Blind Spot Information System (BLIS®)

BLIS® becomes active the first time the transmission is placed in DRIVE (D) after starting the engine and driving forward at a vehicle speed greater than 4.8 kmh (3 mph). Upon that initial sequence, BLIS® remains active for all speeds including 0 kmh (0 mph). BLIS® is also active if the transmission is placed in NEUTRAL (N). If the transmission is shifted out of DRIVE (D) or NEUTRAL (N), the system has entered the CTA mode. When the transmission is shifted back into DRIVE (D), BLIS® is activated once the vehicle is driven above 4.8 kmh (3 mph).

BLIS® can trigger an alert for vehicles that enter the blind zone from the rear or merge into the blind zone from the side. The exterior mirror BLIS®/CTA amber LED illuminates in the right and/or left exterior mirror. For vehicles that pass through the blind zone quickly, typically less than 2 seconds, BLIS® cannot trigger an alert.

For correct operation of BLIS®, the rear side bumper cover should be free of obstructions such as a large build-up of mud, snow or ice. Small build-up of debris and materials does not hinder the operation of the system. There should be no bumper stickers of any type placed in this area of the bumper cover.

Note. No filler material should be used for repairing the bumper in the area in front of the SOD-L or SOD-R field of view.

Note. BLIS® does not normally detect parked vehicles, pedestrians or objects such as fences, guard rails, trees, etc. BLIS® does not provide any additional warning when the turn signal is activated.

Due to the nature of radar technology, false alerts and missed vehicles or objects (referred to as targets) may occur under certain circumstances. False alerts occur when the LED illuminates with no target present. False alerts up to 3% (3 out of 100 targets) is normal operation. Circumstances that cause false alerts are

1. Freeway dividers
2. Concrete walls
3. Fencing or vegetation
4. Sharp turns around a pole or building
5. Coming to a stop with a vehicle directly behind and very close

False alerts are temporary and self-correcting.

Missed targets occur when a target is present and the LED does not illuminate. Missed targets up to 1% (1 out of 100 targets) is normal operation. Circumstances that cause missed targets are

1. Debris build up on the rear bumper sides
2. Certain maneuvering of vehicles entering and exiting the blind zone
3. Vehicles passing through the blind zone at high rates of speed
4. Severe weather conditions
5. When several vehicles forming a convoy pass through the blind zone

Cross Traffic Alert (CTA) System

The CTA system is an alert feature that assists the driver in backing out of a front-in parking space. The CTA system uses the SOD-L, SOD-R, exterior mirror BLIS®/CTA LEDs, a warning chime from the audio speakers and a message in the IPC message center to notify the driver of impending traffic.

When the vehicle is in REVERSE (R), the CTA system can detect a vehicle that is approaching at a speed up to 24.1 kmh (15 mph) and is approximately 13.72 m (45 ft) from the side of the vehicle on the left or right side. The CTA system response time and performance can degrade if vehicles are approaching at speeds greater than 24.1 kmh (15 mph).

The CTA system detects a vehicle approaching up to 13.72 m (45 ft) away (approximately the width of 5 parking spaces). Backing out of parking spaces slowly increases the radar sensor coverage in close proximity situations. The CTA system coverage also decreases when parking at shallow angles, as described in the Owner's Literature.

The CTA system utilizes the same SOD-L and SOD-R as the BLIS®.

When the transmission is in REVERSE (R), the CTA system is active. The driver is warned of an approaching vehicle when an audio alert chime from the audio system speaker sounds, the right or left exterior mirror BLIS®/CTA amber LED flashes, and the message center displays CROSS TRAFFIC VEHICLE COMING FROM RIGHT or CROSS TRAFFIC VEHICLE COMING FROM LEFT to warn the driver from which direction the vehicle is approaching.

The CTA system cannot normally detect stationary vehicles, humans, animals or objects such as fences, guard rails or trees. The system does not function when the transmission is not in REVERSE (R).

The CTA system has some detection limitations due to the nature of the radar technology for the SOD-L and SOD-R. There can be certain instances where vehicles entering and exiting the blind spot zone may not be detected. The circumstances that may cause non-detection are

1. Debris build-up on the rear bumper sides
2. The rear quarter panel of the vehicle is obstructed or partially obstructed by an adjacently parked vehicle or object
3. Approaching vehicle passing at speeds greater than 24.1 kmh (15 mph)
4. Severe weather conditions
5. Driving in REVERSE (R) faster than 4.8 kmh (3 mph)
6. Backing out of an angled parking spot

Due to the nature of radar technology, there may be certain instances when the CTA system alerts the operator, however no object or vehicle (referred to as targets) is present when backing up. This is known as a false alert. False alerts up to 5% (5 times out of 100 reversals) are normal. A false alert may occur when backing out of a garage or backing into a parking space and objects or vehicles are very close to the radar sensors. False alerts are temporary and self-correcting.

Exterior Mirror Indication

The SOD-L and SOD-R run a self-diagnostic check on each vehicle start cycle and command the DDM and PDM to illuminate the exterior mirror BLIS®/CTA amber LEDs for approximately 3 seconds indicating the BLIS® and CTA is operational.

If a BLIS® fault is present, the LEDs remain illuminated and a message in the message center displays BLIND SPOT SYSTEM FAULT. System faults can occur that cause the associated left or right exterior mirror BLIS®/CTA amber LED not to illuminate; only the message center message fault is displayed.

BLIS® and CTA Message Display

Note. The CTA system faults may not occur until the transmission is placed in REVERSE (R).

BLIS® can be turned off by selecting the blind spot on/off function in the message center. The amber BLIS® indicator is illuminated in the message center. When turning BLIS® from off to on, the exterior mirror BLIS®/CTA amber LEDs illuminate for about 3 seconds. When BLIS® is off, the driver cannot receive any alerts. The system is reactivated on the next ignition cycle.

The CTA system can be turned off by selecting the CTA system on/off function in the message center. The CTA system can only be deactivated in the message center when the transmission is in REVERSE (R). The system is reactivated on the next ignition cycle.

There are some system faults that set DTCs which are logged in the SOD-L or SOD-R. These DTCs can set a message in the IPC message center that displays CROSS TRAFFIC SYSTEM FAULT or BLIND SPOT SYSTEM FAULT. There are also some symptom based faults that do not set a DTC.

Blocked Sensor

Note. A blockage will only be checked for if the wipers are on for more than 30 seconds.

An excessive build-up of materials on the left and/or right rear bumper sides, such as mud or snow, can cause the BLIS® or CTA system functionality to degrade. Heavy rain can have the same effect. If the system is in a blocked state, the radar misses targets, but still counts them. After approximately 4 counted/missed targets, the SOD-L or SOD-R send a blocked sensor message over the extended MS-CAN to the BCM, then the BCM sends the message over the MS-CAN to the IPC. The message center displays BLIND SPOT NOT AVAILABLE SENSOR BLOCKED or CROSS TRAFFIC NOT AVAILABLE SENSOR BLOCKED message. If the blocked condition is determined by either system the message center displays BLIND SPOT NOT AVAILABLE or CROSS TRAFFIC NOT AVAILABLE and the left and right exterior mirror BLIS®/CTA LEDs illuminate.

The message center warning can be cleared by the driver, but the amber BLIS® indicator remains illuminated. Once the blockage is removed, the system requires some drive time and a system detection of at least 2 vehicle objects prior to realizing it is unblocked. The ignition can also be cycled OFF to clear the blocked state. However, if the blockage is still present after the ignition cycle and after some drive time, the system detects again that it is blocked. The blocked message is displayed again in the message center and the amber BLIS® indicator is illuminated again.

Due to the nature of radar technology, it is possible to get a blocked sensor warning without the radar sensor being blocked. This is rare and is known as a false blockage warning. A false blocked condition either self-clears or clears after an ignition cycle.

Side Obstacle Detection Control Module - Left (SOD-L)/Side Obstacle Detection Control Module - Right (SOD-R)

BLIS® and the CTA system utilizes 2 modules that have integral radar sensors located rearward of the rear wheel under the rear bumper cover. The 2 modules, SOD-L and SOD-R, use the extended MS-CAN to communicate with each other and the BCM.
