The Diagnostic Indicator Pattern 1 is a confirmation that the object alarm system has successfully entered the diagnostic mode. If the Diagnostic Indicator Pattern 1 does not display after an attempt to enter the diagnostic mode, it may be as a result of not entering the system diagnostic mode successfully or an RPA diagnostic input circuit fault is present. After the Diagnostic Indicator Pattern 1 is displayed, observe the RPA display for the next Diagnostic Indicator Pattern displayed. The indicator pattern displayed after the Diagnostic Indicator Pattern 1 is the diagnostic indicator pattern that actually needs be diagnosed. Proceed to the appropriate Diagnostic Pattern in this table. Refer to Diagnostic Trouble Code (DTC) Displaying .

1. Ignition ON, verify the scan tool can communicate with right side object sensor. If the scan tool can not communicate with the right side object sensor, refer to «Circuit/System Testing»(ref-338154-S25380151172009081700000) , under Right Side Object Sensor Malfunction
2. Verify the scan tool can communicate with left side object sensor. If the scan tool can not communicate with the left side object sensor, refer to «Circuit/System Testing»(ref-338154-S25380151172009081700000) , under Left Side Object Sensor Malfunction
3. Ignition ON, verify that the side blind zone alert system indicators located in the outside rearview mirrors briefly turn ON and then turn OFF during the system self test. If both indicators do not briefly illuminate during the system self test, the side blind zone alert system has been disabled. Refer to Diagnostic Aids. If only one indicator does not briefly illuminate during the self test, refer to «Circuit/System Testing»(ref-338154-S25380151172009081700000) , under Side Object Indicator Malfunction.

Lane Crossing Alerts

A lane crossing alert consists of the following

1. Chimes are activated through the vehicle audio system.
2. The VDAAW indicator that is normally green will turn to flashing amber.

The VDAAW system will not give any lane crossing alerts under the following conditions

1. Vehicle speed is less than 35 mph.
2. The system cannot detect lane markings.
3. The correct turn signal is activated. An activated turn signal is interpreted as an intentional lane crossing.

VDAAW DIC Messages

The VDAAW system commands the DIC to display the following messages to alert the driver of a system concern or status information

1. SERVICE LANE DEPARTURE SYSTEM
2. LANE DEPARTURE SYSTEM UNAVAILABLE

Side Object Sensors

The side object sensors are each located behind the rear fascia, positioned so that the sensor is pointing out toward the opposite lane. Each sensor is supplied B+ and ground. The right sensor receives an additional ground. Both sensors communicate independently on the serial data line. The serial data enters the right sensor in a pass-thru configuration, the connects to the left sensor. The scan tool is able to individually communicate with each sensor.

When a vehicle or object is detected by a side object sensor, a serial data message is sent to the appropriate door module to illuminate the indicator located in the outside rearview mirror.

Door Modules

The driver and passenger receive serial data messages from the side object sensors. When a message is received indicating that a vehicle or object is in the blind spot, the appropriate door module will apply voltage to the indicator located in the outside rearview mirror, illuminating the indicator. The door module provides a continuous low reference circuit for the indicator.

Outside Rearview Mirror

The outside rearview mirrors each contain an indicator that is controlled by the appropriate door module. This indicator is illuminated when a vehicle or object is position in the vehicle's blind spot.

SIDE BLIND ZONE ALERT SYSTEM OFF

This message indicates that the system has been disabled through the DIC. Refer to the vehicle owners manual for instructions on how to set personalization options on the DIC.

SIDE BLIND ZONE SYSTEM UNAVAILABLE

This message indicates that the system has been disabled because the sensor is blocked or can otherwise not accurately detect vehicles or objects. Such instances may be mud, dirt, snow, ice, or slush build-up on the rear fascia, heavy rainfall, or excessive road spray.

SERVICE SIDE BLIND ZONE ALERT SYSTEM

This message indicates that the system requires service. When the message is displayed, the indicators will remain illuminated at all times, notifying the driver that the SBZA system should not be relied upon when changing lanes.
