches.
Conditions for Running the DTC
* The ignition is ON.
* The cruise switch is ON.
