The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment of an Auto Volume Error message displayed on the radio when the Auto Volume button is pressed. Concern may be intermittent and will occur when the button is pressed with the ignition in RAP or ACC mode. This is due to the Vehicle Speed Sensor (VSS) message not being sent to the Radio in these specific ignition modes.
Recommendation/Instructions:
Normal operation. The vehicle must have the engine running or be in "Ignition On Engine Off" mode for at least 2 to 5 seconds before the Auto Volume selections will appear. Replacing the Radio or any other component will not correct this concern. It is a normal operating characteristic.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
